Cored galaxies in cuspy dark matter halos
Fernando Valenciano, Jorge Martin Camalich, Arianna Di Cintio +4
We investigate constraints on the inner stellar density profile from photometric data of dwarf spheroidal and ultra-faint dwarf galaxies. Our aim is to clarify under what condition…
GravSphere2: A higher-order Jeans method for mass-modeling spherical stellar systems
Andrés Bañares-Hernández, Justin I. Read, Mariana P. Júlio
Mass-modeling methods are used to infer the gravitational field of stellar systems, from globular clusters to giant elliptical galaxies. While many methods exist, most require assu…
Mass Modeling the Andromeda Dwarf Galaxies: Andromeda VI and Andromeda XXIII
Connor S. Pickett, Michelle L. M. Collins, R. Michael Rich +7
Accurately mapping the mass profiles of low mass dwarf spheroidal (dSph) galaxies allows us to test predictions made by dark matter (DM) models. To date, such analyses have primari…
New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
Andrés Bañares-Hernández, Francesca Calore, Jorge Martin Camalich +1
We perform a combined analysis of stellar kinematics and line-of-sight accelerations of millisecond pulsars to investigate the mass contents of Omega Centauri. We consider multiple…
Discovery of Globular Cluster Candidates in the Dwarf Irregular Galaxy IC 2574 Using HST/ACS Imaging
Noushin Karim, Michelle L. M. Collins, Duncan A. Forbes +1
We report the discovery of 23 globular cluster (GC) candidates around the relatively isolated dwarf galaxy IC 2574 within the Messier 81 (M81) group, at a distance of 3.86 Mpc. We…
Fluctuations in galactic bar parameters due to bar-spiral interaction
T. Hilmi, I. Minchev, T. Buck +10
We study the late-time evolution of the central regions of two Milky Way-like simulations of galaxies formed in a cosmological context, one hosting a fast bar and the other a slow…
