Searching for Systematics in Forward Modeling Sunyaev-Zeldovich Profiles

Understand

The Sunyaev-Zeldovich thermal (tSZ) and kinetic (kSZ) effects can be used to constrain the thermodynamic properties of pressure and density, respectively, of galaxies and their surrounding regions.

• As SZ observations continue to improve, it is important to understand any modeling systematics when inferring properties from the data.
• Thus, a pipeline to forward model observed SZ profiles was developed called Mop-c-GT.
• Previous studies have used this repository to create modeled SZ profiles by selecting halos from the IllustrisTNG simulation and found significant differences between the simulated profiles and those recently measured by the Atacama Cosmology Telescope.
