Ákos Szölgyén

PhD student

Supervisor: Bence Kocsis, (2023)

Biography:

Ákos is a PhD student in the Particle Physics and Astronomy program of the Doctoral School of Physics (2017 - ). He is a member of GalNUC Astrodynamics and Statistical Mechanics Research Group which is funded by an ERC Starting Grant and led by Bence Kocsis. His research interest focuses on the physics of black holes, stellar dynamics of galactic nuclei and globular clusters and gravitational-wave astrophysics. In his PhD thesis, he investigates the dynamics and statistical physics of black hole populations in galactic nuclei and globular clusters. He wrote his MSc thesis about the statistical stability and formation of
black hole disks in galactic nuclei under the supervision of Bence Kocsis.

During his undergraduate studies (2013 - 2017), Ákos was a member of Eötvös Gravity Research Group which is the Hungarian partner in the LIGO Scientific Collaboration at Eötvös University. As a member of the LIGO Collaboration, Ákos was working on a global optimization of gravitational-wave detector networks with supervisor Peter Raffai. He summarized this work in a BSc thesis and in a refereed paper which was published in 2017. During LIGO's first observing run, Ákos was among those collaboration advocates who were responsible for monitoring LIGO data quality and gravitational wave detection alerts. He participated in several working seminars, telecons, meetings, and I gave numerous introductory talks on gravitational waves. He was also responsible for developing the Hungarian LIGO website.

In 2017, he was awarded by the New National Excellence Program of the Ministry of Human Capacities; in 2016, by a Conference attendance support of COST Action MP 1405, and by the National Excellence Program's scholarship of the Ministry of Human Capacities, he won the Scholarship of the Talent Management Council of Eötvös Loránd University in 2015.

Ákos taught laboratory courses, and vector algebra & analysis course for first year physics BSc students.
