Maximizing Science in the Era of LSST: A Community-Based Study of Needed US Capabilities
Joan Najita, Beth Willman, Douglas P. Finkbeiner +48
The Large Synoptic Survey Telescope (LSST) will be a discovery machine for the astronomy and physics communities, revealing astrophysical phenomena from the Solar System to the out…
An observer's guide to the (Local Group) dwarf galaxies: predictions for their own dwarf satellite populations
Gregory A. Dooley, Annika H. G. Peter, Tianyi Yang +3
A recent surge in the discovery of new ultrafaint dwarf satellites of the Milky Way has inspired the idea of searching for faint satellites, $10^3\, \mathrm{M_{\odot}} < M_* < 10^6…
First results from the MADCASH Survey: A Faint Dwarf Galaxy Companion to the Low Mass Spiral Galaxy NGC 2403 at 3.2 Mpc
Jeffrey L. Carlin, David J. Sand, Paul Price +13
We report the discovery of the faintest known dwarf galaxy satellite of an LMC stellar-mass host beyond the Local Group, based on deep imaging with Subaru/Hyper Suprime-Cam. MADCAS…
Dynamical evidence for a strong tidal interaction between the Milky Way and its satellite, Leo V
Michelle L. M. Collins, Erik J. Tollerud, David J. Sand +3
We present a chemodynamical analysis of the Leo~V dwarf galaxy, based on Keck II DEIMOS spectra of 8 member stars. We find a systemic velocity for the system of $\langle v_r\rangle…
Deep imaging of Eridanus II and its lone star cluster
D. Crnojević, D. J. Sand, D. Zaritsky +3
We present deep imaging of the most distant dwarf discovered by the Dark Energy Survey, Eridanus II (Eri II). Our Magellan/Megacam stellar photometry reaches mag deeper t…
