چکیده

Deep ROSAT PSPC and HRI observations of the nuclear starburst, UV flat spectrum spiral NGC 6217 reveal a jet-like X-ray filament extending out 2. ′ 7 (18.8 kpc) to the SW of the galaxy. Radio images of NGC 6217 show an extent in the same direction, giving further evidence for a one-sided X-ray jet interpretation of this feature. It's X-ray spectrum is harder than that of NGC 6217 and the luminosity in the 0.5–2.0 keV band ∼1.7·10 39 erg s −1. We compare our findings to parameters of other X-ray jets from other active galaxies. We also give positions of a total of 91 X-ray sources detected in the field to a limiting 0.5–2.0 keV flux of ∼ 2.2·10 −15 erg cm −2 s −1 and propose optical and radio identifications. Some of these sources have been identified in the RIXOS program.

NGC 7679 : an anomalous , composite Seyfert 1 galaxy whose , X - ray luminous AGN vanishes at optical wavelengths . ⋆

Morphological disturbances and gas kinematics of the SB0 galaxy NGC 7679=Arp 216 are investigated to get clues to the history of this highly composite object, where AGN and starburst signatures dominate each other in the X-ray and optical/IR regime, respectively. Perturbations of the ionized gas velocity field appear quite mild within 15 (∼5 kpc) from the center, so as it can be straightforward...

The 0.3–30 Kev Spectra of Powerful Starburst Galaxies: Nustar and Chandra Observations of Ngc

We present nearly simultaneous Chandra and NuSTAR observations of two actively star-forming galaxies within 50 Mpc: NGC 3256 and NGC 3310. Both galaxies are significantly detected by both Chandra and NuSTAR, which together provide the first-ever spectra of these two galaxies spanning 0.3–30 keV. The X-ray emission from both galaxies is spatially resolved by Chandra; we find that hot gas dominat...

Recently, the CANGAROO-II telescope detected diffuse TeV gamma-ray emission from a nearby edge-on starburst galaxy, NGC 253. The emission mechanism is discussed in this report. We review the emissions of radio-to-TeV gamma-rays from NGC 253, and present a model of the non-thermal emissions due to synchrotron radiations and inverse Compton scatterings. A halo model successfully explains the mult...

A Chandra Survey of the Nearest Ulirgs: Obscured Agn or Super-starbursts?

We present initial results from a Chandra survey of a complete sample of the 8 nearest (z ≤ 0.04) ultraluminous IR galaxies (ULIRGs), and also include the IR-luminous galaxy NGC 6240 for comparison. In this paper we use the hard X-rays (2-8 kev) to search for the possible presence of an obscured AGN. In every case, a hard X-ray source is detected in the nuclear region. If we divide the sample a...

ASCA observations of type-2 Seyfert Galaxies: II The Importance of X-ray Scattering and Reflection

We discuss the importance of X-ray scattering and Compton reflection in type-2 Seyfert Galaxies, based upon the analysis of ASCA observations of 25 such sources. Consideration of the iron Kα, [Oiii] line and X-ray variability suggest that NGC 1068, NGC 4945, NGC 2992, Mrk 3, Mrk 463E and Mrk 273 are dominated by reprocessed X-rays. We examine the properties of these sources in more detail. We f...
