Small Galaxies Blowing Big Bubbles
(Astronomical Society of the Pacific, 2000)
Some of the lowest-mass dwarf irregular galaxies, such as Leo A, Sag DIG and Cas 1, show a characteristic distribution of their neutral interstellar medium (ISM) as observed in the 21cm line of neutral hydrogen (HI): the ...
X-Ray Observations of Superbubbles in Dwarf Galaxies
(Revista Mexicana de Astronom a y Astrof sica, 2000)
There is plenty of evidence from neutral hydrogen observations for a violent interstellar medium, dominated by hot-plasma filled superbubbles. However, there are few direct observations of their thermal X-ray emission from ...
Massive stars shaping the ISM:Hi holes and shells in nearby galaxies
(1999)
Neutral hydrogen (H I) is a magnificent tool when studying the structure of the interstellar medium (ISM) as it is relatively easily observable and can be mapped at good spatial and velocity resolution with modern instruments. ...
VLA HI imaging of the Low Surface Brightness dwarf galaxy DDO47
(Astronomical Society of the Pacific, 1999)
We present high resolution VLA-observations of the nearby Low Surface Brightness Galaxy DDO 47. This object shows many hole-like structures in its neutral interstellar medium. The majority of the detected H I-shells are ...
Holes and shells in the interstellar medium of the nearby dwarf galaxy IC 2574
(1999)
We present H I synthesis observations of the nearby dwarf galaxy IC 2574 (a member of the M81 group of galaxies) made with the NRAO2 Very Large Array (VLA) in its B, C, and D conÐgurations at high spatial and velocity ...
Massive stars shaping the ISM:Hi holes and shells in nearby galaxies
(The International Astronomical Union, 1999)
Neutral hydrogen (H I) is a magnificent tool when studying the structure of the interstellar medium (ISM) as it is relatively easily observable and can be mapped at good spatial and velocity resolution with modern instruments. ...
X-ray emission from an expanding supergiant shell in IC 2574
(1998)
We present a multiwavelength study of a supergiant shell within the violent interstellar medium of the nearby dwarf galaxy IC 2574, which is a member of the M81 group of galaxies. Neutral hydrogen (H i) observations obtained ...
A dynamical analysis of the HII galaxy II Zwicky 33 and its low surface brightness companion
(1997)
We present radio and optical observations and an analysis of the dynamics of the H II galaxy II Zw 33 and its Low Surface Brightness companion. Both galaxies were observed in the radio with the VLA in its B- and C-array ...
