Deep Narrowband Photometry of the M101 Group: Strong-Line Abundances of 720 HII Regions
Ray Garner, J. Christopher Mihos, Paul Harding +2
We present deep, narrowband imaging of the nearby spiral galaxy M101 and its satellites to analyze the oxygen abundances of their HII regions. Using CWRU's Burrell Schmidt telescop…
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…
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 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…
Galactic Mass-to-Light Ratios With Superfluid Dark Matter
Tobias Mistele, Stacy McGaugh, Sabine Hossenfelder
We make rotation curve fits to test the superfluid dark matter model. In addition to verifying that the resulting fits match the rotation curve data reasonably well, we aim to eval…
