ChandraView of the Dynamically Young Cluster of Galaxies A1367. II. Point Sources

A 40 ks \emph{Chandra} ACIS-S observation of the dynamically young clusterA1367 yields new insights on X-ray emission from cluster member galaxies. Wedetect 59 point-like sources in the ACIS field, of which 8 are identified withknown cluster member galaxies. Thus, in total 10 member galaxies are detectedin X-rays when three galaxies discussed in paper I (Sun & Murray 2002; NGC 3860is discussed in both papers) are included. The superior spatial resolution andgood spectroscopy capability of \chandra allow us to constrain the emissionnature of these galaxies. Central nuclei, thermal halos and stellar componentsare revealed in their spectra. Two new low luminosity nuclei (LLAGN) are found,including an absorbed one (NGC 3861). Besides these two for sure, two newcandidates of LLAGN are also found. This discovery makes the LLAGN/AGN contentin this part of A1367 very high ($\gsim$ 12%). Thermal halos with temperaturesaround 0.5 - 0.8 keV are revealed in the spectra of NGC 3842 and NGC 3837,which suggests that Galactic coronae can survive in clusters and heatconduction must be suppressed. The X-ray spectrum of NGC 3862 (3C 264)resembles a BL Lac object with a photon index of $\sim$ 2.5. We also present ananalysis of other point sources in the field and discuss the apparent sourceexcess ($\sim$ 2.5 $\sigma$) in the central field.Comment: To appear in ApJ, 2002, Vol 57
