Dense cloud cores revealed by CO in the low metallicity dwarf galaxy WLM
(2015-09-10)
Understanding stellar birth requires observations of the clouds in which they form. These clouds are dense and self-gravitating, and in all existing observations they are molecular, with H2 the dominant species and carbon ...
A Warp in Progress : H I and Radio Continuum Observations of the Spiral NGC 3145
(2015-09)
We present VLA H I and 6 cm radio continuum observations of the spiral NGC 3145 and H I observations of its two companions, NGC 3143 and PGC 029578. In optical images NGC 3145 has stellar arms that appear to cross, forming ...
High-resolution mass models of dwarf galaxies from LITTLE THINGS
(2015-06)
We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. ...
