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…
Probing plasma composition with the next generation Event Horizon Telescope (ngEHT)
Razieh Emami, Richard Anantua, Angelo Ricarte +15
We explore the plasma matter content in the innermost accretion disk/jet in M87* as relevant for an enthusiastic search for the signatures of anti-matter in the next generation of…
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…
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…
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…
Galactic angular momentum in the IllustrisTNG simulation -- I. Connection to morphology, halo spin, and black hole mass
Vicente Rodriguez-Gomez, Shy Genel, S. Michael Fall +9
We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta () of 12,000 central galaxies at in a full cosmol…
