The Bright Future of the Dark and Dim Universe
N. Deg, Alejandro Benitez-Llambay, Elizabeth A. K. Adams +5
This chapter investigates the low-mass frontier of galaxy formation through two complementary populations: the starless Reionization-Limited HI Clouds (RELHICs) that trace the ``da…
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: A gas-rich diffuse dwarf on the baryonic Tully Fisher relation
Rebecca Dudley, N. Deg, Kristine Spekkens +5
Diffuse dwarf galaxies, and particularly ultra diffuse galaxies (UDGs), challenge our understanding of galaxy formation and the role of dark matter due to their large sizes, low su…
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…
The central spectra of massive star-forming galaxies
Jaimie R. Sheil, Michael J. I . Brown, Virginia A. Kilborn +2
We have examined the nuclear spectra of very massive star-forming galaxies at to understand how they differ from other galaxies with comparable masses, which are typical…
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…
