The Swift gamma-ray burst mission
The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10. Expand
An X-ray spectral study of 24 type 1 active galactic nuclei
I present a study of the X-ray spectral properties of a sample containing 24 type-1 active galactic nuclei using the medium spectral resolution of ``ASCA''. The sample consists of 20 radio-quietExpand
The relation between accretion rate and jet power in X-ray luminous elliptical galaxies
Using Chandra X-ray observations of nine nearby, X-ray luminous elliptical galaxies with good optical velocity dispersion measurements, we show that a tight correlation exists between the BondiExpand
X-Ray Spectral Properties of the BAT AGN Sample
The 9-month Swift Burst Alert Telescope (BAT) catalog provides the first unbiased (NH < 1024 cm?2) look at local (z = 0.03) active galactic nuclei (AGNs). In this paper, we present the collectedExpand
Broad line emission from iron K- and L-shell transitions in the active galaxy 1H 0707-495
The combination of spectral and timing data on 1H 0707-495 provides strong evidence that the authors are witnessing emission from matter within a gravitational radius, or a fraction of a light minute, from the event horizon of a rapidly spinning, massive black hole. Expand
XMM-EPIC observation of MCG-6-30-15: direct evidence for the extraction of energy from a spinning black hole?
We present XMM-Newton European Photon Imaging Camera (EPIC) observations of the bright Seyfert 1 galaxy MCG 6-30-15, focusing on the broad Fe Kline at � 6keV and the associated reflection continuum,Expand
Wind from the black-hole accretion disk driving a molecular outflow in an active galaxy
Observations of a powerful accretion-disk wind with a mildly relativistic velocity in the X-ray spectrum of IRAS F11119+3257, a nearby optically classified type 1 ultraluminous infrared galaxy hosting a powerful molecular outflow are reported. Expand
Broad Iron Lines in Active Galactic Nuclei
An intrinsically narrow line emitted by an accretion disk around a black hole appears broadened and skewed as a result of the Doppler effect and gravitational redshift. The fluorescent iron line inExpand
Measuring Black Hole Spin Using X-Ray Reflection Spectroscopy
I review the current status of X-ray reflection (a.k.a. broad iron line) based black hole spin measurements. This is a powerful technique that allows us to measure robust black hole spins across theExpand
Irradiation of an accretion disc by a jet: general properties and implications for spin measurements of black holes
X-ray irradiation of the accretion disc leads to strong reflection features, which are then broadened and distorted by relativistic effects. We present a detailed, general relativistic approach toExpand
