84-GHz methanol masers, their relationship to 36-GHz methanol masers and their molecular environments
Shari Breen, Yanett Contreras, Joanne Dawson +3
We present observations of the 36- (4_-1 -> 3_0E) and 84-GHz (5_-1 -> 4_0 E) class I methanol maser transitions towards a sample of 94 known class I sites. These observations resul…
G337.342-0.119 (the "Pebble"): A Cold, Dense, High-Mass Molecular Cloud with Unusually Large Linewidths and a Candidate High-Mass Star Cluster Progenitor
James M. Jackson, Yanett Contreras, Jill M. Rathborne +7
Exactly how high-mass star clusters form, especially the young massive clusters (YMCs: age Myr; mass solar masses), remains an open problem, largely because they are…
SuperMALT: Physical and Chemical Properties of Massive and Dense Clumps
Sudeep Neupane, Guido Garay, Yanett Contreras
The SuperMALT survey is observing 76 MALT90 clumps at different evolutionary stages (from pre-stellar or quiescent to HII) in high excitation molecular lines and key isotopomers us…
Infall Signatures in a Prestellar Core embedded in the High-Mass 70 m Dark IRDC G331.372-00.116
Yanett Contreras, Patricio Sanhueza, James M. Jackson +14
Using Galactic Plane surveys, we have selected a massive (1200 M), cold (14 K) 3.6-70 m dark IRDC G331.372-00.116. This IRDC has the potential to form high-mass stars an…
Distributed star formation throughout the Galactic Center cloud Sgr B2
A. G. Ginsburg, John Bally, Ashley Barnes +23
We report ALMA observations with resolution " at 3 mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are…
