Very long baseline interferometry

Interview with Lev Gindilis, Russian astronomer and a pioneer of modern SETI research. Leonid Gurvits translated this interview in real-time. Gindilis discusses his studies in optical astronomy at Moscow State University. He describes how the work of his friend Nikolai Kardashev inspired him to switch his area of focus and join the radio astronomy department. Gindilis recounts helping to build the RATAN 600 telescope, as well as his work organizing meetings on SETI topics, including the First Soviet-American Conference on Communication with Extraterrestrial Intelligence in 1971. Gindilis reflects on the philosophical aspects of extraterrestrial communication, such as the question of mutual understanding. He discusses Kardashev’s investigations into CTA-21 and CTA-102 and the importance of the discovery of variability. The interview concludes with Gindilis’ reflections on international collaboration in SETI research and the effects of the Cold War.

Interview with Kenneth Kellermann, American astronomer at the National Radio Astronomy Observatory. The interview focuses on Kellermann’s role in the early development of very long baseline interferometry (VLBI), beginning in the 1960s. Kellermann goes into detail about the collaborations on VLBI between the American, Australian, and Swedish scientific communities. He also describes the informal exchanges he took part in with Russian scientists. Kellermann discusses the network of scientists from both the US and USSR that worked together on VLBI, and he speaks on his relationship with Iosif Shklovsky. The interview then shifts to Kellermann’s work on the search for extraterrestrial intelligence, beginning with his time in Australia. He talks about various SETI conferences, particularly the First Soviet-American Conference on Communication with Extraterrestrial Intelligence in 1971 in Byurakan. The interview concludes with Kellermann sharing his current thoughts on SETI and how the work has changed over time.
