The oblateness of dark matter halos of nearby galaxies and its correlation with gas mass fractions
Mousumi Das, Roger Ianjamasimanana, Stacy McGaugh +2
We present a method to measure the the oblateness parameter q of the dark matter halos of gas rich galaxies that have extended HI disks. We have applied our model to a sample of 20…
Estimating the Oblateness Of Dark Matter Halos Using Neutral Hydrogen Velocity Dispersion
Mousumi Das, Roger Ianjamasimanana, Stacy S. McGaugh +2
We derive the oblateness parameter q of the dark matter halo of a sample of gas rich, face-on disk galaxies. We have assumed that the halos are triaxial in shape but their axes in…
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…
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…
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…
