Gas-phase metallicity break radii of star-forming galaxies in IllustrisTNG
Alex M. Garcia, Paul Torrey, Z. S. Hemler +6
We present radial gas-phase metallicity profiles, gradients, and break radii at redshift from the TNG50-1 star-forming galaxy population. These metallicity profiles are…
Tracing the hot spot motion using the next generation Event Horizon Telescope (ngEHT)
Razieh Emami, Paul Tiede, Sheperd S. Doeleman +19
We propose to trace the dynamical motion of a shearing hot spot near the SgrA* source through a dynamical image reconstruction algorithm, StarWarps. Such a hot spot may form as the…
Morphological signatures of mergers in the TNG50 simulation and the Kilo-Degree Survey: the merger fraction from dwarfs to Milky Way-like galaxies
Alejandro Guzmán-Ortega, Vicente Rodriguez-Gomez, Gregory F. Snyder +2
Using the TNG50 cosmological simulation and observations from the Kilo-Degree Survey (KiDS), we investigate the connection between galaxy mergers and optical morphology in the loca…
Active galactic nucleus jet feedback in hydrostatic halos
Rainer Weinberger, Kung-Yi Su, Kristian Ehlert +8
Feedback driven by jets from active galactic nuclei is believed to be responsible for reducing cooling flows in cool-core galaxy clusters. We use simulations to model feedback from…
The merger and assembly histories of Milky Way- and M31-like galaxies with TNG50: disk survival through mergers
Diego Sotillo-Ramos, Annalisa Pillepich, Martina Donnari +6
We analyze the merger and assembly histories of Milky Way (MW) and Andromeda (M31)-like galaxies to quantify how, and how often, disk galaxies of this mass can survive recent major…
Orbital and Radiative Properties of Wandering Intermediate-Mass Black Holes in the ASTRID Simulation
Emma Jane Weller, Fabio Pacucci, Yueying Ni +4
Intermediate-Mass Black Holes (IMBHs) of are commonly found at the center of dwarf galaxies. Simulations and observations convincingly show that a sizable po…
The MillenniumTNG Project: Inferring cosmology from galaxy clustering with accelerated N-body scaling and subhalo abundance matching
Sergio Contreras, Raul E. Angulo, Volker Springel +11
We introduce a novel technique for constraining cosmological parameters and galaxy assembly bias using non-linear redshift-space clustering of galaxies. We scale cosmological N-bod…
The MillenniumTNG Project: The galaxy population at
Rahul Kannan, Volker Springel, Lars Hernquist +11
The early release science results from have yielded an unexpected abundance of high-redshift luminous galaxies that seems to be in tension with current theories of…
Unraveling Twisty Linear Polarization Morphologies in Black Hole Images
Razieh Emami, Angelo Ricarte, George N. Wong +23
We investigate general relativistic magnetohydrodynamic simulations (GRMHD) to determine the physical origin of the twisty patterns of linear polarization seen in spatially resolve…
Modeling globular clusters in the TNG50 simulation: predictions from dwarfs to giants
Jessica E. Doppel, Laura V. Sales, Dylan Nelson +9
We present a post-processing catalog of globular clusters (GCs) for the most massive groups and clusters in the TNG50 simulation of the IlllustrisTNG project (virial masses $M…
Origin and evolution of ultra-diffuse galaxies in different environments
Jose A. Benavides, Laura V. Sales, Mario. G. Abadi +3
We study the formation of ultra-diffuse galaxies (UDGs) using the cosmological hydrodynamical simulation TNG50 of the Illustris-TNG suite. We define UDGs as dwarf galaxies in the s…
The locations of features in the mass distribution of merging binary black holes are robust against uncertainties in the metallicity-dependent cosmic star formation history
