A Metallicity Map of M33
Joshua D. Simon, Erik Rosolowsky
We present initial results from the M33 Metallicity Project. Out of the thousands of cataloged HII regions in M33, only ~30 have electron-temperature based abundances in the litera…
The M33 Metallicity Project: Resolving the Abundance Gradient Discrepancies in M33
Erik Rosolowsky, Joshua D. Simon
We present a new determination of the metallicity gradient in M33, based on Keck/LRIS measurements of oxygen abundances using the temperature-sensitive emission line [OIII] 4363 A…
An Ammonia Spectral Atlas of Dense Cores in Perseus
E. W. Rosolowsky, J. E. Pineda, J. B. Foster +5
We present ammonia observations of 193 dense cores and core candidates in the Perseus molecular cloud made using the Robert F. Byrd Green Bank Telescope. We simultaneously observed…
A Catalog of HI Clouds in the Large Magellanic Cloud
S. Kim, E. Rosolowsky, Y. Lee +9
A 21 cm neutral hydrogen interferometric survey of the Large Magellanic Cloud (LMC) combined with the Parkes multi-beam HI single-dish survey clearly shows that the HI gas is distr…
Hierarchical Star-Formation in M33: Fundamental properties of the star-forming regions
N. Bastian, B. Ercolano, M. Gieles +4
Star-formation within galaxies appears on multiple scales, from spiral structure, to OB associations, to individual star clusters, and often sub-structure within these clusters. Th…
High Resolution Molecular Gas Maps of M33
E. Rosolowsky, E. Keto, S. Matsushita +1
New observations of CO (J=1->0) line emission from M33, using the 25 element BEARS focal plane array at the Nobeyama Radio Observatory 45-m telescope, in conjunction with existing…
