The Distribution of Atomic Hydrogen in the Host Galaxies of FRBs
Hugh Roxburgh, Marcin Glowacki, Clancy W. James +14
We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quad…
Baryonic Masses and Properties of Gaseous Satellite Galaxies
Jingyao Zhu, Yasmeen Asali, Mary Putman +12
We present a sample of 127 gas-bearing dwarf galaxies around 56 late-type host galaxies within 30 Mpc using 21-cm HI data from the WALLABY, MHONGOOSE, and ALFALFA surveys. We chara…
WALLABY: an untargeted search for H I-bearing ultra-diffuse galaxies uncovers the first known ultra-diffuse galaxy pair
T. O'Beirne, V. A. Kilborn, M. E. Cluver +14
Using the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) we performed an untargeted search for H I-bearing ultra-diffuse galaxies (UDGs). We identified a core sample…
WALLABY Pilot Survey: Characterizing Low Rotation Kinematically Modelled Galaxies
N. Deg, K. Spekkens, N. Arora +20
Many of the tensions in cosmological models of the Universe lie in the low mass, low velocity regime. Probing this regime requires a statistically significant sample of galaxies wi…
WALLABY Pilot Survey: the extensive interaction of NGC 4532 and DDO 137 with the Virgo cluster
L. Staveley-Smith, K. Bekki, A. Boselli +16
As part of the pilot survey of the Widefield ASKAP L-band Legacy All-sky Survey (WALLABY), high-resolution neutral atomic hydrogen (HI) observations of the dwarf galaxy pair NGC 45…
The First Large Absorption Survey in HI (FLASH): II. Pilot Survey data release and first results
Hyein Yoon, Elaine M. Sadler, Elizabeth K. Mahony +41
The First Large Absorption Survey in HI (FLASH) is a large-area radio survey for neutral hydrogen in the redshift range 0.4<z<1.0, using the 21cm HI absorption line as a probe of c…
