WALLABY Pilot Survey: Public release of HI kinematic models for more than 100 galaxies from phase 1 of ASKAP pilot observations
N. Deg, K. Spekkens, T. Westmeier +29
We present the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) Pilot Phase I HI kinematic models. This first data release consists of HI observations of three fields i…
Testing Modified Gravity Theories with Numerical Solutions of the External Field Effect in Rotationally Supported Galaxies
Kyu-Hyun Chae, Federico Lelli, Harry Desmond +2
The strong equivalence principle is violated by gravity theories of Milgromian dynamics (MOND) through the action of the external field effect. We test two different Lagrangian the…
Shaken, not blown: the gentle baryonic feedback of nearby starburst dwarf galaxies
A. Marasco, F. Belfiore, G. Cresci +12
Baryonic feedback is expected to play a key role in regulating the star formation of low-mass galaxies by producing galaxy-scale winds associated with mass-loading factors $β\!\sim…
WISDOM Project -- XIII. Feeding molecular gas to the supermassive black hole in the starburst AGN-host galaxy Fairall 49
Federico Lelli, Timothy A. Davis, Martin Bureau +5
The mm-Wave Interferometric Survey of Dark Object Masses (WISDOM) is probing supermassive black holes (SMBHs) in galaxies across the Hubble sequence via molecular gas dynamics. We…
Incorporating baryon-driven contraction of dark matter halos in rotation curve fits
Pengfei Li, Stacy S. McGaugh, Federico Lelli +2
The condensation of baryons within a dark matter (DM) halo during galaxy formation should result in some contraction of the halo as the combined system settles into equilibrium. We…
The Present and Future of Astronomy (ASTRO2022)
Giacomo Beccari, Henri M. J. Boffin, Paola Andreani +7
Being one of the most fascinating and ancient sciences, astronomy has always played a special role in society. In 2022 ESO organised an online conference to offer the community a p…
WISDOM Project -- X. The morphology of the molecular ISM in galaxy centres and its dependence on galaxy structure
Timothy A. Davis, Jindra Gensior, Martin Bureau +12
We use high-resolution maps of the molecular interstellar medium (ISM) in the centres of eighty-six nearby galaxies from the millimetre-Wave Interferometric Survey of Dark Object M…
The Effect of Adiabatic Compression on Dark Matter Halos and the Radial Acceleration Relation
Pengfei Li, Stacy S. McGaugh, Federico Lelli +3
We use a semi-empirical model to investigate the radial acceleration relation (RAR) in a cold dark matter (CDM) framework. Specifically, we build 80 model galaxies covering the sam…
Stellar Mass-to-light Ratios: Composite Bulge+Disk Models and the Baryonic Tully-Fisher Relation
James Schombert, Stacy McGaugh, Federico Lelli
We present stellar population models to calculate the mass-to-light ratio () based on galaxy's colors ranging from FUV to Spitzer IRAC1 at 3.6m. We present a new co…
Gas dynamics in dwarf galaxies as testbeds for dark matter and galaxy evolution
Federico Lelli
Dwarf galaxies are ideal laboratories to test dark matter models and alternative theories because their dynamical mass (from observed kinematics) largely outweighs their baryonic m…
