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…
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…
