The evolutionary status of the low - metallicity blue compact dwarf galaxy SBS 0940 + 544
We present the results of spectrophotometry and V,R, I , Hα CCD photometry of the blue compact dwarf (BCD) galaxy SBS 0940+544. Broad-band images taken with the 2.1m KPNO and 1.23m Calar Alto telescopes reveal a compact high-surface-brightness H ii region with ongoing star formation, located at the northwestern tip of the elongated low surface brightness (LSB) main body of the BCD. Very faint, ...
متن کاملDeep 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 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...
متن کاملVLT / GIRAFFE spectroscopic observations of the metal - poor blue compact dwarf galaxy SBS 0335 – 052 E ⋆ ⋆ ⋆
Aims. We present two-dimensional spectroscopy of the extremely metal-deficient blue compact dwarf (BCD) galaxy SBS 0335–052E aiming to study physical conditions, element abundances and kinematical properties of the ionised gas in this galaxy. Methods. Observations were obtained in the spectral range λ3620 – 9400Å with the imaging spectrograph GIRAFFE installed on the UT2 of the Very Large Teles...
متن کاملFUSE observations of the Blue Compact Dwarf Galaxy Mrk 59
New FUSE far-UV spectroscopy of the nearby metal-deficient (Z⊙/8) cometary Blue Compact Dwarf (BCD) galaxy Markarian (Mrk) 59 is discussed. The data are used to investigate element abundances in its interstellar medium. The H i absorption lines are characterized by narrow cores which are interstellar in origin and by broad wings which are stellar in origin. The mean interstellar H i column dens...
