The Carnegie Chicago Hubble Program VI: Tip of the Red Giant Branch Distances to M66 and M96 of the Leo I Group
Taylor J. Hoyt, Wendy L. Freedman, Barry F. Madore +8
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 targe…
Galaxy Structure in the Ultraviolet: The Dependence of Morphological Parameters on Rest-Frame Wavelength
Violet A. Mager, Christopher J. Conselice, Mark Seibert +5
Evolutionary studies that compare galaxy structure as a function of redshift are complicated by the fact that any particular galaxy's appearance depends in part on the rest-frame w…
The Metallicity Dependence of the Cepheid P-L Relation in M101
Violet A. Mager, Barry F. Madore, Wendy L. Freedman
The impact of metallicity on the Cepheid Period-Luminosity (P-L) relation is investigated using HST ACS V and I images of M101. Variations in the reddening-free Wesenheit parameter…
The Young Stellar Population of the Nearby Late-Type Galaxy NGC 1311
Paul B. Eskridge, Rogier A. Windhorst, Violet A. Mager +1
We have extracted PSF-fitted stellar photometry from near-ultraviolet, optical and near-infrared images, obtained with the Hubble Space Telescope, of the nearby (D ~ 5.5 Mpc) SBm g…
The Cepheid Period-Luminosity Relation (The Leavitt Law) at Mid-Infrared Wavelengths: IV. Cepheids in IC 1613
Wendy L. Freedman, Jane Rigby, Barry F. Madore +3
We present mid-infrared Period-Luminosity relations for Cepheids in the Local Group galaxy IC1613. Using archival IRAC imaging data from Spitzer we were able to measure single-epoc…
The Cepheid Period-Luminosity Relation (The Leavitt Law) at Mid-Infrared Wavelengths: III. Cepheids in NGC 6822
Barry F. Madore, Jane Rigby, Wendy L. Freedman +3
We present the first application of mid-infrared Period-Luminosity relations to the determination of a Cepheid distance beyond the Magellanic Clouds. Using archival IRAC imaging da…
