New dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy
Ethan Crosby, Helmut Jerjen, Oliver Müller +3
We report the discovery of 40 new satellite dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy (M104) the most luminous galaxy in the Local Volume. Using the…
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…
Radial acceleration relation of galaxies with joint kinematic and weak-lensing data
Tobias Mistele, Stacy McGaugh, Federico Lelli +2
We combine kinematic and gravitational lensing data to construct the Radial Acceleration Relation (RAR) of galaxies over a large dynamic range. We improve on previous weak-lensing…
Molecular and Ionized Gas in Tidal Dwarf Galaxies: The Spatially Resolved Star-Formation Relation
Navyasree Kovakkuni, Federico Lelli, Pierre-alain Duc +12
Tidal dwarf galaxies (TDGs) are low-mass objects that form within tidal and/or collisional debris ejected from more massive interacting galaxies. We use CO() observations from…
A fundamental plane of black hole accretion at millimetre wavelengths
Ilaria Ruffa, Timothy A. Davis, Jacob S. Elford +11
We report the discovery of the ``mm fundamental plane of black-hole accretion'', which is a tight correlation between the nuclear 1 mm luminosity (), the intrinsic $…
Mass models of disk galaxies from gas dynamics
Federico Lelli
I review methods and techniques to build mass models of disk galaxies from gas dynamics. I focus on two key steps: (1) the derivation of rotation curves using 3D emission-line data…
Gas, dust, and the CO-to-molecular gas conversion factor in low-metallicity starbursts
L. K. Hunt, F. Belfiore, F. Lelli +19
The factor relating CO emission to molecular hydrogen column density, XCO, is still subject to uncertainty, in particular at low metallicity. Here, to quantify XCO at two different…
WISDOM project -- XIV. SMBH mass in the early-type galaxies NGC0612, NGC1574, and NGC4261 from CO dynamical modelling
Ilaria Ruffa, Timothy A. Davis, Michele Cappellari +9
We present a CO dynamical estimate of the mass of the super-massive black hole (SMBH) in three nearby early-type galaxies: NGC0612, NGC1574 and NGC4261. Our analysis is based on At…
Measuring galaxy cluster mass profiles into the low acceleration regime with galaxy kinematics
Pengfei Li, Yong Tian, Mariana P. Júlio +7
We probe the dynamical mass profiles of 10 galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solve the spherical…
Cold gas disks in main-sequence galaxies at cosmic noon: Low turbulence, flat rotation curves, and disk-halo degeneracy
Federico Lelli, Zhi-Yu Zhang, Thomas G. Bisbas +6
We study the dynamics of cold molecular gas in two main-sequence galaxies at cosmic noon (zC-488879 at and zC-400569 at ) using new high-resolution ALMA…
Dynamical signature of a stellar bulge in a quasar host galaxy at
Roberta Tripodi, Federico Lelli, Chiara Feruglio +4
We present a dynamical analysis of a quasar-host galaxy at (SDSS J2310+1855) using a high-resolution ALMA observation of the [CII] emission line. The observed rotation…
