Evidences for an expanding shell in the blue compact dwarf galaxy Haro 2
Long-slit observations of the blue compact galaxy Haro 2 have been performed around Hα and Hβ. The main aim of these observations was to detect the Hα emission originating in the partially ionized wind outflowing at 200 km/s, that had been previously detected with the Hubble Space Telescope (HST). A shallow broadening of the Hα line wings has been observed, consistent with the existence of an e...
متن کاملLWS spectroscopy of the luminous blue compact galaxy Haro 11 ?
We present the results of far infrared (FIR) spec-troscopy of the luminous blue compact galaxy (BCG) Haro 11 (ESO 350-IG38) obtained with the Long Wavelength Spectrometer (LWS) on the Infrared Space Observatory (ISO) in low resolution mode. This metal poor dwarf merger is an extremely hot IRAS source. We discuss the balance between dust and line cooling in the photodissociated regions (PDR), in...
متن کاملMolecular gas in blue compact dwarf galaxies
Blue compact dwarf galaxies (BCDGs) are currently undergoing strong bursts of star formation. Nevertheless, only a few of them have been clearly detected in CO, which is thought to trace the ”fuel” of star formation: H2. In this paper we present a deep search for CO J = 1 → 0 and J = 2 → 1 emission lines in a sample of 8 BCDGs and two companions. Only 2 of them (Haro 2 and UM465) are detected. ...
متن کاملThe Discovery of the Smallest Blue Compact Dwarf Galaxies
In a spectroscopic survey of the Fornax cluster to BJ = 17.5 using the FLAIR spectrograph on the UK Schmidt Telescope we have discovered seven new compact dwarf cluster members. These were previously thought to be giant background spirals. These new members are among the most compact, high surface brightness dwarf galaxies known with absolute magnitudes of MB ≈ −14 and scale lengths of α ≈ 400 ...
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...
