Cepheid Distances to SNe Ia Host Galaxies based on a Revised Photometric Zero-Point of the HST-WFPC2 and New P-L Relations and Metallicity Corrections
A. Saha, F. Thim, G. A. Tammann +2
With this paper we continue the preparation for a forthcoming summary report of our experiment with the Hubble Space Telescope (HST) to determine the Hubble constant using type Ia…
Faint BVRI Photometric Sequences in Selected Fields
A. Saha, A. E. Dolphin, F. Thim +1
The results from work done to extend the Johnson-Cousins BVRI photometric standard sequence to faint levels of V ~ 21 mag in compact fields is presented. Such calibration and exten…
Cepheids and Long Period Variables in NGC 4395
F. Thim, J. G. Hoessel, A. Saha +3
Repeated imaging observations of NGC 4395 were made with the WIYN 3.5 m and the KPNO 2.1 m telescopes. From the photometry of the resolved brighter stars in this galaxy eleven Ceph…
Short-Period Variable Stars in the M31 Halo
A. E. Dolphin, A. Saha, E. W. Olszewski +4
We report the findings of a new search for RR Lyraes in an M31 halo field located 40 arcminutes from the nucleus of the galaxy along the minor axis. We detected 37 variable stars,…
The Cepheid Distance to NGC 5236 (M 83) with the VLT
Frank Thim, G. A. Tammann, A. Saha +4
Cepheids have been observed in NGC 5236 (M 83) using the ANTU (UT1) 8.2 meter telescope of the ESO VLT with FORS1. Observations over 34 epochs in V and I have been made between Jan…
Cepheids, Supernovae, Ho, and the Age of the Universe
G. A. Tammann, B. Reindl, F. Thim +2
The local expansion field is mapped using Cepheids, a complete sample of TF distances, and nearby cluster distances. The large-scale field is mapped using Cepheid-calibrated blue S…
