A Small X-ray Corona of the Narrow-angle Tail Radio Galaxy Ngc 1265 Soaring through the Perseus Cluster
A deep Chandra observation of NGC 1265 (3C 83.1B), the prototype for the narrow-angled-tailed (NAT) radio galaxy, reveals a small cool X-ray thermal corona (∼ 0.6 keV) embedded in the hot ICM of the Perseus cluster (∼ 6.7 keV). The corona is asymmetric with a sharp edge (∼2.2, or 0.8 kpc from the nucleus) to the south and an extension to the north (at least ∼ 8 from the nucleus), which is inter...
متن کاملMolecular Gas in the Perseus Cooling Flow Galaxy , NGC 1275
The central arcminute of the Perseus cooling flow galaxy, NGC 1275, has been mapped with the JCMT in CO(2–1) at 21 resolution, with detections out to at least 36 (12 kpc). Within the limits of the resolution and coverage, the distribution of gas appears to be roughly E-W, consistent with previous observations of CO, X-ray, Hα, and dust emission. The total detected molecular hydrogen mass is ∼ 1...
متن کاملMagic Gamma-ray Observation of the Perseus Galaxy Cluster
The Perseus galaxy cluster was observed by the MAGIC Cherenkov telescope for a total effective time of 24.4 hours during November and December 2008. The resulting upper limits on the γ-ray emission above 100 GeV are in the range of 4.6 to 7.5× 10cm s for spectral indices from −1.5 to −2.5; thereby constraining the emission produced by cosmic rays, dark matter annihilations, and the central radi...
متن کاملTeV γ - Ray Observations of the Perseus Galaxy Cluster
We report on observations of the Perseus cluster of galaxies using the 10 m Whipple γ-ray telescope during the 2004-2005 observing season. We apply a two dimensional analysis technique to allow us to scrutinize the cluster for TeV emission. In this contribution we will first calculate flux upper limits on TeV γ-ray sources within the cluster. Second, we derive an upper limit on the extended clu...
متن کاملA Wide Angle Tail Radio Galaxy in the Cosmos Field: Evidence for Cluster Formation
We have identified a complex galaxy cluster system in the COSMOS field via a wide angle tail (WAT) radio galaxy consistent with the idea that WAT galaxies can be used as tracers of clusters. The WAT galaxy, CWAT-01, is coincident with an elliptical galaxy resolved in the HST-ACS image. Using the COSMOS multiwavelength data set, we derive the radio properties of CWAT-01 and use the optical and X...
