[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…
4GREAT -- a four-color receiver for high-resolution airborne terahertz spectroscopy
Carlos A. Durán, Rolf Güsten, Christophe Risacher +13
4GREAT is an extension of the German Receiver for Astronomy at Terahertz frequencies (GREAT) operated aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA). The spect…
NGC7538 IRS1 -- an O star driving an ionized jet and giant N-S outflow
G. Sandell, M. Wright, R. Güsten +4
NGC 7538 IRS 1 is a very young embedded O star driving an ionized jet and accreting mass with an accretion rate > 10^-4 Msun/year, which is quenching the hypercompact HII region. W…
Anatomy of the massive star-forming region S106: The OI 63 micron line observed with GREAT/SOFIA as a versatile diagnostic tool for the evolution of massive stars
N. Schneider, M. Roellig, R. Simon +9
The central area (40"x40") of the bipolar nebula S106 was mapped in the OI line at 63.2 micron with high angular (6") and spectral resolution, using GREAT on board SOFIA. The OI em…
C^+ distribution around S1 in rho Ophiuchi
B. Mookerjea, G. Sandell, W. Vacca +2
We analyze a [C II] 158 micron map obtained with the L2 GREAT receiver on SOFIA of the emission/reflection nebula illuminated by the early B star S1 in the rho-OphA cloud core. Thi…
Warm ISM in the Sgr A Complex. I: Mid-J CO, atomic carbon, ionized atomic carbon,and ionized nitrogen sub-mm/FIR line observations with the Herschel-HIFI and NANTEN2/SMART telescopes
P. García, R. Simon, J. Stutzki +3
We present large-scale submm observations towards the Sgr A Complex covering ~300 arcmin2. These data were obtained in the frame of the HEXGAL Program with the Herschel-HIFI satell…
Carbon gas in SMC low-metallicity star-forming regions
M. A. Requena-Torres, F. P. Israel, Y. Okada +5
This paper presents [CII], [CI] and CO emission line maps of the star-forming regions N66, N25+N26, and N88 in the metal-poor Local Group dwarf galaxy SMC. The spatial and velocity…
The 2nd Generation z(Redshift) and Early Universe Spectrometer Part I: First-light observation of a highly lensed local-ULIRG analog at high-z
Carl Ferkinhoff, Drew Brisbin, Stephen Parshley +20
We report first science results from our new spectrometer, the 2nd generation z(Redshift) and Early Universe Spectrometer (ZEUS-2), recently commissioned on the Atacama Pathfinder…
SOFIA observations of S106: Dynamics of the warm gas
Robert Simon, Nicola Schneider, Juergen Stutzki +6
Context. The HII region/PDR/molecular cloud complex S106 is excited by a single O-star. The full extent of the warm and dense gas close to the star has not been mapped in spectrall…
Herschel observations of extra-ordinary sources: Detection of Hydrogen Fluoride in absorption towards Orion~KL
T. G. Phillips, E. A. Bergin, D. C. Lis +52
We report a detection of the fundamental rotational transition of hydrogen fluoride in absorption towards Orion KL using Herschel/HIFI. After the removal of contaminating features…
Herschel observations in the ultracompact HII region Mon R2: Water in dense Photon-dominated regions (PDRs)
A. Fuente, O. Berne, J. Cernicharo +42
Mon R2, at a distance of 830 pc, is the only ultracompact HII region (UC HII) where the photon-dominated region (PDR) between the ionized gas and the molecular cloud can be resolve…
Excitation of the molecular gas in the nuclear region of M82
A. F. Loenen, P. P. van der Werf, R. Güsten +23
We present high resolution HIFI spectroscopy of the nucleus of the archetypical starburst galaxy M82. Six 12CO lines, 2 13CO lines and 4 fine-structure lines are detected. Besides…
Black hole accretion and star formation as drivers of gas excitation and chemistry in Mrk231
P. P. Van der Werf, K. G. Isaak, R. Meijerink +34
We present a full high resolution SPIRE FTS spectrum of the nearby ultraluminous infrared galaxy Mrk231. In total 25 lines are detected, including CO J=5-4 through J=13-12, 7 rotat…
