Distances to Local Group Galaxies via Population II, Stellar Distance Indicators I: The Sculptor Dwarf Spheroidal

Autor: Quang H. Tran, Taylor J. Hoyt, Wendy L. Freedman, Barry F. Madore, Elias K. Oakes, William Cerny, Dylan Hatt, Rachael L. Beaton

We determine the distance to the Sculptor Dwarf Spheroidal via three Population II stellar distance indicators: (a) the Tip of the Red Giant Branch (TRGB), (b) RR Lyrae variables (RRLs), and (c) the ridgeline of the blue horizontal branch (HB). High

The Carnegie Chicago Hubble Program VI: Tip of the Red Giant Branch Distances to M66 and M96 of the Leo I Group

Autor: Violet A. Mager, Rachael L. Beaton, Barry F. Madore, Taylor J. Hoyt, Andrew J. Monson, Jeffrey A. Rich, In Sung Jang, Jillian R. Neeley, Dylan Hatt, Myung Gyoon Lee, Wendy L. Freedman

We determine the distances to the Type Ia Supernova host galaxies M66 (NGC 3627) and M96 (NGC 3368) of the Leo I Group using the Tip of the Red Giant Branch (TRGB) method. We target the stellar halos of these galaxies using the Hubble Space Telescope

Many studies have shown that RR Lyrae variable stars (RRL) are powerful stellar tracers of Galactic halo structure and satellite galaxies. The Dark Energy Survey (DES), with its deep and wide coverage (g ~ 23.5 mag) in a single exposure; over 5000 de

The Near-Infrared Tip of the Red Giant Branch. II. An Absolute Calibration in the Large Magellanic Cloud

Autor: Andrew J. Monson, Dylan Hatt, Rachael L. Beaton, Myung Gyoon Lee, Barry F. Madore, Mark Seibert, Taylor J. Hoyt, In Sung Jang, Wendy L. Freedman, Jeffrey A. Rich

We present a new empirical \(JHK\) absolute calibration of the tip of the red giant branch (TRGB) in the Large Magellanic Cloud (LMC). We use published data from the extensive \emph{Near-Infrared Synoptic Survey} containing 3.5 million stars, of whic

We present photometry of 30 Galactic RR Lyrae variables taken with HST WFC3/IR for the Carnegie-Chicago Hubble Program. These measurements form the base of the distance ladder measurements that comprise a pure Population II base to a measurement of H
