Discovery of the Radio and X-ray Counterpart of Tev Γ-ray Source Hess J1731-347
We discover a faint shell-type radio and X-ray source, G353.6-0.7, associated with HESS J1731-347. G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4 GHz and 5 GHz), infrared (8 µm from the GLIMPSE Legacy Project and 21 µm from the Midcourse Space Experiment), and X-ray (0.1 keV-2.4 keV from the ROSAT survey and 5-20 keV from the INTEGRAL survey) data. The SNR, ce...
متن کاملDiscovery of the Counterpart of Tev Γ-ray Source Hess J1731-347: a New Old Snr G353.6-0.7 with Radio and X-ray Images
We discover a new faint shell-type radio supernova remnant (SNR) G353.6-0.7 based on radio ( 1420 MHz from the Southern Galactic Plane Survey (SGPS) and 843 MHz from the Molonglo Galactic Plane Survey), infrared (8 μm from the GLIMPSE Legacy Project and 21 μm from the Midcourse Space Experiment), and X-ray (0.1 keV 2.4 keV from the ROSAT survey and 5 20 keV from the INTEGRAL survey) data. The S...
متن کاملColliding molecular clouds in head-on galaxy collisions
We present further observations of molecular gas in head-on collisions of spiral galaxies, this time of the CO(J = 1 → 0) and CO(J = 2 → 1) lines in the UGC 813 – UGC 816 system. UGC 813/6 are only the second known example of head-on spiral-spiral collisions, the first example being the UGC 12914/5 pair. Strong CO emission is present in the bridge between UGC 813 and 816, unassociated with stel...
متن کاملRadio and X-ray images of the SNR G18.8+0.3 interacting with molecular clouds
New HI images from the VLA Galactic Plane Survey (VGPS) show clear absorption features associated with supernova remnant (SNR) G18.8+0.3. High-resolution CO images reveal that molecular clouds morphologically overlap the radio filaments of G18.8+0.3. The CO emission spectrum over the full velocity range in the direction of G18.8+0.3 shows two high column density molecular clouds and three low c...
متن کاملThe Hess-philipp Model Is Non-local
Hess and Philipp have constructed what, they claim, is a local hidden variables model reproducing the empirical predictions of quantum mechanics. In this paper explicit expressions for the conditional probabilities for the outcomes of the measurements at the two detectors are calculated. These expressions provide a conclusive demonstration of the falsity of the authors’ claim. The authors give ...
