N2H+ and HC3N Observations of the Orion A Cloud
K. Tatematsu, R. Kandori, T. Umemoto +1
The ``integral-shaped filament'' of the Orion A giant molecular cloud was mapped in N2H+, and its northern end, the OMC-2/3 region was observed also in HC3N and CCS. The N2H+ distr…
Discovery of Diffuse X-ray Emission in One of the Nearest Massive Star-Forming Regions NGC 2024
Yuichiro Ezoe, Motohide Kokubun, Kazuo Makishima +2
A deep 75 ks {\it Chandra} ACIS--I data of NGC 2024 was analyzed, aiming at a search for diffuse X-ray emission in this one of the most nearby (415 pc) massive star-forming regions…
N2H+ Observations of Molecular Cloud Cores in Taurus
K. Tatematsu, T. Umemoto, R. Kandori +1
N2H+ observations of molecular cloud cores in Taurus with the Nobeyama 45 m radio telescope are reported. We compare ``cores with young stars'' with ``cores without young stars''.…
Atomic Carbon and CO Isotope Emission in the Vicinity of DR15
T. Oka, S. Yamamoto, M. Iwata +17
We present observations of the 3P1-3P0 fine structure transition of atomic carbon [CI], the J=3-2 transition of CO, as well as of the J=1-0 transitions of 13CO and C18O toward DR15…
Discovery of X rays from Class 0 protostar candidates in OMC-3
Yohko Tsuboi, Katsuji Koyama, Kenji Hamaguchi +4
We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X…
Large-scale mapping observations of the CI(3P1-3P0) and CO(J=3-2) lines toward the Orion A molecular cloud
Masafumi Ikeda, Hiroyuki Maezawa, Tetsuya Ito +14
Large scale mapping observations of the 3P1-3P0 fine structure transition of atomic carbon (CI, 492 GHz) and the J=3-2 transition of CO (346 GHz) toward the Orion A molecular cloud…
