Abstract

Interview with Alan Dressler, Astronomer Emeritus at The Carnegie Institute for Science Observatories. He describes his current focus on the James Webb Telescope and he conveys concern for a "post-reality" political environment that has taken a grip on American politics. He recounts his upbringing in Cincinnati, and how his curiosity about how things worked naturally pulled him toward astronomical interests. Dressler discusses his undergraduate education at UC Berkeley and his decision to pursue a PhD in the newly created Department of Astronomy at UC Santa Cruz. He describes the importance of the Lick Observatory for his research under the direction of Joe Wampler, and how Jim Peebles gave this thesis project a "seal" of approval. Dressler describes the origins of the Dressler Relation in his study of the morphology of galaxies and the density of their environment, and he describes the opportunities leading to his postdoctoral appointment at Carnegie. He explains the history of the Caltech-Carnegie partnership in astronomy, and he describes working with Allan Sandage and Jim Gunn. Dressler emphasizes the revolutionary effect the Hubble Telescope imparted to the field, and he discusses his time as a Las Campanas fellow. He describes how his work on galaxy formation fed into larger questions about the origins of the universe and the broader philosophical implication of our understanding of Earth's place in the universe. Dressler explains the Great Attractor Model and the state of play in black hole research in the 1980s, and he describes why he did not need to "see" an image of black holes to be convinced of their existence. He narrates the origins of the Association of Universities for Research and Astronomy, and the drama surrounding the repair of the Hubble. Dressler describes presenting the HST & Beyond report to NASA administrator Dan Goldin, and he discusses the natural progression for his work on the NASA Origins program. He discusses his subsequent focus on the Magellan Telescope and the EOS Decadal Survey. At the end of the interview, Dressler reflects on the strides made in galaxy formation research over the course of his career, and he conveys pride in playing a role in science, for which he appreciated since youth as a field that offered limitless opportunities to improve the world.

Abstract

Interview with Philip Phillips, Professor of Physics at the University of Illinois Urbana-Champaign. Phillips recounts his early childhood in Tobago and the circumstances of his family’s move to Washington State. He conveys his bemusement at having no degree in physics, as his graduate work at the University of Washington was in chemistry, where he completed a PhD on fluorescence lifetimes in single molecules under the direction of Ernest Davidson, and where David Boulware provided the intellectual entrée to physics. Phillips explains the opportunities that allowed him to pursue postdoctoral work at Berkeley and learning RG from Orlando Alvarez. He describes his first faculty position in the chemistry department at MIT, some of the research challenges given that his primary interests were in physics, and his feeling that MIT was at the time not a very inclusive atmosphere. Phillips discusses his work on the random dimer model and the happenstance opportunity that led to his faculty appointment at Illinois. He explains getting involved with the National Society of Black Physicists and his efforts to make the department more diverse. Phillips describes the research that was recognized by the Edward Bouchet award and why Tony Leggett is among the few physicists who truly understands Mottness. He discusses advances in strongly coupled electron systems and he explains why he dislikes the term condensed matter and prefers solid-state. Phillips reflects on STEM’s response to the racial strife over the past year, and he discusses his current interests in pseudogaps. At the end of the interview, Phillips conveys his dream to solve the Hubbard model and to make advances in high-Tc research.

Abstract

Interview with Kevin Lesko, Senior Physicist at Lawrence Berkeley National Lab and former Spokesperson for LUX-ZEPLIN (LZ), an international collaboration searching for dark matter. Lesko explains why so many different kinds of physicists are involved in dark matter searches and how theorists have provided guidance for experimental and observational work to understand dark matter. He recounts his upbringing in northern California, the scientific influence of his parents and older siblings, and his decision to attend Stanford, where he worked on a tandem Van De Graaff in the nuclear physics lab. Lesko discusses his graduate work at the University of Washington, where he worked under the direction of Bob Vandenbosch on nuclear fission research, and he describes his postdoctoral appointment at Argonne, where he pursued experiments in nuclear fusion and neutrino physics. He explains his decision to join the staff at Berkeley Lab and how his interests centered increasingly on astrophysics with the Sudbury Neutrino Observatory. Lesko discusses his collaborations in Japan and KamLAND’s discovery of the absolute measurement of neutrino oscillations and the origins of the Homestake collaboration. He describes the transition of support for Homestake from the NSF to the DOE and he explains his entrée to the LUX collaboration and the reasons for the merger with ZEPLIN. Lesko explains how LZ needs to be ready to detect dark matter either as a singularity or is comprised of multiple components, and he considers what it might look like for dark matter to be detected. He recounts LZ’s success in ruling out dark matter candidates and he reflects on LBNL serving as a home base while his collaborative research has always been far-flung. At the end of the interview, Lesko considers what we have learned about the universe as a result of LZ, and why mystery and curiosity will continue to drive the field forward.

Interview with Roger Blandford, the Luke Blossom Professor at the School of Humanities and Sciences at Stanford University and Professor of Physics at SLAC. He discusses his current work developing alternate understandings of the Event Horizon Telescope image, on fast radio bursts, and on the notion that handedness has astrophysical origins. Blandford describes the history of cosmology as a respectable discipline within physics, and he credits the rise of VLBI in the 1960s and 1970s for demonstrating the evidence of black holes. He recounts his childhood in England, his early interests in science, and his education at Cambridge, where his thesis research on accretion discs and radio sources was supervised by Martin Rees. Blandford discusses his postdoctoral work on astrophysical particle acceleration and plasma and QED processes in pulsars and a formative visit to the Institute for Advanced Study and to Berkeley. He describes his initial impressions of Caltech where he joined the faculty and where he worked closely with Roman Znajek, and he explains the distinctions between radio jets and relativistic jets. Blandford explains his reasons for moving to Stanford to set up the Kavli Institute and he describes his involvement with the Astronomy and Astrophysics Decadal Survey. At the end of the interview, Blandford contends that the most exciting developments in the field have been on exoplanet research, why the possibilities in astrobiology give him cause for optimism, and why the concept that astronomical discovery arrives as “logically unscripted” resonates with him.
