Deep spectroscopy of the low - metallicity blue compact dwarf galaxy SBS 0335 – 052 ⋆
The results of deep long-slit spectroscopy of the extremely low-metallicity blue compact dwarf (BCD) galaxy SBS 0335–052 are presented. Down to intensity levels of 10 of Hβ, unprecedented for spectroscopy of extra-galactic giant H ii regions, we detect numerous weak permitted and forbidden nebular lines in the brightest part of the galaxy. With varying degrees of confidence, the detections incl...
متن کامل2 00 8 Super Star Clusters in SBS 0335 - 052
As one of the lowest metallicity star forming galaxies, with a nucleus of several super star clusters, SBS0335-052E is the subject of substantial current study.
متن کاملSbs 0335–052w: the Lowest-metallicity Star-forming Galaxy Known
We present 4-meter Kitt Peak telescope and 6.5-meter MMT spectrophotometry of the extremely low-metallicity galaxy SBS 0335–052W, the western companion of the blue compact dwarf galaxy SBS 0335–052E. These observations have been combined with published 10-meter Keck data to derive for the brightest region of SBS 0335– 052W an oxygen abundance 12 + log O/H = 7.12 ± 0.03. This makes SBS 0335–052W...
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...
متن کاملHst Observations of the Blue Compact Dwarf Sbs 0335–052: a Probable Young Galaxy
We present HST WFPC2 V and I images and GHRS UV spectrophotometry of the spectral regions around Lyα and OI λ1302 of the extremely metal-deficient ( Z ∼ Z⊙/41 ) blue compact dwarf (BCD) galaxy SBS 0335–052. All the star formation in the BCD occurs in six superstar clusters (SSC) with ages ≤ 3-4 Myr. As there is no evident sign of tidal interaction, star formation in the BCD is probably triggere...
