The galactic HI-to-halo mass relation from isolated galaxies to cosmological hydrodynamic simulations
Marie Korsaga, Jonathan Freundlich, Benoit Famaey +15
The relation between HI and dark matter (DM) halo masses provides key insights into gas accretion and the regulation of galaxy formation. In a previous study based on SPARC and LIT…
The molecular gas of four ram pressure stripped galaxies in the core of the Hydra I cluster
Clara C. de la Casa, Kelley M. Hess, Nikki Zabel +15
We present new CO(1-0) measurements from ALMA and new HI measurements from MeerKAT in four ram pressure stripped (RPS) galaxies in the core of the Hydra I cluster: NGC 3312, NGC 33…
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…
From Atomic Gas to Star Formation
Erik Rosolowsky, Eric Koch, Sambit Roychowdhury +9
Since the 2015 SKA Chapters, the advent of panchromatic observations of nearby galaxies, capable of resolving the interstellar medium (ISM) into individual star-forming regions and…
Resolved HI and Environmental Dynamics
M. Ramatsoku, P. Serra, N. Deg +8
Spatially resolved, deep HI observations from SKA precursors and pathfinders such as MeerKAT, FAST, and ASKAP have demonstrated their ability to reveal the complex interactions bet…
Classification of HI Galaxy Profiles Using Unsupervised Learning and Convolutional Neural Networks: A Comparative Analysis and Methodological Cases of Studies
Gabriel Jaimes-Illanes, Manuel Parra-Royon, Laura Darriba-Pol +5
Hydrogen, the most abundant element in the universe, is crucial for understanding galaxy formation and evolution. The 21 cm neutral atomic hydrogen - HI spectral line maps the gas…
