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…

The baryonic mass-size relation of galaxies. II. Implications for the evolutionary paths between star-forming and passive galaxies

Zichen Hua, Lelli Federico, Enrico Di Teodoro +2

The baryonic mass-size relation of galaxies links the total baryonic mass (stars plus gas) to the baryonic half-mass radius. In the first paper of this series, we showed that star-…

The baryonic mass-size relation of galaxies. I. A dichotomy in star-forming galaxy disks

Zichen Hua, Federico Lelli, Enrico Di Teodoro +2

The mass-size relations of galaxies are generally studied considering only stars or only gas separately. Here we study the baryonic mass-size relation of galaxies from the SPARC da…

Mass models of galaxy clusters from a non-parametric weak-lensing reconstruction

Tobias Mistele, Federico Lelli, Stacy McGaugh +2

We study the CLASH sample of galaxy clusters using a new deprojection method for weak gravitational lensing observations. This method is non-parametric, allowing us to infer mass p…

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…

The Baryonic Tully-Fisher Relation II: Stellar Mass Models

Francis Duey, James Schombert, Stacy McGaugh +1

We present new color- (mass-to-light) models to convert WISE W1 fluxes into stellar masses. We outline a range of possible star formation histories and chemical evolution sce…
