It is my sad duty to pass on the sad news of the death of Sergei Shandarin, who passed away yesterday at the age of 77. He had been suffering from cancer for some time and had been undergoing chemotherapy, alas to no avail. Last week he was moved onto palliative care and we knew he would soon be leaving us. I was going to post something last night when I heard that he had died, but I just couldn’t find the words. I send my deepest condolences to his family, friends and colleagues who are grieving.
(The picture on the left shows Sergei in 2006; I’m grateful to John Peacock for letting me use it here.)
Sergei Fyodor Shandarin was born in 1947 and gained his PhD at the Moscow Institute of Physics and Technology in 1974. He was a student of the great physicist Yakov Borisovich Zeldovich (whom I blogged about here). Sergei moved to the USA in 1991 to take up a Professorship at the University of Kansas, in Lawrence, where he remained until his retirement. More recently he and his wife Vika moved to Toronto to be closer to his daughter Anya and their grandchildren.
Sergei’s main research interests were the dynamics and statistics of the “Cosmic Web” – the supercluster- void network in spacial distribution of galaxies. In particular, he was interested in nonlinear dynamics of gravitational instability, which is the major mechanism for the formation of a large variety of objects in the universe, and in geometrical and topological statistical descriptors of the distribution of mass and galaxies in space.
These topics overlap considerably with my own and I was delighted to have the opportunity to work with Sergei in 1992 when I was invited by Adrian Melott as a visitor to Lawrence fro about a month. My first impression of Sergei was that he was a bit scary – in that typical Russian physicist sort of way – but I soon discovered that, beneath his initially rather fierce demeanour, he was actually a kind and friendly person with a fine sense of humour. I remember that research visit very well, in fact, not only because of Adrian’s and Sergei’s hospitality, but also because the project we did together went so well that we not only completed the research, but I returned to London with a completed manuscript; the paper that resulted was published in early 1993.
After that I kept in touch with Sergei mainly at conferences. Last night after I heard the news that he has passed away I brought a box of old photographs down from the loft and rummaged around for some pictures. Here are two from a meeting in India in 1994, in which you can see Sergei very much in the centre of things:
The picture on the left shows: (standing, L to R) Francis Bernardeau, Paolo Catelan, Sergei, ?*, Paul R. Shapiro; (crouching) Enzo Branchini and Bernard Jones. The picture on the right has the addition of, among others, Varun Sahni (between Paul Shapiro and Bernard Jones), Dick Bond (with his arm on Sergei’s shoulder) and Sabino Matarrese (front left); I’m on the right of the front row. I remember these pictures were taken on an excursion from Pune to see the historic caves and temples at Ajanta and Ellora.
(*I think the unidentified person might be Lars Hernquist, but I’m not sure: I’d be grateful for any information.)
I also particular remember meeting up with Sergei at meetings in Los Angeles, Nice, Valencia (the meeting at which the first picture was taken). and most recently in Estonia (for a meeting to celebrate the centenary of the birth of Zel’dovich). He was always up for scientific discussions, but also liked to relax with a drink or several; he also liked to watch football.
Sergei was a wonderful scientist as well as a warm and generous human being who was held in a very high regard by the cosmological community worldwide. We will all miss him terribly.
Rest in peace, Sergei Fyodor Shandarin (1947-2025)
