It's Not Just Star Formation: A trend of low dark matter densities in the Andromeda dwarf galaxy system
Connor S. Pickett, Michelle L. M. Collins, Justin I. Read +8
Dynamical mass modeling of Andromeda (M31) dwarf spheroidal (dSph) galaxies has revealed a growing trend of lower central dark matter (DM) densities than predicted by pure DM struc…
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…
Chemical abundances in the nucleus of the Sagittarius dwarf spheroidal galaxy
A. Mucciarelli, M. Bellazzini, R. Ibata +3
We present Iron, Magnesium, Calcium, and Titanium abundances for 235 stars in the central region of the Sagittarius dwarf spheroidal galaxy (within 9.0 arcmin ~70 pc from the cente…
The elusive stellar halo of the Triangulum Galaxy
B. McMonigal, G. F. Lewis, B. J. Brewer +7
The stellar halos of large galaxies represent a vital probe of the processes of galaxy evolution. They are the remnants of the initial bouts of star formation during the collapse o…
Comparing the observable properties of dwarf galaxies on and off the Andromeda plane
Michelle L. M. Collins, Nicolas F. Martin, R. M. Rich +6
The thin, extended planes of satellite galaxies detected around both the Milky Way and Andromeda are not a natural prediction of the LCDM paradigm. Galaxies in these distinct plane…
Kinematics of Outer Halo Globular Clusters in M31
J. Veljanoski, A. M. N. Ferguson, A. D. Mackey +12
We present the first kinematic analysis of the far outer halo globular cluster (GC) population in the Local Group galaxy M31. Our sample contains 53 objects with projected radii of…
