The nature of post-starburst galaxies: real deal or masquerading impostors?

Elia Cenci, ROBERT J. FELDMANN, Sarah Wellons, Jindra Gensior et autres

ABSTRACT Post-starburst galaxies (PSBs) are a population of galaxies with spectral and photometric features indicative of rapid quenching following a recent starburst. The origin and nature of PSBs are currently debated. For example, a number of observed PSBs unexpectedly host substantial molecular …

Unveiling the dark Universe with H i and EMBER-2

Mauro Bernardini, ROBERT J. FELDMANN, Daniel Anglés‐Alcázar, Philipp Denzel et autres

ABSTRACT Next-generation radio telescopes will provide unprecedented data volumes of the neutral hydrogen (H i) distribution across cosmic time. The spatial and kinematic distribution of H i is a biased tracer of the underlying matter field, and as such contains information on …

EMBER-2: emulating baryons from dark matter across cosmic time with deep modulation networks

Mauro Bernardini, ROBERT J. FELDMANN, Jindra Gensior, Daniel Anglés-Alcázar et autres

Galaxy formation is a complex problem that connects large-scale cosmology with small-scale astrophysics over cosmic time-scales. Hydrodynamical simulations are the most principled approach to model galaxy formation, but have large computational costs. Recently, emulation techniques based on convolutional neural networks (CNNs) have …

The H i covering fraction of Lyman Limit Systems in FIRE haloes

L. Tortora, ROBERT J. FELDMANN, Mauro Bernardini, Claude‐André Faucher‐Giguère

ABSTRACT Atomic hydrogen (H i) serves a crucial role in connecting galactic-scale properties such as star formation with the large-scale structure of the Universe. While recent numerical simulations have successfully matched the observed covering fraction of H i near Lyman Break Galaxies …

Inflow and outflow properties, not total gas fractions, drive the evolution of the mass–metallicity relation

Luigi Bassini, ROBERT J. FELDMANN, Jindra Gensior, Claude‐André Faucher‐Giguère et autres

ABSTRACT Observations show a tight correlation between the stellar mass of galaxies and their gas-phase metallicity (MZR). This relation evolves with redshift, with higher redshift galaxies being characterized by lower metallicities. Understanding the physical origin of the slope and redshift evolution of …

Starburst-induced Gas–Star Kinematic Misalignment

Elia Cenci, ROBERT J. FELDMANN, Jindra Gensior, James S. Bullock et autres

Abstract A kinematic misalignment of the stellar and gas components is a phenomenon observed in a significant fraction of galaxies. However, the underlying physical mechanisms are not well understood. A commonly proposed scenario for the formation of a misaligned component requires any …
