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…
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/…
An imaging and spectroscopic study of the very metal-deficient blue compact dwarf galaxy Tol 1214--277
K. J. Fricke, Y. I. Izotov, P. Papaderos +2
We present a spectrophotometric study based on VLT/FORS I observations of one of the most metal-deficient blue compact dwarf (BCD) galaxies known, Tol 1214-277 (Z ~ Zsun/25). The d…
The KPNO International Spectroscopic Survey. II. H-alpha Selected Survey List 1
J. J. Salzer, C. Gronwall, V. A. Lipovetsky +7
The KPNO International Spectroscopic Survey (KISS) is a new objective-prism survey for extragalactic emission-line objects. It combines many of the features of previous slitless sp…
On ionization effects and abundance ratios in damped Lyman alpha systems
Yuri I. Izotov, Daniel Schaerer, Corinne Charbonnel
The similarity between observed velocity structures of Al III and singly ionized species in damped Lyman-alpha systems (DLAs) suggests the presence of ionized gas in the regions wh…
The near-infrared view of SBS 0335-052
L. Vanzi, L. H. Hunt, T. X. Thuan +1
We present near-infrared (NIR) spectra, deep J, H and K low-resolution ima ges, and high-resolution images in J and Ks of the low-metallicity blue dwarf gal axy SBS 0335-052. These…
On ionisation effects and abundance ratios in damped Lyman-alpha systems
Daniel Schaerer, Yuri Izotov, Corinne Charbonnel
The similarity between observed velocity structures of Al III and singly ionised species in damped Lyman-alpha systems (DLAs) suggests the presence of ionised gas in the regions wh…
Massive star populations and the IMF in metal-rich starbursts
Daniel Schaerer, Natalia G. Guseva, Yuri I. Izotov +1
We present new spectroscopic observations of Mkn 309, a starburst galaxy with one of the largest WR populations known. A highly super solar metallicity is derived. Using additional…
The Cometary Blue Compact Dwarf Galaxies Mkn 59 and Mkn 71: Clues to Dwarf Galaxy Evolution?
K. G. Noeske, N. G. Guseva, K. J. Fricke +3
"Cometary" Blue Compact Dwarf Galaxies (iI,C BCDs) are characterized by off-center starbursts close to the end of an elongated dwarf irregular (dI)-like host galaxy. This may eithe…
The KPNO International Spectroscopic Survey. I. Description of the Survey
J. J. Salzer, C. Gronwall, V. A. Lipovetsky +7
The KPNO International Spectroscopic Survey (KISS) is a new objective-prism survey for extragalactic emission-line objects. It combines many of the features of previous slitless sp…
HS 0822+3542 - a new nearby extremely metal-poor galaxy
A. Y. Kniazev, S. A. Pustilnik, J. Masegosa +9
We present the results of spectrophotometry and BVR CCD photometry, as well as integrated HI radio measurements of a new blue compact galaxy (BCG) HS 0822+3542 with extremely low o…
Super star clusters as probes of massive star evolution and the IMF at extreme metallicities
Daniel Schaerer, Natalia G. Guseva, Yuri I. Izotov
Young super star clusters and young compact massive star forming regions can provide useful information on their burst properties (age, burst duration, SFR), the upper end of the I…
The Hamburg/SAO Survey for Emission-Line Galaxies. III. The Third List of 81 Galaxies
U. Hopp, D. Engels, R. F. Green +10
We present the third list with results {Tables 2 to 6 are available only in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.…
