Probing Star Formation at Low Metallicity: the Radio Emission of Super Star Clusters in Sbs0335−052
We present high-resolution radio continuum observations of the nascent starburst in the metalpoor galaxy SBS 0335−052. These radio data were taken with the Very Large Array and include observations at 0.7 cm, 1.3 cm, 2 cm, 3.6 cm, and 6 cm. These observations enable us to probe the thermal radio nebulae associated with the extremely young star-forming regions in this galaxy. Two discrete and lu...
متن کاملLow-metallicity Blue Compact Dwarfs as Templates for Primordial Star Formation
Understanding how galaxies formed their first stars is a vital cosmological question, but the study of high-redshift objects, caught in the act of forming their first stars, is difficult. Here we argue that two extremely low-metallicity Blue Compact Dwarf galaxies (BCDs), I Zw 18 and SBS 0335-052, could be local templates for primordial star formation, since both lack evolved (> 1Gyr) stellar p...
متن کاملTo appear in ApJ Dust in an extremely metal-poor galaxy: mid-infrared observations of SBS
The metal deficient (Z = Z⊙/41) Blue Compact Dwarf Galaxy (BCD) SBS0335-052 was observed with ISOCAM between 5 and 17μm. With a L12μm/LB ratio of 2.15, the galaxy is unexpectedly bright in the mid-infrared for such a low-metallicity object. The mid-infrared spectrum shows no sign of the Unidentified Infrared Bands, which we interpret as an effect of the destruction of their carriers by the very...
متن کاملThe Extraordinary Mid-infrared Spectrum of the Blue Compact Dwarf Galaxy Sbs 0335 052
SBS0335-052 is a blue compact dwarf galaxy (BCD) with one of the lowest known metallicities, Z∼Z⊙/41, making it a local example of how primordial starburst galaxies and their precursors might appear. A spectrum obtained with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope clearly shows silicate absorption features, emission lines of [SIV] and [NeIII], and puts strong upper limits...

New infrared and millimeter observations from Keck, Palomar, ISO, and OVRO and archival data from the NRAO VLA and IRAS are presented for the low metallicity blue compact dwarf galaxy SBS 0335-052. Mid-infrared imaging shows this young star-forming system is compact (0. 31; 80 pc) at 12.5 μm. The large Brγ equivalent width (235 Å) measured from integral field spectroscopy is indicative of a ∼5 ...
