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…
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…
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…
