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 ~…
The Hamburg/SAO Survey for Emission--Line Galaxies. IV. The Fourth List of 119 Galaxies
A. Y. Kniazev, D. Engels, S. A. Pustilnik +11
We present the fourth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS hereafter, SAO - Special Astrophysical Observatory, Russia). The list is a result…
Gas motions in the plane of the spiral galaxy NGC 3631
A. M. Fridman, O. V. Khoruzhii, E. V. Polyachenko +7
The velocity field of the nearly face-on galaxy NGC 3631, derived from observations in the H alpha line and the HI radio line, is analysed to study perturbations related to the spi…
A Giant Bipolar Shell around the WO star in the Galaxy IC 1613: Structure and Kinematics
V. L. Afanasiev, T. A. Lozinskaya, A. V. Moiseev +1
Observations of the nebula associated with the WO star in the galaxy IC 1613 are presented. The observations were carried out with a scanning Interferometer Fabry-Perot in H_alpha…
Observation of X-ray lines from a Gamma-Ray Burst (GRB991216): Evidence of Moving Ejecta from the Progenitor
L. Piro, G. Garmire, M. Garcia +18
We report on the discovery of two emission features observed in the X-ray spectrum of the afterglow of the gamma-ray burst (GRB) of 16 Dec. 1999 by the Chandra X-Ray Observatory. T…
VLA HI Line Observations of the Extremely Metal-Poor Blue Compact Dwarf Galaxy SBS 0335-052
S. A. Pustilnik, E. Brinks, T. X. Thuan +2
We present the results of HI mapping with the NRAO VLA of one of the most metal-deficient blue compact dwarf (BCD) galaxies known, SBS 0335-052, with an oxygen abundance of only 1/…
