Extreme X - ray variability in the luminous quasar PDS 456
We present evidence from BeppoSAX and XMM-Newton of extreme X-ray variability in the high luminosity radio-quiet quasar PDS 456, the most luminous known AGN at z < 0.3. Repeated X-ray flaring is found in PDS 456, over the duration of the 340 ksec long BeppoSAX observation. The X-ray flux doubles in just 30 ksec, whilst the total energy output of the flaring events is as high as 10 51 erg. Under...
متن کاملA Massive X-ray Outflow from the Quasar Pds 456
We report on XMM-Newton spectroscopic observations of the luminous radio-quiet quasar PDS 456. The hard X-ray spectrum of PDS 456 shows a deep absorption trough (constituting 50% of the continuum) at energies above 7 keV in the quasar rest frame, which can be attributed to a series of blueshifted K-shell absorption edges due to highly ionized iron. The higher resolution soft X-ray Reflection Gr...
متن کاملThe Connection between Ultraviolet and X - ray Outflows in AGN : the case of PDS 456
High-velocity outflows from AGN are a well-known phenomena in terms of the Broad Absorption Lines seen in the UV/optical. More recently, similar, possibly related, outflows have been reported in the X-ray. The most extreme example is seen in the nearby, luminous QSO PDS 456, which displays a massive, high velocity (50000 km s), high-ionization X-ray outflow of 10M⊙ yr . Here we present the UV s...
متن کاملSupergiant X-ray binaries observed by Suzaku
Suzaku observations are presented for the high-mass X-ray binaries IGR 116207-5129 and IGR 117391-3021. For IGR 116207-5129, we provide the first X-ray broadband (0.5-60 keY) spectrum from which we confirm a large intrinsic column density (NH = 1.6 X 1023 cm-2), and we constrain the cutoff energy for the first time (Ecut = 19 keY). A prolonged (> 30 ks) attenuation of the X-ray flux was observe...
متن کاملPDS 456 : an Extreme Accretion Rate Quasar ?
We present quasi-simultaneous ASCA and RXTE observations of the most luminous known AGN in the local (z < 0.3) universe, the recently discovered quasar PDS 456. Multiwavelength observations have been conducted which show that PDS 456 has a bolometric luminosity of ∼ 10 erg s peaking in the UV part of the spectrum. In the X-ray band the 2-10 keV (rest-frame) luminosity is 10 erg s. The broad-ban...
