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…
One Stream or Two -- Exploring Andromeda's North West Stream
Janet Preston, Denis Erkal, Michelle L. M. Collins +3
We present results of our dynamical stream modelling for the North West Stream in the outer halo of the Andromeda galaxy (M31). Comprising two main segments, the North West Stream…
Properties of the Lower Segment of M31's North West Stream
Janet Preston, Denis Erkal, Michelle L. M. Collins +2
We present a kinematic and spectroscopic analysis of 40 red giant branch stars, in 9 fields, exquisitely delineating the lower segment of the North West Stream (NW-K2), which exten…
The Blanco DECam Bulge Survey. I. The Survey Description and Early Results
R. Michael Rich, Christian I. Johnson, Michael Young +18
The Blanco Dark Energy Camera (DECam) Bulge survey is a Vera Rubin Observatory (LSST) pathfinder imaging survey, spanning sq. deg. of the Southern Galactic bulge, $-2^\c…
The dynamics of Andromeda's dwarf galaxies and stellar streams
Michelle L. M. Collins, R. Michael Rich, Rodrigo A. Ibata +2
As part of the Z-PAndAS Keck II DEIMOS survey of resolved stars in our neighboring galaxy, Andromeda (M31), we have built up a unique data set of measured velocities and chemistrie…
PAndAS' cubs: discovery of two new dwarf galaxies in the surroundings of the Andromeda and Triangulum galaxies
Nicolas F. Martin, Alan W. McConnachie, Mike Irwin +10
We present the discovery of two new dwarf galaxies, Andromeda XXI and Andromeda XXII, located in the surroundings of the Andromeda and Triangulum galaxies (M31 and M33). These disc…
The remnants of galaxy formation from a panoramic survey of the region around M31
Alan W. McConnachie, Michael J. Irwin, Rodrigo A. Ibata +26
In hierarchical cosmological models, galaxies grow in mass through the continual accretion of smaller ones. The tidal disruption of these systems is expected to result in loosely b…
The Stellar Content of the Southern Tail of NGC 4038/9 and a Revised Distance
I. Saviane, J. Hibbard, R. M. Rich
We have used the Hubble Space Telescope and Wide Field Planetary Camera 2 to image the putative tidal dwarf galaxy located at the tip of the Southern tidal tail of NGC 4038/9, the…
