WALLABY pilot survey: accurate and automated linewidth measurements from global HI profiles

Shinna Kim, Tobias Westmeier, Lister Staveley-Smith +11

Current-generation 21-cm surveys of extragalactic neutral hydrogen (HI) with instruments such as FAST and ASKAP are providing detailed spectral and spatial information for over 10^…

MUSE-ALMA Haloes XVI: a census of the condensed baryons in z~0.5 HI absorption-selected galaxies

T. O'Beirne, C. Péroux, M. Zwaan +16

We use the MUSE-ALMA Haloes sample to build a census of the condensed baryons (stars and cold gas) to study the multiphase interstellar medium and circumgalactic medium (CGM). The…

WALLABY pilot survey: HI depletion times within the stellar discs of nearby galaxies

Seona Lee, Barbara Catinella, Tobias Westmeier +12

Neutral atomic hydrogen (HI) reservoirs typically extend far beyond the inner star-forming regions of galaxies, and global HI measurements, which mix these distinct environments, l…

WALLABY pilot survey: Blinded by the light -- discovery of a fourth member in the ESO 179-013 system

Rayssa Guimarães Silva, Marco Grossi, Denise R. Gonçalves +12

We present new ASKAP/WALLABY HI observations of the nearby dwarf galaxy system ESO 179-013 (Kathryn's Wheel), the nearest known collisional ring galaxy, located 10 Mpc away in the…

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…

WALLABY pilot survey: properties of HI-selected dark sources and low surface brightness galaxies

T. O'Beirne, L. Staveley-Smith, V. A. Kilborn +13

We examine the optical counterparts of the 1829 neutral hydrogen (HI) detections in three pilot fields in the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) using dat…

Low-Frequency Turnover Star Forming Galaxies I: Radio Continuum Observations and Global Properties

J. A. Grundy, N. Seymour, O. I. Wong +3

The broad-band radio spectral energy distribution (SED) of star-forming galaxies (SFGs) contains a wealth of complex physics. We aim to determine the physical emission and loss pro…

WALLABY Pilot Survey: Gas-Rich Galaxy Scaling Relations from Marginally-Resolved Kinematic Models

N. Deg, N. Arora, K. Spekkens +21

We present the first set of galaxy scaling relations derived from kinematic models of the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot phase observations. Com…

WALLABY Pilot Survey: Public data release of ~1800 HI sources and high-resolution cut-outs from Pilot Survey Phase 2

C. Murugeshan, N. Deg, T. Westmeier +20

We present the Pilot Survey Phase 2 data release for the Wide-field ASKAP L-band Legacy All-sky Blind surveY (WALLABY), carried-out using the Australian SKA Pathfinder (ASKAP). We…

The HI in Ring Galaxies Survey (HI-RINGS) -- Effects of the bar on the HI gas in ring galaxies

Chandrashekar Murugeshan, Robert Dzudzar, Ryan Bagge +6

We present a new high-resolution neutral atomic hydrogen (HI) survey of ring galaxies using the Australia Telescope Compact Array (ATCA). We target a sample of 24 ring galaxies fro…
