\n\nPvdW would like to thank the organisers for a very enjoyable meeting. It was an honour to be able to discuss the cosmos in the same city where man first realized that nature lends itself to analysis by the human mind. Special thanks go to Padeli Papadopoulos and his family for excellent Greek hospitality.
", "abstract": "In this paper we review the present status and implications of Hα surveys at various redshifts. With the advent of sensitive wide-format near-infrared detectors on large telescopes, deep and extensive Hα surveys are now feasible to redshift z ∼ 2.5. The cosmic star formation history can therefore be traced out to this redshift using Hα alone, avoiding complications arising from the comparison of different tracers at different redshifts. The Hα surveys to date confirm the rapid increase in luminosity density from z = 0 out to z = 1, and show that this increase flattens off at higher redshifts, remaining approximately constant out to at least z ∼ 2.2. We also discuss the prospects for determining the masses of high redshift galaxies based on emission lines. A set of high-quality Hα rotation curves of samples of disk galaxies at a number of different redshifts would allow a study of the evolution of the Tully-Fisher relation and address fundamental issues in disk galaxy formation. Such a program remains challenging even with present-day large telescopes.

", "abstract": "Knowledge of the properties of the white-dwarf companions of radio pulsars can provide unique constraints on the characteristics and evolution of these binaries, as well as on those of its constituents. Many white-dwarf properties can be determined accurately from their spectra, but for the very faint pulsar companions spectroscopy has only become feasible with the advent of large telescopes like the Keck. Here, I introduce the two classes of pulsar, white-dwarf binaries, and describe for each what we have learned from a specific system, PSR J1012+5307 and PSR B0655+64, respectively, summarising what has been done (Van Kerkwijk & Kulkarni 1995; Van Kerkwijk, Bergeron, & Kulkarni 1996; hereafter Papers I & II), presenting new results, and discussing what the future may hold.", "date": "1997-05-31", "date_type": "published", "publication": "Astrophysics and Space Science Library", "publisher": "Springer Netherlands", "place_of_pub": "Dordrecht", "pagerange": "383-389", "isbn": "978-0-7923-4585-5", "issn": "0067-0057", "book_title": "White Dwarfs", "official_url": "https://authors.library.caltech.edu/records/7f20a-yn280", "local_group": { "items": [ { "id": "Palomar-Observatory" }, { "id": "Division-of-Physics-Mathematics-and-Astronomy" } ] }, "doi": "10.1007/978-94-011-5542-7_56", "pub_year": "1997", "author_list": "van Kerkwijk, M.
