Chemical Evolution in High-Mass Star-Forming Regions: Results from the MALT90 Survey
Sadia Hoq, James M. Jackson, Jonathan B. Foster +7
The chemical changes of high-mass star-forming regions provide a potential method for classifying their evolutionary stages and, ultimately, ages. In this study, we search for corr…
Distinct Chemical Regions in the "Prestellar" Infrared Dark Cloud (IRDC) G028.23-00.19
Patricio Sanhueza, James M. Jackson, Jonathan B. Foster +3
We have observed the IRDC G028.23-00.19 at 3.3 mm using CARMA. In its center, the IRDC hosts one of the most massive (~1520 Msun) quiescent, cold (12 K) clumps known (MM1). The low…
The Millimeter Astronomy Legacy Team 90 GHz Survey (MALT90) and ALMA
Jonathan B. Foster, Jill M. Rathborne, James M. Jackson +3
ALMA will revolutionize our understanding of star formation within our galaxy, but before we can use ALMA we need to know where to look. The Millimeter Astronomy Legacy Team 90 GHz…
