Triggered star formation and the creation of the supergiant HI shell in IC 2574
(2009)
Based on deep imaging from the Advanced Camera for Surveys aboard the Hubble Space Telescope (HST), we present new evidence that stellar feedback created a similar to 1 kpc supergiant Hi shell (SGS) and triggered star ...
Bloated Dwarfs: The Thickness of the HI Disks in Irregular Galaxies
(Astronomical Society of the Pacific, 2002)
Somewhat counterintuitively, the gas disks of (dwarf) irregular galaxies, such as the LMC, are thicker than those of normal disk galaxies, both in relative as well as in absolute terms. In retrospect, this is easily ...
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 ...
