Galaxy evolution in the post-merger regime. V - Atomic gas evolution traced by ALFALFA stacks
Sara L. Ellison, Manasvee Saraf, Leonardo Ferreira +4
(Abridged) In this work, we investigate the role of atomic hydrogen (HI) gas in the galaxy merger lifecycle. In order to both identify galaxies in mergers, as well as to predict th…
Extending the Stellar-to-Halo Mass Relation to Dwarf Galaxies with DESI DR1
Z. Shao, Y. Zu, A. Salcedo +51
Constraining the dark matter halos of the smallest galaxies offers fundamental insights into the nature of dark matter and stellar feedback. Using the Dark Energy Spectroscopic Ins…
Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years
Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49
The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
Dwarf galaxy halo masses from spectroscopic and photometric lensing in DESI and DES
Helena Treiber, Alexandra Amon, Risa H. Wechsler +46
We present the most precise and lowest-mass weak lensing measurements of dwarf galaxies to date, enabled by spectroscopic lenses from the Dark Energy Spectroscopic Instrument (DESI…
WALLABY Pilot Survey: kNN identification of perturbed galaxies through HI morphometrics
B. W. Holwerda, Helga Dénes, J. Rhee +11
Galaxy morphology in stellar light can be described by a series of "non-parametric" or "morphometric" parameters, such as concentration-asymmetry-smoothness, Gini, , and Se…
xGASS: The scatter of the HI-halo mass relation of central galaxies
Manasvee Saraf, Luca Cortese, O. Ivy Wong +3
Empirical studies of the relationship between baryonic matter in galaxies and the gravitational potential of their host halos are important to constrain our theoretical framework f…
HI absorption associated with Norma's brightest cluster galaxy
Manasvee Saraf, O. Ivy Wong, Luca Cortese +1
ESO 137-G006 is the brightest cluster galaxy (BCG) of the cool-core and dynamically young Norma cluster. We discover an atomic hydrogen (HI) absorption line associated with this BC…
