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…

BIG-SPARC: The new SPARC database

Konstantin Haubner, Federico Lelli, Enrico Di Teodoro +5

The Surface Photometry and Accurate Rotation Curves (SPARC) database has provided the community with mass models for 175 nearby galaxies, allowing different research teams to test…
