WFPC2 CTE Characterization
Andrew E. Dolphin
The limiting factor of the accuracy of WFPC2 photometry is the CTE loss, which has increased to the level of 50% or more for faint stars at the top of the chips. I describe recent…
Deep HST Imaging of Sextans A. II. Cepheids and Distance
Andrew E. Dolphin, A. Saha, Evan D. Skillman +6
We have identified 82 short-period variable stars in Sextans A from deep WFPC2 observations. All of the periodic variables appear to be short-period Cepheids, with periods as small…
Local galaxy flows within 5 Mpc
I. D. Karachentsev, D. I. Makarov, M. E. Sharina +8
We present Hubble Space Telescope/WFPC2 images of sixteen dwarf galaxies as part of our snapshot survey of nearby galaxy candidates. We derive their distances from the luminosity o…
Galaxy Flow in the Canes Venatici I Cloud
I. D. Karachentsev, M. E. Sharina, A. E. Dolphin +7
We present an analysis of Hubble Space Telescope/WFPC2 images of eighteen galaxies in the Canes Venatici I cloud. We derive their distances from the luminosity of the tip of the re…
Tidal dwarfs in the M81 group: the second generation?
L. N. Makarova, E. K. Grebel, I. D. Karachentsev +8
We derive quantitative star formation histories of the four suspected tidal dwarf galaxies in the M81 group, HolmbergIX, BK3N, Arp-loop (A0952+69), and Garland, using Hubble Space…
