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…
Newly-Discovered Globular Clusters in NGC 147 and NGC 185 from PAndAS
J. Veljanoski, A. M. N. Ferguson, A. P. Huxor +8
Using data from the Pan-Andromeda Archaeological Survey (PAndAS), we have discovered four new globular clusters (GCs) associated with the M31 dwarf elliptical (dE) satellites NGC 1…
