The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
Tracing the stellar component of low surface brightness Milky Way Dwarf Galaxies to their outskirts I: Sextans
L. Cicuendez, G. Battaglia, M. Irwin +12
We present results from deep and very spatially extended CTIO/DECam and photometry (reaching out to 2 mag below the oldest MSTO and covering 20 deg) aroun…
The PAndAS view of the Andromeda satellite system - II. Detailed properties of 23 M31 dwarf spheroidal galaxies
Nicolas F. Martin, Rodrigo A. Ibata, Geraint F. Lewis +15
We present a comprehensive analysis of the structural properties and luminosities of the 23 dwarf spheroidal galaxies that fall within the footprint of the Pan-Andromeda Archaeolog…
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…
Major Substructure in the M31 Outer Halo: Distances and Metallicities along the Giant Stellar Stream
Anthony R. Conn, Brendan McMonigal, Nicholas F. Bate +9
We present a renewed look at M31's Giant Stellar Stream along with the nearby structures Stream C and Stream D, exploiting a new algorithm capable of fitting to the red giant branc…
Major Substructure in the M31 Outer Halo: the East Cloud
B. McMonigal, N. F. Bate, A. R. Conn +8
We present the first detailed analysis of the East Cloud, a highly disrupted diffuse stellar substructure in the outer halo of M31. The core of the substructure lies at a projected…
The shell game: a panoramic view of Fornax
N. F. Bate, B. McMonigal, G. F. Lewis +4
We present a panoramic study of the Fornax dwarf spheroidal galaxy, using data obtained as part of the VLT Survey Telescope (VST) ATLAS Survey. The data presented here -- a subset…
Accretion in action: phase space coherence of stellar debris and globular clusters in Andromeda's South-West Cloud
Dougal Mackey, Geraint Lewis, Michelle Collins +13
A central tenet of the current cosmological paradigm is that galaxies grow over time through the accretion of smaller systems. Here, we present new kinematic measurements near the…
Sailing under the Magellanic Clouds: A DECam View of the Carina Dwarf
B. McMonigal, N. F. Bate, G. F. Lewis +7
We present deep optical photometry from the DECam imager on the 4m Blanco telescope of over 12 deg around the Carina dwarf spheroidal, with complete coverage out to 1 degree an…
Major Substructure in the M31 Outer Halo: the South-West Cloud
N. F. Bate, A. R. Conn, B. McMonigal +11
We undertake the first detailed analysis of the stellar population and spatial properties of a diffuse substructure in the outer halo of M31. The South-West Cloud lies at a project…
The Alcubierre Warp Drive: On the Matter of Matter
Brendan McMonigal, Geraint F. Lewis, Philip O'Byrne
The Alcubierre warp drive allows a spaceship to travel at an arbitrarily large global velocity by deforming the spacetime in a bubble around the spaceship. Little is known about th…
