Biography

I’m a postdoctoral researcher located at the Kapteyn Astronomical Institute at the University of Groningen. I’m also affiliated with, and funded by, ARCO at the Open University of Israel.

I’m interested in understanding physics processes of the gas in galaxy clusters and filaments such as turbulence, shocks and accretion through cosmological simulations with the aim to help understand current and future observations.

You can find my publications below or on NASA/ADS as well as my talks, posters and outreach in my CV.

Interests
  • Gas physics galaxy clusters environments and filaments

Studying gas physics in the simulated Virgo cluster

In this project, gathering multiple works, I use a simulated replica of the Virgo cluster to study the gas physics in and around this complex galaxy cluster. This case study serves as a great pathfinder in the scope of the larger LOCALIZATION project.
