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…
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…
Modeling the Mass Distribution and Gravitational Potential of Nearby Disk Galaxies: Implications for the ISM Dynamical Equilibrium
Vivek Vijayakumar, Jiayi Sun, Eve C. Ostriker +5
We characterize stellar, gas, and dark matter mass distributions for 17 nearby massive disk galaxies from the PHANGS sample. This allows us to compute the gravitational potential t…
A New Uncertainty Scheme for Galaxy Distances from Flow Models
Konstantin Haubner, Federico Lelli, Enrico Di Teodoro +3
The systemic velocity or redshift of galaxies is a convenient tool to calculate their distances in the absence of primary methods, but the uncertainties on these flow distances may…
