The Stellar Content and Distance of UGC 4483
A. E. Dolphin, L. Makarova, I. D. Karachentsev +7
We present HST/WFPC2 observations of UGC 4483, an irregular galaxy in the M81/NGC 2403 complex. Stellar photometry was carried out with HSTphot, and is complete to V ~ 26.0 and I ~…
Dwarf Spheroidal Galaxies in the M81 Group Imaged with WFPC2
I. D. Karachentsev, V. E. Karachentseva, A. E. Dolphin +7
We obtained HST/WFPC2 images of the dwarf spheroidal (dSph) galaxies K61, K63, K64, DDO78, BK6N, and kk77 in the M81 group. Our color-magnitude diagrams show red giant branches wit…
Dynamical Constraints on the Formation of NGC 4472 and Its Globular Clusters
Stephen E. Zepf, Michael A. Beasley, Terry J. Bridges +4
We present new radial velocities for 87 globular clusters around the elliptical galaxy NGC 4472, and combine these with our previously published data to create a data set of veloci…
Hubble Space Telescope Photometry of the Dwarf Spheroidal Galaxy ESO 410-G005
Igor D. Karachentsev, Margarita E. Sharina, Eva K. Grebel +7
We present HST WFPC2 imaging of the nearby low-surface-brightness dwarf spheroidal galaxy ESO 410-G005, which has been resolved into stars for the first time. The resulting color-m…
A Dwarf Galaxy Survey in the Local Volume
E. K. Grebel, P. Seitzer, A. E. Dolphin +6
We are carrying out a comprehensive multi-wavelength study of dwarf galaxies in the Local Volume (< 5 Mpc). After our all-sky survey more than doubled the dwarf census we are now m…
Cepheid variables in the LMC cluster NGC 1866. I. New BVRI CCD photometry
W. P. Gieren, M. Gomez, J. Storm +5
We report BV(RI)c CCD photometric data for a group of seven Cepheid variables in the young, rich cluster NGC 1866 in the Large Magellanic Cloud. The photometry was obtained as part…
