HI Galaxy Science with the SKA
Jing Wang, D. J. Pisano, Sarah Blyth +9
This chapter introduces the contributions of the HI galaxy science in this volume reviewing the latest developments and urgent questions in HI galaxy science, providing guiding pri…
Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21
The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…
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…
FEASTS and MHONGOOSE: HI Column Density Distribution at for
Jing Wang, Xuchen Lin, Ze-Zhong Liang +24
We present the first HI column density distribution function, , extending down to . This was derived from high-s…
Murriyang cryogenic phased array feed: spectral-line results and noise-reduction methods
L. Staveley-Smith, S. Barker, R. Berangi +25
Spectral-line results from a new cryogenic phased array feed (cryoPAF) on the Murriyang telescope at Parkes are presented. This array offers a significant improvement in field of v…
Flat tails in FRB and pulsar energy distributions: implications for optimizing nearby FRB surveys
S. B. Zhang, G. Hobbs, S. Johnston +6
Fast radio bursts (FRBs) are energetic, short-duration radio pulses of unclear origin. To explore effective survey strategies for detecting FRBs from nearby globular clusters (GCs)…
