    X-ray nuclear emission of a sample of LINER Galaxies
    We report the results from an homogeneous analysis of the X-ray (ACIS-S/Chandra) data available for a sample of 52 LINER galaxies. The X-ray morphology has been...
  • Publication
    X-ray properties of AGN in CDFS (Tozzi+, 2006)
    We present a detailed X-ray spectral analysis of the sources in the 1Ms catalog of the Chandra Deep Field South (CDFS, J/ApJS/139/369) taking advantage of...
  • Publication
    X-ray re-brightening detected from the neutron star transient XTE J1701-407
    Following our recent report on the transition to quiescence of the transient neutron star low-mass X-ray binary XTE J1701-407 (ATel #3604), we continued to...
  • Publication
    X-ray Reverberation Mapping of Ci Cam
    We have analyzed the X-ray lightcurve of the star CI Cam, the optical counterpart of the X-ray transient XTE J0421+56 using data from XMM-Newton. Our motivation...
  • Publication
    X-ray Sources in M31: Source Properties and Population
    M31 is one of the best studied galaxies. At a distance of 700 kpc, it provides us with an opportunity to study the global properties of a galaxy which is...
  • Publication
    X-ray sources toward NGC 2808 (Servillat+, 2008)
    NGC 2808 was observed with the Chandra X-ray Observatory and the Chandra Advanced CCD Imaging Spectrometer-Imager (ACIS-I) at its focus on 2007 June 19-21 (28...
  • Publication
    X-ray spectral variability of LINERs selected from the Palomar sample
    Variability in active galactic nuclei (AGN) has been discovered at X-ray, UV, and radio frequencies on timescales from hours to years, being one of their most...
  • Publication
    X-ray spectral variability of low ionization nuclear emission line regions (LINERs)
    Although variability is a general property of AGN, and in LINERs variations in timescales of months/years have been found for some objects, it is not clear how...
  • Publication
    X-ray spectral variability of low-mass X-ray binaries
    The author reports on a study of the x-ray spectral variability of 37 low-mass x-ray binaries (LMXRB). The sample studied consists of all LMXRB which were...
