Hawking Radiation from non-evaporating primordial black holes cannot enable the formation of direct collapse black holes
Jonathan Regan, Marios Kalomenopoulos, Kelly Kosmo O'Neil
The formation of supermassive black holes (SMBHs) in the early Universe is a subject of significant debate. In this study, we examine whether non-evaporating primordial black holes…
The Local Volume Database: a library of the observed properties of nearby dwarf galaxies and star clusters
Andrew B. Pace
I present the Local Volume Database (LVDB), a catalog of the observed properties of dwarf galaxies and star clusters in the Local Group and Local Volume. The LVDB includes position…
The Impact of Star Formation and Feedback Recipes on the Stellar Mass and Interstellar Medium of High-Redshift Galaxies
Harley Katz, Martin P. Rey, Corentin Cadiou +2
We introduce MEGATRON, a new galaxy formation model for cosmological radiation hydrodynamics simulations of high-redshift galaxies. The model accounts for the non-equilibrium chemi…
The molecular gas content throughout the low-z merger sequence
Mark T. Sargent, S. L. Ellison, J. T. Mendel +5
Exploiting IRAM 30m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50%, a mildly higher CO excitation, and standar…
The impact of feedback on the evolution of gas density profiles from galaxies to clusters: a universal fitting formula from the Simba suite of simulations
Daniele Sorini, Sownak Bose, Romeel Davé +1
The radial distribution of gas within galactic haloes is connected to the star formation rate and the nature of baryon-driven feedback processes. Using six variants of the hydrodyn…
On the Nature of the C IV-bearing Circumgalactic Medium at z~1
Suyash Kumar, Hsiao-Wen Chen, Zhijie Qu +5
This paper presents a detailed study of the physical properties of seven C IV absorbers identified at z_abs = 0.68-1.28 along the line of sight toward QSO PG 1522+101 (z_QSO = 1.33…
