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…
The Baryonic Faber-Jackson Relation and Fundamental Plane of Galaxy Groups, Elliptical Galaxies, and Dwarf Galaxies
Yong Tian, Federico Lelli, Marcel S. Pawlowski +7
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to…
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…
WISDOM Project -- XXVIII. Molecular gas measurement of the supermassive black hole mass of the galaxy NGC 1387
Pandora Dominiak, Martin Bureau, Fu-Heng Liang +6
Supermassive black hole (SMBH) masses can be measured using molecular gas kinematics. Here we present high angular resolution ( arcsec or pc) Atacama Large Millim…
The Baryonic Mass-Halo Mass Relation of Extragalactic Systems
Stacy McGaugh, Tobias Mistele, Francis Duey +4
We combine data for extragalactic systems to quantify a relation between the observed baryonic mass and the enclosed dynamical mass inferred from kinematics or grav…
WISDOM project -- XVIII. Molecular gas distributions and kinematics of three megamaser galaxies
Fu-Heng Liang, Mark D. Smith, Martin Bureau +11
The co-evolution of galaxies and supermassive black holes (SMBHs) underpins our understanding of galaxy evolution, but different methods to measure SMBH masses have only infrequent…
