How does a galaxy's quenching probability depend on its black hole's mass?
Antonio J. Porras-Valverde, John C. Forbes
We develop a parametric toy model to explore how black hole mass scatter and the dependence of the quenching probability per unit time on black hole mass, parameterize…
The size of 3I/ATLAS from non-gravitational acceleration
John C. Forbes, Harvey Butler
The third macroscopic interstellar object detected in the solar system recently passed through perihelion, with the best-fitting models of its trajectory now featuring non-gravitat…
Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances*
Rohan Rahatgaonkar, Juan Pablo Carvajal, Thomas H. Puzia +25
We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025~N1) from to ~au using X-shooter (300--550\,nm, ) and UVES (opt…
On the signature of black holes on the quenched stellar mass function
Antonio J. Porras-Valverde, John C. Forbes
As star-forming galaxies approach or exceed a stellar mass around , they are increasingly likely to be quenched in a process generically called mass quenching. Cen…
Towards Implementation of the Pressure-Regulated, Feedback-Modulated Model of Star Formation in Cosmological Simulations: Methods and Application to TNG
Sultan Hassan, Eve C. Ostriker, Chang-Goo Kim +12
Traditional star formation subgrid models implemented in cosmological galaxy formation simulations, such as that of Springel & Hernquist (2003, hereafter SH03), employ adjustable p…
Why do semi-analytic models predict higher scatter in the stellar mass-halo mass relation than cosmological hydrodynamic simulations?
Antonio J. Porras-Valverde, John C. Forbes, Rachel S. Somerville +4
Semi-analytic models (SAMs) systematically predict higher stellar-mass scatter at a given halo mass than hydrodynamical simulations and most empirical models. Our goal is to invest…
Gas Morphology of Milky Way-like Galaxies in the TNG50 Simulation: Signals of Twisting and Stretching
Thomas K. Waters, Colton Peterson, Razieh Emami +9
We present an in-depth analysis of gas morphologies for a sample of 25 Milky Way-like galaxies from the IllustrisTNG TNG50 simulation. We constrain the morphology of cold, warm, ho…
