Three-point intrinsic alignments of dark matter halos in the IllustrisTNG simulation
Susan Pyne, Ananth Tenneti, Benjamin Joachimi
We use the IllustrisTNG suite of cosmological simulations to measure intrinsic alignment (IA) bispectra of dark matter subhalos between redshifts 0 and 1. We decompose the intrinsi…
Group-scale intrinsic galaxy alignments in the Illustris-TNG and MassiveBlack-II simulations
Ananth Tenneti, Thomas D. Kitching, Benjamin Joachimi +1
We study the alignments of satellite galaxies, and their anisotropic distribution, with respect to location and orientation of their host central galaxy in MassiveBlack-II and Illu…
On the possibility of Baryon Acoustic Oscillation measurements at redshift with the Roman Space Telescope
Siddharth Satpathy, Zhaozhou An, Rupert A. C. Croft +5
The Nancy Grace Roman Space Telescope (RST), with its field of view and high sensitivity will make surveys of cosmological large-scale structure possible at high redshifts. We inve…
Cosmic variance of galaxies: Prediction from BlueTides
Aklant K. Bhowmick, Rachel S. Somerville, Tiziana DiMatteo +3
In the coming decade, a new generation of telescopes, including JWST and WFIRST, will probe the period of the formation of first galaxies and quasars, and open up the last frontier…
The evolution of galaxy intrinsic alignments in the MassiveBlack II universe
Aklant K Bhowmick, Yingzhang Chen, Ananth Tenneti +2
We investigate the redshift evolution of the intrinsic alignments (IA) of galaxies in the \texttt{MassiveBlackII} (MBII) simulation. We select galaxy samples above fixed subhalo ma…
Impact of Baryonic Physics on Intrinsic Alignments
Ananth Tenneti, Nickolay Y. Gnedin, Yu Feng
We explore the effects of specific assumptions in the subgrid models of star formation and stellar and AGN feedback on intrinsic alignments of galaxies in cosmological simulations…
