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…
Controlled Experiments on Dark-Matter Halo Structure and Galaxy Morphology I: What Sets Galaxy Sizes?
Guangze Sun, Fangzhou Jiang, Jing Wang
The properties of galaxies are intricately linked to the characteristics of their host dark-matter haloes. We use a suite of controlled simulations of isolated galaxies to quantify…
EMBERS I: Low redshift post-starburst galaxies are frequently depleted in molecular gas relative to star forming progenitors
Ben F. Rasmussen, María Jesús Jiménez-Donaire, Sara L. Ellison +10
The cold gas content of post-starburst galaxies (PSBs) provides important insight into the mechanisms that drive rapid quenching, but a multiphase assessment of both the atomic and…
Low redshift post-starburst galaxies host abundant HI reservoirs
Sara L. Ellison, Qifeng Huang, Dong Yang +8
Studying the gas content of post-starburst (PSB) galaxies can provide valuable clues regarding the process of fast quenching. Although previous works have studied the molecular gas…
WALLABY Pilot Survey: Star Formation Enhancement and Suppression in Gas-rich Galaxy Pairs
Qifeng Huang, Jing Wang, Xuchen Lin +16
Galaxy interactions can significantly affect the star formation in galaxies, but it remains a challenge to achieve a consensus on the star formation rate (SFR) enhancement in galax…
FAST-ASKAP Synergy: Quantifying Coexistent Tidal and Ram Pressure Strippings in the NGC 4636 Group
Xuchen Lin, Jing Wang, Virginia Kilborn +27
Combining new HI data from a synergetic survey of ASKAP WALLABY and FAST with the ALFALFA data, we study the effect of ram pressure and tidal interactions in the NGC 4636 group. We…
The MeerKAT Absorption Line Survey (MALS)
N. Gupta, R. Srianand, W. Baan +41
Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
