On the density regime probed by HCN emission
Gerwyn H. Jones, Paul C. Clark, Simon C. O. Glover +1
HCN J10 emission is commonly used as a dense gas tracer, thought to mainly arise from gas with densities . This has made it a…
[CII] 158m emission from Orion A. II. Photodissociation region physics
C. H. M. Pabst, J. R. Goicoechea, A. Hacar +10
The [CII] 158m fine-structure line is the dominant cooling line of moderate-density photodissociation regions (PDRs) illuminated by moderately bright far-ultraviolet (FUV) radia…
A cold accretion flow onto one component of a multiple protostellar system
Nadia M. Murillo, Ewine F. van Dishoeck, Alvaro Hacar +2
Context: Gas accretion flows transport material from the cloud core onto the protostar. In multiple protostellar systems, it is not clear if the delivery mechanism is preferential…
The width of Herschel filaments varies with distance
G. V. Panopoulou, S. E. Clark, A. Hacar +5
Context: Filamentary structures in nearby molecular clouds have been found to exhibit a characteristic width of 0.1 pc, as observed in dust emission. Understanding the origin of th…
[CII] line emission from Orion A. I. A template for extragalactic studies?
C. H. M. Pabst, A. Hacar, J. R. Goicoechea +10
The [CII] fine-structure line is one of the dominant coolants of the neutral interstellar medium. It is hence one of the brightest far-infrared emission lines an…
A study of 90 GHz dust emissivity on molecular cloud and filament scales
Ian Lowe, Brian Mason, Tanay Bhandarkar +19
Recent observations from the MUSTANG2 instrument on the Green Bank Telescope have revealed evidence of enhanced long-wavelength emission in the dust spectral energy distribution (S…
