The X-ray Properties of the Nearby Star-forming Galaxy Ic 342: the Xmm-newton View
We present results on the X-ray properties of IC 342 using a 10 ks XMM-Newton observation. Thirty-five sources are detected coincident with the disk of IC 342 (more than tripling the number known), of which ≈ 31 are likely to be intrinsic to IC 342. This point-source population exhibits a diverse range of spectral properties and has an X-ray luminosity function slope and infrared luminosity com...
متن کاملXMM - Newton observation of the X - ray point source population of the starburst galaxy IC 342
We present the results of an XMM-Newton observation of the starburst galaxy IC 342. Thirty-seven X-ray point sources were detected down to a luminosity limit of ∼ 10 erg s. Most of the sources are located near the spiral arms. The X-ray point source luminosity function is consistent with a power-law shape with a slope of 0.55, typical of starburst galaxies. We also present the energy spectra of...
متن کاملWater maser emission in IC 342
The detection of 22GHz water vapor emission from IC 342 is reported, raising the detection rate among northern galaxies with IRAS point source fluxes S100μm > 50 Jy to 16%. The maser, associated with a star forming region ∼10–15 west of the nucleus, consists of a single 0.5 kms wide feature and reaches an isotropic luminosity of 10 L⊙ (D=1.8Mpc). If the time variability is intrinsic, the maser ...
متن کاملThe unusual supernova remnant surrounding the ultraluminous X - ray source IC 342 X - 1
We report the results of an observation of a large diameter (110 pc) supernova remnant (SNR) found to encircle the position of the ultraluminous X-ray source (ULX) IC 342 X-1. The inferred initial energy input to the SNR is at least 2 – 3 times greater than the canonical energy for an “ordinary” supernova remnant. Two regions on the inside of the shell are bright in [OIII] λ5007 emission, possi...
متن کاملSpatially Resolved Chemistry in Nearby Galaxies. I. the Center of Ic 342
We have imaged emission from the millimeter lines of eight molecules—C2H, C S, N2H , CH3OH, HNCO, HNC, HC3N, and SO—in the central half-kiloparsec of the nearby spiral galaxy IC 342. The 5 00 ( 50 pc) resolution images were made with the Owens Valley Millimeter Array. Using these and previously published CO and HCN images, we obtain a picture of the chemistry within the nuclear region on the si...
