The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies
K. M. Sandstrom, A. K. Leroy, F. Walter +42
We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…
The Optical Depth of H II Regions in the Magellanic Clouds
E. W. Pellegrini, M. S. Oey, P. F. Winkler +4
We exploit ionization-parameter mapping as a powerful tool to measure the optical depth of star-forming HII regions. Our simulations using the photoionization code CLOUDY and our n…
Gemini GMOS spectroscopy of HeII nebulae in M33
C. Kehrig, M. S. Oey, P. A. Crowther +6
We have carried out a narrow-band survey of the Local Group galaxy, M33, in the HeII4686 emission line, to identify HeII nebulae in this galaxy. With spectroscopic follow-up observ…
