From Birth to Chirp – Astrophysics of Massive Stars as Gravitational Wave Progenitors.

Abstract: How did they form?’ is a question many asked when LIGO announced the first direct detection of gravitational waves originating from two surprisingly heavy stellar-mass black holes. With masses of about 30 solar masses each, they outweighed all of the known black holes known from X-ray binaries. Now, four years after the first detection, alerts of new triggers come in at a rate of almost one per week. The analysis of the first eleven events has been published and we learned that the first system was not exceptional: the majority of detected events involve heavy black holes. In parallel, classical telescopes have been revolutionizing our understanding of the properties of young massive stars.

De Mink Group September 2019

5 Sep

Time for an update with all new faces of our cross Atlantic group. In (crimson) red all those that are Harvard based and in orange all those that are in Amsterdam.

Cross Atlantic Move

9 Aug

August 1, 2019, I started at Harvard University. I keep being affiliated with the University of Amsterdam. Incredibly excited to start a new (transatlantic) group.

Manos Zapartas awarded the Swiss Government Excellence Prize Fellowship

15 May
Dr. E. (Manos) Zapartas

Manos Zapartas is a very recent BinCosmos PhD graduate, who only left our group a few months ago for Geneva observatory. We are very excited to share that he has been awarded the competitive Swiss Government Excellence Fellowship. This allows him to pursue his research on the final fate of massive binary stars. He will do so as a member of the group of dr. Tassos Fragos, who recently joined Geneva Observatories last year as an assistant professor.

Postdoc Athira Menon wins National Famelab competition

15 May

Group member Athira Menon, postdoc in the BinCosmos group, won the Dutch final of FameLab on 9 May. FameLab is a pitch competition for young researchers, in which they have only three minutes to explain their research to the general public.  By winning the national final, she won a trip to Cheltenham, England, to compete at the annual Cheltenham Science Festival (June 4-9) against 24 other FameLab winners from around the world.

Elected as member of the Dutch Young Academy of Sciences

24 Mar

De Mink is one of the ten new members of the Dutch National Young academy of sciences, installed March 21, 2019. The Academy unites Dutch talented scientists across all academic disciplines that obtained their Ph.D. less than ten years ago. In addition to having an outstanding track record, they share a strong interest in science policy and science communication. Membership is for five years. Read about the profiles of the ten new members here.

Preprint: Pulsational pair-instability supernovae in very close binaries

4 Jan

Anticipating new gravitational wave detections of heavy binary black holes, Pablo Marchant (CIERA) together with Bincosmos group members Mathieu Renzo and Rob Farmer’s explore the effects of pulsations experienced by the most massive stars. Find a preview here.

“Pulsational pair-instability supernovae in very close binaries” by Pablo Marchant, Mathieu Renzo,Robert Farmer, Kaliroe M. W. Pappas, Ronald E. Taam, Selma de Mink, and Vassiliki Kalogera.
