Exploring the Very Extended Low Surface Brightness Stellar Populations of the Large Magellanic Cloud with SMASH
David L. Nidever, Knut Olsen, Yumi Choi +23
We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R~21 degrees, or ~18.5 kpc at the LMC distance of 50 kpc, as detected i…
SMASH - Survey of the MAgellanic Stellar History
David L. Nidever, Knut Olsen, Alistair R. Walker +36
The Large and Small Magellanic Clouds (LMC and SMC) are unique local laboratories for studying the formation and evolution of small galaxies in exquisite detail. The Survey of the…
SMASH 1: a very faint globular cluster disrupting in the outer reaches of the LMC?
Nicolas F. Martin, Valentin Jungbluth, David L. Nidever +20
We present the discovery of a very faint stellar system, SMASH 1, that is potentially a satellite of the Large Magellanic Cloud. Found within the Survey of the MAgellanic Stellar H…
Variable stars in the field of the Hydra II ultra-faint dwarf galaxy
A. Katherina Vivas, Knut Olsen, Robert Blum +12
We report the discovery of one RR Lyrae star in the ultra--faint satellite galaxy Hydra II based on time series photometry in the g, r and i bands obtained with the Dark Energy Cam…
Hydra II: a faint and compact Milky Way dwarf galaxy found in the Survey of the Magellanic Stellar History
Nicolas F. Martin, David L. Nidever, Gurtina Besla +26
We present the discovery of a new dwarf galaxy, Hydra II, found serendipitously within the data from the ongoing Survey of the MAgellanic Stellar History (SMASH) conducted with the…
The Resolved Stellar Population in 50 Regions of M83 from HST/WFC3 Early Release Science Observations
Hwihyun Kim, Bradley C. Whitmore, Rupali Chandar +22
We present a multi-wavelength photometric study of ~15,000 resolved stars in the nearby spiral galaxy M83 (NGC5236, D=4.61Mpc) based on Hubble Space Telescope Wide Field Camera 3 o…
