Evidence of a Broad Relativistic Iron Line from the Neutron Star Low-Mass X-ray Binary Serpens X-1
We report on an analysis of XMM-Newton data from the neutron star low mass X-ray binary (LMXB) Serpens X-1 (Ser X-1). Spectral analysis of EPIC PN data indicates that the previously known broad iron Kα emission line from this source has a significantly skewed structure with a moderately extended red wing. The asymmetric shape of the line is well described with the laor and diskline models in XS...
متن کاملA Good Long Look at the Black Hole Candidates LMC X-1 and LMC X-3
LMC X-1 and LMC X-3 are the only known persistent stellar-mass black hole candidates that have almost always shown spectra that are dominated by a soft, thermal component. We present here results from 170ksec long Rossi X-ray Timing Explorer (RXTE) observations of these objects, taken in 1996 December, where their spectra can be described by a disc black body plus an additional soft (Γ ∼ 2.8) h...
متن کاملVariation of the broad X-ray iron line in MCG–6-30-15 during a flare
We report results on the broad iron emission line of the Seyfert galaxy MCG–6-30-15, obtained from the second long ASCA observation in 1997. The time-averaged profile of the broad line is very similar to that seen with ASCA in 1994, so confirming the detailed model fit then obtained. A bright flare is seen in the light curve, during which the continuum was soft. At that time the emission line p...
متن کاملBlack Hole X-ray Binary LMC X–1 and LMC X–3: Observations Confront Spectral Models
We present a comprehensive spectral analysis of black hole X-ray binaries, LMC X–1 and LMC X–3, based on BeppoSAX observations. We test both the multi-color disk plus power law (MCD+PL) model and a newly-developed Monte-Carlo simulationbased model for a Comptonized MCD (CMCD) with either a spherical or a slab-like corona, by comparing the inferred parameters with independent direct measurements...
متن کاملBroad iron L-line and X-ray reverberation in 1H0707-495
A detailed analysis of a long XMM-Newton observation of the Narrow Line Seyfert 1 galaxy 1H0707-495 is presented, including spectral fitting, spectral variability and timing studies. The two main features in the spectrum are the drop at ∼ 7 keVand a complex excess below 1 keV . These are well described by two broad, K and L, iron lines. Alternative models based on absorption, although they may ...
