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…
WISDOM Project -- XXV. Improving the CO-dynamical supermassive black hole mass measurement in the galaxy NGC 1574 using high spatial resolution ALMA observations
Hengyue Zhang, Martin Bureau, Ilaria Ruffa +5
We present a molecular gas dynamical supermassive black hole (SMBH) mass measurement in the nearby barred lenticular galaxy NGC 1574, using Atacama Large Millimeter/sub-millimeter…
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…
MUSE observations of dwarf galaxies and a stellar stream in the M83 group
Oliver Müller, Marina Rejkuba, Katja Fahrion +8
Spectroscopy for faint dwarf galaxies outside of our own Local Group is challenging. Here, we present MUSE spectroscopy to study the properties of four known dwarf satellites and o…
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 scen…
WISDOM Project -- XXII. A 5% precision CO-dynamical supermassive black hole mass measurement in the galaxy NGC 383
Hengyue Zhang, Martin Bureau, Ilaria Ruffa +8
We present a measurement of the supermassive black hole (SMBH) mass of the nearby lenticular galaxy NGC 383, based on Atacama Large Millimeter/sub-millimeter Array (ALMA) observati…
