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…
Sharpening the Tip of the Red Giant Branch
Barry F. Madore, Violet Mager, Wendy L. Freedman
We introduce a modified detection method for measuring the luminosity of the tip of the red giant branch (TRGB) by introducing the composite magnitude T = I - beta [(V-I)_o - 1.50]…
Metallicity-corrected Tip of the Red Giant Branch Distance to NGC 4258
Violet A. Mager, Barry F. Madore, Wendy L. Freedman
We have determined the distance to NGC 4258 using observations made with the Hubble Space Telescope (HST) and the Wide Field, Advanced Camera for Surveys (ACS/WFC). We apply a modi…
A New Distance to The Antennae Galaxies (NGC 4038/39) Based on the Type Ia Supernova 2007sr
Francois Schweizer, Christopher R. Burns, Barry F. Madore +13
Traditionally, the distance to NGC 4038/39 has been derived from the systemic recession velocity, yielding about 20 Mpc for H_0 = 72 km/s/Mpc. Recently, this widely adopted distanc…
