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, arXiv, Google 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, arXiv or Google Scholar Citations 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.

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 and generated at arXiv 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.)

Contributions to conference proceedings

Titles in bold (8/21) refer to talks I gave. All other contributions (13/21) 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 (7/21 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, 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).

Only some of these items were posted to arXiv. If something wasn't posted, then probably for at least one of the following reasons:

Alternatively, if a proceedings contribution was posted to arXiv, it contains original research not available elsewhere, presents results available elsewhere in a more compact format, or presents results available elsewhere in a more detailed format.

    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.)

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. not talks given at the institute where I was working at the time nor at occasions such as network meetings, workshops etc.
