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 ~…
Identification of the donor in GRS 1915+105
J. Greiner, M. J. McCaughrean, J. G. Cuby +2
We report on the results of medium-resolution spectroscopy of GRS 1915+105 in the H and K band using the 8m VLT at ESO. We clearly identify absorption bandheads from CO12 and CO13.…
The brightness of SN 1991T and the uniformity of decline-rate and colour corrected absolute magnitudes of supernovae Ia
T. Richtler, J. B. Jensen, J. Tonry +2
We present a distance to NGC 4527, the host galaxy of the type Ia SN 1991T, measured by surface brightness fluctuations. This supernova has been labelled ``peculiar'' both on the g…
Globular Clusters as Probes of the Virgo gE NGC 4472
Terry Bridges, Keith Ashman, Mike Beasley +4
We present radial velocities for 144 globular clusters around the Virgo gE NGC 4472 (M49), and ages and metallicities from co-added spectra of 131 clusters. We confirm our earlier…
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…
omega Centauri - a former nucleus of a dissolved dwarf galaxy? New evidence from Stroemgren photometry
Michael Hilker, Tom Richtler
CCD vby Stroemgren photometry of a statistically complete sample of red giants and stars in the main sequence turn-off region in omega Centauri has been used to analyse the apparen…
Ages and Metallicities of Globular Clusters in NGC 4472
M. A. Beasley, R. M. Sharples, T. J. Bridges +4
We have derived ages and metallicities from co-added spectra of 131 globular clusters associated with the giant elliptical galaxy NGC 4472. Based upon a calibration with Galactic g…
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…
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…
A Direct Distance to the LMC Cepheid HV 12198 from the Infrared Surface Brightness Technique
W. P. Gieren, J. Storm, P. Fouque +2
We report on a first application of the infrared surface brightness technique on a Cepheid in the Large Magellanic Cloud, the variable HV 12198 in the young globular cluster NGC 18…
Wide Field CCD Surface Photometry of the Giant Elliptical Galaxy NGC 4472 in the Virgo Cluster
Eunhyeuk Kim, Myung Gyoon Lee, Doug Geisler
We present deep wide field (16'.4 x 16'.4) Washington CT1 CCD surface photometry of the giant elliptical galaxy NGC 4472, the brightest member in the Virgo cluster. Our data cover…
