Detection of neutral hydrogen in early-type dwarf galaxies of the Sculptor Group
Antoine Bouchard, Helmut Jerjen, Gary S. Da Costa +1
We present our results of deep 21 cm line (HI) observations of five early and mixed-type dwarf galaxies in the nearby Sculptor group using the ATNF 64m Parkes Radio Telescope. Four…
The Temperature Distribution of Dense Molecular Gas in the Center of NGC 253
Juergen Ott, Axel Weiss, Christian Henkel +1
[abridged] We present interferometric maps of ammonia (NH3) of the nearby starburst galaxy NGC 253 [star formation rate: ~2.8 Mo yr^(-1)]. The observations have been taken with the…
A Chandra X-ray survey of nearby dwarf starburst galaxies: II. Starburst properties and outflows
Juergen Ott, Fabian Walter, Elias Brinks
(abridged) We present a comprehensive comparison of the X-ray properties of a sample of eight dwarf starburst galaxies observed with Chandra (I Zw 18, VII Zw 403, NGC 1569, NGC 307…
