LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
At the heart of the matter: the origin of bulgeless dwarf galaxies and Dark Matter cores
Fabio Governato, Chris Brook, Lucio Mayer +8
For almost two decades the properties of "dwarf" galaxies have challenged the Cold Dark Matter (CDM) paradigm of galaxy formation. Most observed dwarf galaxies consists of a rotati…
A Deeper Look at Leo IV: Star Formation History and Extended Structure
D. J. Sand, A. Seth, E. W. Olszewski +3
We present MMT/Megacam imaging of the Leo~IV dwarf galaxy in order to investigate its structure and star formation history, and to search for signs of association with the recently…
Turning the Tides on the Ultra-Faint Dwarf Spheroidal Galaxies: Coma Berenices and Ursa Major II
Ricardo R. Munoz, Marla Geha, Beth Willman
We present deep CFHT/MegaCam photometry of the ultra-faint Milky Way satellite galaxies Coma Berenices (ComBer) and Ursa Major II (UMa II). These data extend to r~25, corresponding…
In Pursuit of the Least Luminous Galaxies
Beth Willman
The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10^-7 L_MW, they inhabit the lowest mass dark matter halos known to h…
The Star Formation History and Extended Structure of the Hercules Milky Way Satellite
D. J. Sand, E. W. Olszewski, B. Willman +5
We present imaging of the recently discovered Hercules Milky Way satellite and its surrounding regions to study its structure, star formation history and to thoroughly search for s…
