Topics discussed include: his family and childhood; Bristol University; Nevill Mott; University College, London; Harrie Massey; David Robert Bates; theoretical physics seminars at Cambridge University; Richard Feymnan; Freeman Dyson; Dick Dalitz; Abdus Salam; Nicholas Kemmer; becoming interested in astronomy and astrophysics via Margaret Burbidge; Royal Astronomical Society; Clive Gregory; research into stellar parallax, stellar atmospheres; Herbert Dingle; Auger effect; Otto Struve; Harvard University; Bart Bok; Donald Me
In this interview Robert Cahn discusses his tenure and support of the Supernova Cosmology Project (SCP) as director (1991-1996) of the physics division at Lawrence Berkeley Laboratory (LBL). Reviews of the SCP. Saul Perlmutter as building a new field of research in distant supernovae. Astrophysics in Berkeley. Style of research in the physics division at LBL. On discoveries as gradual and the importance of statistics and systematics. Pentaquark discovery as an example of error.
Deals with the events leading up to and the discovery of the Crab Nebula Pulsar. Comments on his education at Cornell University and switch to astrophysics. Teams up with Michael Disney at Steward Observatory for their first observation on a 36-inch telescope. Discovery of the Vela Supernova remnant pulsar convinces them to concentrate on the Crab Nebula rather than white dwarfs. Discussion of preparations, of observations, and of the discovery. Reaction to the discovery, effect on future work. Also mentioned are: Robert McAllister, Don Taylor, and Dr. Weyman.
Galaxy cluster cataloging, and toward finding supernovae started in 1984 while professor in Durham, England. Collaboration with Danish astronomers, using telescope at European Southern Observatory in Chile on this search. Thus, with ground-based telescopes obtained the spectra of the supernovae and measured their redshifts. Result: Nature paper of 1989. Collaboration with The Supernova Cosmology Project (SCP) beginning in 1993. Carl Pennypacker first PI of SCP. Camera at Anglo-Australian Telescope (1000 by 2000 pixels, as opposed to 600 by 500 pixels of Danish camera).
Gerson Goldhaber describes the milestones and turning point in the Supernova Cosmology Project's history; the discovery of the first supernova after three years, then discovering batches of supernovae at a time, the use of a 10 meter Keck telescope to get spectra taken. Goldhaber describes his tables of supernovae. He explains how two images are taken each time when searching for supernovae, to avoid hot pixels, cosmic rays, and asteroids in the data. Goldhaber's discovery of a peak in the data, shown in Santa Barbara on December 14, 1997.
In this interview Fred Hoyle discusses his childhood and growing up in Yorkshire; parental background and influences; early reading in science; early experience with literature; influence of Eddington's books; education at Cambridge; interest in mathematics; early interest in exploring cosmology after World War II; history of development of steady state model; influence of Dirac and preference for understanding mathematics first; thesis work with Dirac; personality of Dirac; history of work on nucleosynthesis in stars: the Cavendish Laboratory, nucleosynthesis in supernovae, carbon producti
This interview discusses John Huchra's childhood interest in science and early reading in science; education at Massachusetts Institute of Technology (MIT); education at California Institute of Technology (Caltech); move from theory to experiment at Caltech; importance of politics and Vietnam War in choosing an area of science; work on the Palomar supernova search; wide range of courses at Caltech; what questions should be asked in science; early experience with telescopes and observational astronomy; hands-on experience in astronomy; work on comets; work on galaxies; introduction to cosmol
Theoretical physicist. Undergraduate work at Princeton University, graduate work at Stanford University in the early 1980s, where he studied core collapse, Type II supernovae, using them as distance indicators using the Expanding Atmosphere Method. From the mid 1980s to the mid 1990s, he criticized those who would use supernovae as distance indicators. He is the author of the cosmology textbook, First Principles of Cosmology, published in 1997. Was a senior researcher at University of Massachusetts at Amherst when discovery came out in 1998.
Graduate work at U. C. Berkeley, starting in 1991, joined SCP in 1992, when it was called the High-z Search. On the discovery of group’s first supernova, 1992BG, at the Isaac Newton Telescope, and concomitant paper. Kim collaborated with Ivan Small and Matthew Kim to write IDL, the supernova search, analysis, and slice plot display software. That software has been converted to a C++ version in use now, for instance with the Hubble Space Telescope. Second batch of supernovae, approximately five found, at INT.
Robert Kirshner (of the High-z Team) is Clowes Professor of Science at Harvard University and the author of The Extravagant Universe: Exploding Stars, Dark Energy, and the Accelerating Cosmos a book that deals directly with the topic of this interview, and which includes the story of supernova cosmology with a first-hand account of Kirshner’s personal contribution.
