A multi-simulation study of relativistic SZ temperature scalings in galaxy clusters and groups
Elizabeth Lee, Dhayaa Anbajagane, Priyanka Singh +6
The Sunyaev-Zeldovich (SZ) effect is a powerful tool in modern cosmology. With future observations promising ever improving SZ measurements, the relativistic corrections to the SZ…
Cosmology dependency of halo masses and concentrations in hydrodynamic simulations
Antonio Ragagnin, Alexandro Saro, Priyanka Singh +1
We employ a set of Magneticum cosmological hydrodynamic simulations that span over different cosmologies, and extract masses and concentrations of all well-resolved haloes bet…
Cosmology dependence of galaxy cluster scaling relations
Priyanka Singh, Alex Saro, Matteo Costanzi +1
The abundance of galaxy clusters as a function of mass and redshift is a well known powerful cosmological probe, which relies on underlying modelling assumptions on the mass-observ…
Probing the circumgalactic baryons through cross-correlations
Priyanka Singh, Subhabrata Majumdar, Biman B. Nath +2
We study the cross-correlation of distribution of galaxies, the Sunyaev-Zel'dovich (SZ) and X-ray power spectra of galaxies from current and upcoming surveys and show these to be e…
CMB distortion from circumgalactic gas
Priyanka Singh, Biman B. Nath, Subhabrata Majumdar +1
We study the Sunyaev-Zel'dovich (SZ) distortion of the cosmic microwave background radiation (CMBR) from extensive circumgalactic gas (CGM) in massive galactic halos. Recent observ…
