The X–ray Background: Observations

X-ray observations of ultraluminous X-ray sources

Ultraluminous X-ray sources (ULXs) are amongst the most intriguing of X-ray source classes. Their extreme luminosities greater than 10 erg s in the 0.3 – 10 keV band alone suggest either the presence of black holes larger than those regularly encountered in our own Galaxy (the Galactic centre excepted), or sources apparently radiating well above the Eddington limit. We review the insights affor...

Simultaneous X-ray/radio Observations of Cir X-1 Simultaneous X-ray/radio Observations of Cir X-1

We analysed simultaneous X-ray/radio observations of Circinus X-1 collected respectively with RXTE and ATCA in 2000 October and 2002 December and identified radio flares close to phase 0.0 and 0.5 of the orbital period. To date, there is only circumstantial evidence for radio flares near phase 0.5. Moreover, in our data set, we clearly associated both a radio flare and X-ray spectral timing cha...

X-Ray Observations on the Galactic Center Region

This paper reports on the early Chandra view of the Galactic center (GC) activities. The massive black hole Sgr A is extremely faint, while more bright diffuse X-ray emission is prevailing in the circumnuclear disk. Another high temperature plasma is found in the Sgr A East shell. This may indicate that Sgr A East is a supernova remnant, although no clear X-ray shell is found. A hint of non-the...
