About me

Mathieu Renzo I am an assistant professor in the Astronomy Department and Steward Observatory at the University of Arizona, in Tucson. My interest in astronomy comes from the wide range of physical processes occurring astronomical context. I focus mostly on stellar astrophysics, and in particular massive stars, binary evolution, and stellar explosions. My research interest include stellar kinematics (runaway, "walkaway", and hyper-velocity stars), core-collapse and (pulsational) pair-instability supernovae, nuclear astrophysics, X-ray binaries, time-domain and gravitational-wave astronomy. I mainly use analytical and numerical simulations to understand massive star evolution, their explosions, and how they interact in binary systems. I use both detailed stellar structure and evolution models (e.g., with MESA, and rapid population synthesis (e.g., with binary c or COSMIC). I also simulate the light coming from explosions (e.g., with SNEC) and I am learning to run multidimensional hydrodynamic simulations (with ATHENA++).

Short Bio

I studied at the University of Pisa for my bachelor and master's degrees. I then moved to Amsterdam for my PhD, to work with Selma de Mink. In 2017, I spent one semester as KITP graduate fellow at UCSB, and I completed my PhD in 2019. After that I moved to New York city where I spent four years between the Center for Computational Astrophysics of the Flatiron Institute and Columbia University.


Project on 3D radiation hydrodynamic simulations with ATHENA++ of the onset of mass transfer in a binary available!
