SOFIA/upGREAT imaging spectroscopy of the [C II] 158 um fine structure line toward the Sgr A region in the Galactic center
A. I. Harris, R. Güsten, M. A. Requena-Torres +8
We present SOFIA/upGREAT velocity-resolved spectral imaging and analysis of the 158 um [C II] spectral line toward the central 80 by 43\,pc region of the Central Molecular Zone of…
Imaging of single barium atoms in a second matrix site in solid xenon for barium tagging in a Xe double beta decay experiment
M. Yvaine, D. Fairbank, J. Soderstrom +134
Neutrinoless double beta decay is one of the most sensitive probes for new physics beyond the Standard Model of particle physics. One of the isotopes under investigation is $^{136}…
FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation
N. Schneider, R. Simon, C. Guevara +37
FEEDBACK is a SOFIA legacy program dedicated to study the interaction of massive stars with their environment. It performs a survey of 11 galactic high mass star forming regions in…
74 MHz Nonthermal Emission from Molecular Clouds: Evidence for a Cosmic Ray Dominated Region at the Galactic Center
F. Yusef-Zadeh, M. Wardle, D. Lis +5
We present 74 MHz radio continuum observations of the Galactic center region. These measurements show nonthermal radio emission arising from molecular clouds that is unaffected by…
Observation and calibration strategies for large-scale multi-beam velocity-resolved mapping of the [CII] emission in the Orion molecular cloud
R. Higgins, S. Kabanovic, C. Pabst +15
Context. The [CII] 158micron far-infrared fine-structure line is one of the dominant cooling lines of the star-forming interstellar medium (ISM). Hence [CII] emission originates in…
Disruption of the Orion Molecular Core 1 by the stellar wind of the massive star Ori C
C. Pabst, R. Higgins, J. R. Goicoechea +10
Massive stars inject mechanical and radiative energy into the surrounding environment, which stirs it up, heats the gas, produces cloud and intercloud phases in the interstellar me…
Velocity resolved [O I] 63 m emission in the HD 50138 circumstellar disk
G. Sandell, C. Salyk, M. van den Ancker +5
HH 50138 is one of the brightest B[e] stars at a distance of 380 pc with strong infrared excess. The star was observed in [O I] 63 m and [C II] 158 m with high veloc…
Opening the Treasure Chest in Carina
B. Mookerjea, G. Sandell, R. Guesten +3
We have mapped the G287.84-0.82 cometary globule (with the Treasure Chest cluster embedded in it) in the South Pillars region of Carina (i) in [CII], 63micron [OI], and CO(11-10) u…
Molecular cloud dispersal traced by the ionized carbon 158 micron line
L. Bonne, N. Schneider, S. Dannhauer +14
Feedback from massive stars in the form of radiation and winds impacts the associated host molecular cloud. Feedback can disperse cloud material and lead to the destruction of the…
An integrated online radioassay data storage and analytics tool for nEXO
R. H. M. Tsang, A. Piepke, S. Al Kharusi +157
Large-scale low-background detectors are increasingly used in rare-event searches as experimental collaborations push for enhanced sensitivity. However, building such detectors, in…
Supernova electron-neutrino interactions with xenon in the nEXO detector
nEXO Collaboration, S. Hedges, S. Al Kharusi +144
Electron-neutrino charged-current interactions with xenon nuclei were modeled in the nEXO neutrinoless double- decay detector (~5 metric ton, 90% Xe, 10% Xe…
Unveiling the formation of the massive DR21 ridge
L. Bonne, S. Bontemps, N. Schneider +10
We present new CO(1-0), CO(1-0), HCO(1-0) and HCO(1-0) maps from the IRAM 30m telescope, and a spectrally-resolved [CII] 158 m map observed wit…
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…
