Extended HNCO, SiO, and HC3N Emission in 43 Southern Star-forming Regions

Shocks are a ubiquitous phenomenon in the interstellar medium (ISM) of galaxies. They may be driven by supernova explosions, the pressure of photoionized gas, stellar winds, and collisions between fast-moving clumps of interstellar gas, ...

Ammonia observations towards the Aquila Rift cloud complex

Ammonia (NH3) is frequently used as the standard molecular cloud thermometer (e.g., Ho & Townes 1983; Walmsley & Ungerechts 1983). NH3 (1,1) and (2,2), both belonging to the para-species of ammonia, have been proven to be an excellent th...
