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…
SDSS-IV MaNGA: Cannibalism Caught in the Act -- on the Frequency of Occurrence of Multiple Cores in Brightest Cluster Galaxies
Yun-Hsin Hsu, Yen-Ting Lin, Song Huang +16
Although it is generally accepted that massive galaxies form in a two-phased fashion, beginning with a rapid mass buildup through intense starburst activities, followed by primaril…
High and low Sérsic index bulges in Milky Way- and M31-like galaxies: origin and connection to the bar with TNG50
Ignacio D. Gargiulo, Antonela Monachesi, Facundo A. Gómez +8
We study bulge formation in MW/M31-like galaxies in a -cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose we use TNG50, a s…
Supermassive black holes in cosmological simulations II: the AGN population and predictions for upcoming X-ray missions
Melanie Habouzit, Rachel S. Somerville, Yuan Li +13
In large-scale hydrodynamical cosmological simulations, the fate of massive galaxies is mainly dictated by the modeling of feedback from active galactic nuclei (AGN). The amount of…
Cosmic metal density evolution in neutral gas: insights from observations and cosmological simulations
Robert M. Yates, Celine Peroux, Dylan Nelson
We contrast the latest observations of the cosmic metal density in neutral gas () with three cosmological galaxy evolution simulations: L-GALAXIES 2020, TNG100, an…
The building up of observed stellar scaling relations of massive galaxies and the connection to black hole growth in the TNG50 simulation
S. Varma, M. Huertas-Company, A. Pillepich +7
[abridged] We study how mock-observed stellar morphological and structural properties of massive galaxies are built up between and in the TNG50 cosmological simulatio…
