No need for dark matter: resolved kinematics of the ultra-diffuse galaxy AGC 114905

Pavel E. Mancera Piña, Filippo Fraternali, Tom Oosterloo +3

We present new HI interferometric observations of the gas-rich ultra-diffuse galaxy AGC 114905, which previous work, based on low-resolution data, identified as an outlier of the b…

The effects of self-interacting dark matter on the stripping of galaxies that fall into clusters

Ellen L. Sirks, Kyle A. Oman, Andrew Robertson +2

We use the Cluster-EAGLE (C-EAGLE) hydrodynamical simulations to investigate the effects of self-interacting dark matter (SIDM) on galaxies as they fall into clusters. We find that…

The ALFALFA HI velocity width function

Kyle A. Oman

We make the most precise determination to date of the number density of extragalactic 21-cm radio sources as a function of their spectral line widths - the HI velocity width functi…

The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS-1000

Margot M. Brouwer, Kyle A. Oman, Edwin A. Valentijn +22

We present measurements of the radial gravitational acceleration around isolated galaxies, comparing the expected gravitational acceleration given the baryonic matter with the obse…

Satellites Around Milky Way Analogs: Tension in the Number and Fraction of Quiescent Satellites Seen in Observations Versus Simulations

Ananthan Karunakaran, Kristine Spekkens, Kyle A. Oman +13

We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage~II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those fro…

Velocity-dependent J-factors for annihilation radiation from cosmological simulations

Erin Board, Nassim Bozorgnia, Louis E. Strigari +6

We determine the dark matter pair-wise relative velocity distribution in a set of Milky Way-like halos in the Auriga and APOSTLE simulations. Focusing on the smooth halo component,…
