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^…
Hidden in the Halo: New Diffuse Star Clusters in the M82 Starburst with JWST
Deepthi S. Prabhu, David J. Sand, Burcin Mutlu-Pakdil +12
Diffuse star clusters (DSCs) occupy a poorly explored region of the size-luminosity plane between classical globular clusters (GCs) and dwarf galaxies. Here we report the discovery…
Discovery, Characterization, and Potential Origins of a Stream in the Stellar Halo of Nearby LMC-Mass Galaxy NGC 55
Benjamin N. Velguth, Burçin Mutlu-Pakdil, Erik Tollerud +33
We present a previously undetected stellar stream in the halo of the LMC-mass dwarf galaxy NGC 55 (2 Mpc), as part of an ongoing effort to characterize the stellar halos of LMC/SMC…
Testing dark matter models and modified gravity theories with spatially resolved HI observations
Federico Lelli, Antonino Marasco, Timothy A. Davis +8
Understanding the nature of dark matter (DM) is one of the most pressing questions of modern physics. The flat rotation curves of galaxies, especially the extended HI rotation curv…
MIGHTEE-HI: Environmental effects of cosmic filaments on extragalactic HI detections in the COSMOS and XMM-LSS fields
Seoyoung Lyla Jung, Madalina N. Tudorache, Matt J. Jarvis +8
Cosmic filaments have been recognised as influencing galaxy evolution, but their connection to galactic cold gas reservoirs is elusive, particularly at low redshifts. We investigat…
MIGHTEE-HI / LADUMA: Investigating the link between baryons and dynamics with 130 resolved HI-selected galaxies
Andreea A Vărăşteanu, Matt J. Jarvis, Harry Desmond +15
The baryonic Tully-Fisher relation (bTFR) and the radial acceleration relation (RAR) link the observed dynamics in galaxies to that expected from their baryonic mass distributions.…
