CII fine-structure line observations of the Sagittarius C Region in the Galaxy's Central Molecular Zone
DEnise Riquelme-Vasquez, Rolf Guesten, Mark R. Morris +7
Context. Sagittarius C (Sgr C) is a massive, relatively quiescent complex at the western edge of the Galaxy's Central Molecular Zone (CMZ). While the Sgr B2 region has been extensi…
Detection of interstellar ortho-D2H+ with SOFIA
Jorma Harju, Olli Sipilä, Sandra Brünken +9
We report on the detection of the ground-state rotational line of ortho-D2H+ at 1.477 THz (203 micron) using the German REceiver for Astronomy at Terahertz frequencies (GREAT) onbo…
The effect of sideband ratio on line intensity for Herschel/HIFI
Ronan Higgins, David Teyssier, Colin Borys +8
The Heterodyne Instrument for the Far Infrared (HIFI) on board the Herschel Space Observatory is composed of a set of fourteen double sideband mixers. We discuss the general proble…
Bright-rimmed clouds in IC 1396 I. Dynamics
Yoko Okada, Slawa Kabanovic, Rolf Güsten +14
We investigate the dynamical and physical structures of bright-rimmed clouds (BRCs) in a nearby HII region. We focused on carbon- and oxygen-bearing species that trace photon-domin…
Astro2020: The Cycling of Matter from the Interstellar Medium to Stars and back
Robert Simon, Nicola Schneider, Frank Bigiel +15
Understanding the matter cycle in the interstellar medium of galaxies from the assembly of clouds to star formation and stellar feedback remains an important and exciting field in…
An overview of the planned CCAT software system
Tim Jenness, Martin C. Shepherd, Reinhold Schaaf +7
CCAT will be a 25m diameter sub-millimeter telescope capable of operating in the 0.2 to 2.1mm wavelength range. It will be located at an altitude of 5600m on Cerro Chajnantor in no…
First detection of [13CII] in the Large Magellanic Cloud
Yoko Okada, Ronan Higgins, Volker Ossenkopf-Okada +3
[13CII] observations in several Galactic sources show that the fine-structure [12CII] emission is often optically thick (the optical depths around 1 to a few). The aim of our study…
