On the formation of massive quiescent galaxies with diverse morphologies in the TNG50 simulation
Minjung Park, Sandro Tacchella, Erica J. Nelson +7
Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using th…
Turning AGN bubbles into radio relics with sloshing: modeling CR transport with realistic physics
John ZuHone, Kristian Ehlert, Rainer Weinberger +1
Radio relics are arc-like synchrotron sources at the periphery of galaxy clusters, produced by cosmic-ray electrons in a G magnetic field which are believed to have been (re-)ac…
AGN and Star Formation at Cosmic Noon: Comparison of Data to Theoretical Models
Jonathan Florez, Shardha Jogee, Yuchen Guo +14
In theoretical models of galaxy evolution, AGN and star formation (SF) activity are closely linked and AGN feedback is routinely invoked to regulate galaxy growth. In order to cons…
Impact of gas spin and Lyman-Werner flux on black hole seed formation in cosmological simulations: implications for direct collapse
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +5
Direct collapse black holes~(BH) are promising candidates for producing massive quasars, but their formation requires fine-tuned conditions. In this work, we use cosmo…
X-ray bubbles in the circumgalactic medium of TNG50 Milky Way- and M31-like galaxies: signposts of supermassive black hole activity
Annalisa Pillepich, Dylan Nelson, Nhut Truong +5
The TNG50 cosmological simulation produces X-ray emitting bubbles, shells, and cavities in the circumgalactic gas above and below the stellar disks of Milky Way- and Andromeda-like…
Impact of gas based seeding on supermassive black hole populations at
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +6
Deciphering the formation of supermassive black holes~(SMBHs) is a key science goal for upcoming observational facilities. In most theoretical channels proposed so far, the seed fo…
Quenching, Mergers and Age Profiles for z=2 Galaxies in IllustrisTNG
Debosmita Pathak, Sirio Belli, Rainer Weinberger
Using the IllustrisTNG cosmological galaxy formation simulations, we analyze the physical properties of young quiescent galaxies at z=2 with stellar masses above 10^10.5 solar mass…
Reconstructing the Last Major Merger of the Milky Way with the H3 Survey
Rohan P. Naidu, Charlie Conroy, Ana Bonaca +8
Several lines of evidence suggest the Milky Way underwent a major merger at z~2 with a galaxy known as Gaia-Sausage-Enceladus (GSE). Here we use H3 Survey data to argue that GSE en…
Spatially Resolved Star Formation and Inside-out Quenching in the TNG50 Simulation and 3D-HST Observations
Erica J. Nelson, Sandro Tacchella, Benedikt Diemer +21
We compare the star forming main sequence (SFMS) -- both integrated and resolved on 1kpc scales -- between the high-resolution TNG50 simulation of IllustrisTNG and observations fro…
The Evolutionary Pathways of Disk-, Bulge-, and Halo-dominated Galaxies
Min Du, Luis C. Ho, Victor P. Debattista +4
To break the degeneracy among galactic stellar components, we extract kinematic structures using the framework described in Du et al. (2019, 2020). For example, the concept of stel…
The abundance of satellites around Milky Way- and M31-like galaxies with the TNG50 simulation: a matter of diversity
Christoph Engler, Annalisa Pillepich, Anna Pasquali +9
We study the abundance of satellite galaxies around 198 Milky Way- (MW) and M31-like hosts in TNG50, the final instalment in the IllustrisTNG suite of cosmological magnetohydrodyna…
