The soft X-ray emission components of NGC 4258 decomposed by deep ROSAT observations
Spatial, spectral, and timing analysis of deep ROSAT HRI and PSPC observations of the active spiral galaxy NGC 4258 are reported. The diffuse emission of NGC 4258 has a 0.1–2.4 keV luminosity of Lx ∼ 2 × 1040 erg s−1 (corrected for Galactic foreground absorption) and fills ∼ 40% of the D25 diameter. One half of the HRI count rate of this region is caused by a ridge of high surface brightness em...
متن کاملBeppoSAX observations of soft X-ray Intermediate Polars
We present broad-band (0.1–90 keV) spectral and temporal properties of the three Intermediate Polars, RE0751+144 (PQGem), RXJ0558.0+5353 (V405Aur) and RXJ1712.6−2414 (V2400Oph) based on simultaneous soft and hard X-ray observations with the BeppoSAX satellite. The analysis of their spectra over the wide energy range of BeppoSAX instruments allows us to identify the soft and hard X-ray component...
متن کاملSoft X-ray emission from intermediate-age open clusters: NGC6940
We present the results of soft X-ray observations of the intermediate-age open cluster NGC 6940 performed with the ROSAT PSPC. We detected 18 sources, four of which are identified with member stars of the cluster and five with active field stars. Another source is identified with an active giant star that could belong to the cluster, although it is not classified as a cluster member. The remain...
متن کاملRosat X-ray Observations of the Cooling Flow Cluster A2597
The cluster A2597 was observed in X-rays with the ROSAT PSPC and HRI detectors. The X-ray emission from the cluster extends out to a radius of at least 2.37 Mpc. The X-ray isophotes are oriented similarly to the optical isophotes of the central cD galaxy and to the isopleths of the galaxy distribution in the cluster, but are otherwise quite regular, suggesting that this cluster is reasonably re...
