List of publications in one PDF file, sorted by type

Want to know why I've stopped submitting to arXiv?

An ideal present, for Christmas or any other occasion, for yourself or for anyone interested in astronomy, is a book which I have translated from German to English, namely The Cambridge Photographic Atlas of Galaxies (Cambridge as in Cambridge University Press). It is chock full of beautiful full-colour pictures of galaxies, with detailed descriptions of each object, often as a jumping-off point for discussion of more-general concepts, as well as several chapters of background material. The level is somewhere between a typical popular-astronomy book and a textbook. See the first link in this paragraph for links to reviews and the second for a preview and for ordering the book.

information about publication list

If you already know what you want, then you can go find it in either the
or in the With time, expect the to fill up, with both old and new stuff (some of the new stuff as PDF only).

Feel free to cite me! To make it easier, here's a BibTeX file which contains nothing but my publications! Entries preceded by ADS, Google, ORBi, or ARIBIB indicate in which, if any, databases the corresponding entry appears (see next paragraph). Note that the ARIBIB information is available only until the middle of the year 2000.

You can decrease the load on my server by getting stuff from ADS, Google Scholar Citations, or ORBi, but keep in mind that some of the information provided at these sites is automatic and perhaps not 100% reliable. At ORCID I have essentially the same stuff I have at Google Scholar Citations, which is not surprising since the entries at ORCID were created by importing BibTeX exported from Google Scholar and adding a bit more information.

The ADS query, should return 80 results. Note that it is not just a query on my name, since that returns (rightly or wrongly, I'm not sure) some papers which are not mine. I've also created a public ADS library which should contain the same publications as the query plus one due to a different surname and a book I translated but did not write (78), but check both to be sure since the library is maintained by hand. (Depending on what one is looking for, one or the other might be more useful.) There are also libraries for refereed publications in cosmology/astrophysics/astronomy (27) and other publications (51) (i.e. not normal refereed publications and/or not about cosmology/astrophysics/astronomy).

For more information about (including links to) my various publications, see the lists below. Here, page numbers in bold italics indicate that the main link to the official online version of the paper provides free access to the full paper. Otherwise, only part is available and/or some subscription is required. In such cases, if there is another link to the official online version which provides free access to the whole paper, this is listed separately before the DOI. (Usually, it is a link to the abstract where one can find links to PDF and, for all but the oldest papers, HTML versions.) (In order for this to work, you might occasionally have to delete some obviously named cookies from your computer and/or refresh your browser cache.) While DOIs themselves should always be valid, the actual site they resolve to can and does change. In some cases, DOIs now resolve to the same free, full version as that listed immediately before the DOI. Scanned articles at ADS are scans of the printed version, so this is another option to access the official content. The PostScript and PDF files on my site should correspond, except for minor matters of formatting, to the official versions, but keep in mind that these have been updated by hand when correcting the proofs. (In some cases, I don't have a self-generated PS or PDF file. Occasionally, this is the case for papers where I didn't actually physically write the paper and the original source has disappeared, so I have some scanned version from ADS. Most such cases are pieces for The Observatory which I did not write in LaTeX; here, I provide a PDF of the proof or, when it has become available, a scan from ADS. Note that the proofs might contain minor typos etc.)

A problem these days is having too many online publication lists, so here is a guide:

this page:
This page should be regarded as the master list.
ADS:
ADS is a tried and true traditional bibliographic database for astronomy. While some others contain a few more things, it is almost never wrong, and errors are corrected quickly by the friendly staff. I thus try to make sure that it is accurate. Only disadvantage is that the new site can be too slow for some folks.
Google Scholar:
Google has a bit more stuff than ADS, and usually finds stuff more quickly, but it is not always correct. Even though I have disabled automatic updates, sometimes after editing entries to correct them, my changes are reverted. Use it with a reasonably large grain of salt. I haven't found out how to contact a human in order to get obvious mistakes corrected. Despite the complexity, the page loads reasonably fast.
ORBi:
Since I was affiliated with the University of Liège, I was required to put publications (including full texts) on the university server there. It is thus reasonably complete and contains more information than the other databases. However, it is maintained by hand, so is not always up to date. Also, stuff goes there only when an official version is available. I plan to keep it updated as long as it exists and at least as long as I am affiliated with the University of Liège (enough so that they maintain the database of my stuff; apparently being an alumnus is enough). Interestingly, for a while the document most often downloaded from there (e.g. on 2022-09-24) was my Diplom thesis, which is in German. On 2023-11-19 it was my doctoral thesis (also at the University of Liège). I am no longer a student there and have no official affiliation, but can now access it as an alumnus and so plan to keep it up to date.
arXiv:
arXiv contains only stuff which I upload to arXiv, which is not everything. I have stopped submitting to arXiv until they change their policies and also commented out links to my papers at arXiv (hence such tags are no longer visible) until they clean up their act. (The fact that I didn't delete them, but just commented them out, shows that I still have hope that one day they will see the light.)
ORCID:
I signed up for ORCID since arXiv recommended it, and in the meantime several journals use it as well. The idea of having a unique author identifier is a good one. However, I don't see the point of maintaining a list of publications there. (It would be the obvious place, though, for someone whose field is not covered by ADS or Google Scholar, and for some might remove the need for a personal or institutional webserver for publications.) However, publications on ADS now show up there automatically, so I'll keep an eye on it.
ARIBib:
ARIBib is a bibliographic database which goes back a long way; it stops around the middle of 2000, due to more and more stuff becoming available online. Hence, the list of my things there is static. A good resource for older literature, though.
inSpire:
Some of my stuff can be found there, but I've never done much with it. My impression is that it is for particle physics what ADS is for astronomy, though obviously there is some overlap. When I have time, if it isn't too much trouble I might consider maintaining it like I do the ADS list (i.e. make sure that it is up to date and correct); in that case I would add links to inSpire for my stuff on this page. UPDATE: I've found and claimed some more stuff, and requested that more stuff be added to the database (which I can then claim). It now has almost all of my refereed-journal papers (missing those in The Observatory and a recent onewhich I have requested to be added). Like at Google Scholar, it is not clear to me why some non-refereed stuff shows up while other stuff, even though published in the same place, does not. It appears that some cosmology/astrophysics/astronomy is considered appropriate and some is not. Thus, my profile there will probably always be incomplete. NEWER UPDATE: It now has all refereed-journal publications except those from The Observatory, which it considers not to be relevant to HEP. I agree, but neither are most or all of my other refereed-journal publications. I had requested that the latest papers be added; not sure if they would have been picked up automatically had I waited longer. Since it will presumably be incomplete regarding refereed-journal papers anyway, I see little point in trying to make it complete with regard to other works, especially since it is not clear what they would accept and what not and what criteria are used. I noticed this because a job ad wanted a link to an iNSPIRE profile.
Researchgate:
I signed up there only because someone asked me to comment on something (and I had to be signed up in order to do so). I've done little with it and don't plan on maintaining a list there. There is thus no link to my profile there, and I might delete it. UPDATE: I have now (2023-11-19) deleted my profile there because of their new affiliation with MDPI.
Academia.edu:
I don't recall ever doing anything with them, but I get regular emails asking about my publications.
other stuff:
Some sites might automatically set up some profile and spam me asking me to join or whatever. I don't pay attention to stuff like that, so if a site isn't mentioned in this list, it's probably one of those.
For information about what is included in which list and why, see the comments in the BibTeX file linked to above.

Contributions to conference proceedings

Titles in bold (9/22) refer to talks I gave. All other contributions (13/22) are posters, except #9, which was a talk given by Neal Jackson. #16 was an invited talk; the rest were contributed. At least those posters which I prepared myself (i.e. not prepared by a co-author), marked by an asterisk (7/22 total, 7/12 posters), are available both in the proceedings version and in the original poster version, the latter, in the case of those I prepared before 2010, as a single-page PostScript file available both in A0 and A4 sizes (except for the first one, which consists of multiple pages, because it was made before A0 printers became reasonably common and cheap; after 2010, I used scalable fonts, so could just print the A4 version at A0.).

    Note that there are several proceedings contributions which list one, two or a few authors plus "CLASS collaboration". Some of these gathered some or all of the co-authors listed in the conference programme into "CLASS collaboration" to save the space taken up by the names, affiliations etc of the authors in the limited space provided in proceedings contributions, especially in the case of posters since these are often allowed fewer pages. Thus, on the basis of a proceedings contribution which lists "CLASS collaboration" among the authors, it is not clear whether the original author list contained more names or not. Although officially part of the CLASS collaboration, I have not listed any of these proceedings contributions here, even though I was involved in some, except for the one above, since I was mentioned explicitly on the original poster. (The names of all authors (actually fewer than the entire CLASS collaboration), as listed above, appeared on the original poster. The published version lists S. T. Myers and the Class collaboration as authors. As a result, this is not listed at ADS under my name.)

Conference contributions not included in proceedings

Unlike some people, I have never failed to deliver a contribution to the proceedings if it was possible to have my contribution appear. So these are contributions which didn't appear in the published proceedings, for reasons beyong my control. Most are posters but also a regular talk and a pre-recorded flash talk. In general, proceedingsless contributions can occur either because the corresponding conference had no proceedings at all or because posters were not included. At the moment, only the former applies (but some of those conferences do have the slides of the talks online, which is becoming increasingly common). (Note that online-only proceedings, such as no. 21 above, are treated as other proceedings, which is appropriate since today many journals, and even some traditional journals, are online-only. In some cases, both a traditional book was published and the contributions it contains are available online—either individually or collectively—, as in nos. 20 and 22, respectively, above.)

Correspondence in The Observatory*

Although all of these contributions have been refereed, as is usual for such pieces in The Observatory, they are not really traditional refereed-journal papers, which is why I have not included them in the first section above; they are more like old-style letters to the editor.

Talks

The first item with links is for 2012. The reason is that before then my talks were given with transparencies displayed on old-fashioned overhead projectors and thus don't exist as a single file. The earlier ones were even hand-written and thus don't exist as a file at all (although some of the plots do). I will probably never put up the hand-written ones, since the only practical way would be to scan them, which is too much trouble. When I have some spare time, I might put up the ones which were done in LaTeX. (Unlike the ones of 2012 and later, not everything was in the PostScript file produced from LaTeX; in particular, some plots were "standalone" and not included into the LaTeX file.)

The subjects of most of the talks are covered in the refereed-journal articles and/or in the proceedings contributions. However, the talk versions include less text and more pictures, so at least in some cases it might be worth putting them up.

The list is incomplete before 2011. When I have time, I will add a list of the older talks, just for documentation purposes. However, these will be only "external" talks, i.e.;nbsp;not talks given at the institute where I was working at the time nor at occasions such as network meetings, workshops etc.
