H. E. S. S. Collaboration, :, H. Abdalla +263
A search for new supernova remnants (SNRs) has been conducted using TeV gamma-ray data from the H.E.S.S. Galactic plane survey. As an identification criterion, shell morphologies t…
Herschel spectroscopy of Massive Young Stellar Objects in the Magellanic Clouds
J. M. Oliveira, J. Th. van Loon, M. Sewilo +11
We present Herschel Space Observatory Photodetector Array Camera and Spectrometer (PACS) and Spectral and Photometric Imaging Receiver Fourier Transform Spectrometer (SPIRE FTS) sp…
Detailed molecular observations toward the Double Helix Nebula
K. Torii, R. Enokiya, M. R. Morris +3
The Double Helix Nebula (DHN), located 100 pc above Sgr A* in the Galactic center (GC), is a unique structure whose morphology suggests it is a magnetic feature (Morris, Uchida & D…
Molecular clouds in the Trifid nebula M20; Possible evidence for a cloud-cloud collision in triggering the formation of the first generation stars
K. Torii, R. Enokiya, H. Sano +14
A large-scale study of the molecular clouds toward the Trifid nebula, M20, has been made in the J=2-1 and J=1-0 transitions of 12CO and 13CO. M20 is ionized predominantly by an O7.…
Discovery of possible molecular counterparts to the infrared Double Helix Nebula in the Galactic center
R. Enokiya, K. Torii, M. Schultheis +23
We have discovered two molecular features at radial velocities of -35 km/s and 0 km/s toward the infrared Double Helix Nebula (DHN) in the Galactic center with NANTEN2. The two fea…
Discovery of a giant molecular loop in the central region of NGC 253
R. Konishi, R. Enokiya, Y. Fukui +3
NGC 253 is a starburst galaxy of SAB(s)c type with increasing interest because of its high activity at unrivaled closeness. Its energetic event is manifested as the vertical gas fe…
Large-scale mapping of the massive star-forming region RCW38 in the [CII] and PAH emission
H. Kaneda, T. Nakagawa, S. K. Ghosh +10
We investigate the large-scale structure of the interstellar medium (ISM) around the massive star cluster RCW38 in the [CII] 158 um line and polycyclic aromatic hydrocarbon (PAH) e…
Modeling the gamma-ray emission produced by runaway cosmic rays in the environment of RX J1713.7-3946
S. Casanova, D. I. Jones, F. A. Aharonian +8
Diffusive shock acceleration in supernova remnants is the most widely invoked paradigm to explain the Galactic cosmic ray spectrum. Cosmic rays escaping supernova remnants diffuse…
Sub-millimeter Observations of Giant Molecular Clouds in the Large Magellanic Cloud: Temperature and Density as Determined from J=3-2 and J=1-0 transitions of CO
T. Minamidani, N. Mizuno, Y. Mizuno +26
We have carried out sub-mm 12CO(J=3-2) observations of 6 giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10m sub-mm telescope at a spatial resolutio…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over se…
