    X-ray spectral evolution of SAX J1747.0-2853 during outburst activity and confirmation of its transient nature
    SAX J1747.0-2853 is an X-ray transient which exhibited X-ray outbursts yearly between 1998 and 2001, and most probably also in 1976. The outburst of 2000 was...

    X-ray spectral properties of active galactic nuclei in the Chandra Deep Field South
    We present a detailed X-ray spectral analysis of the sources in the 1Ms catalog of the Chandra Deep Field South (CDFS) taking advantage of optical spectroscopy...

    X-ray Spectral State is not Correlated with Luminosity in Holmberg II X-1
    The ultraluminous X-ray source (ULX) Holmberg II X-1 has been observed over four months in 2009/2010 by the Swift observatory. The source luminosity varied by a...
  • Publication
    X-ray spectral variability of LINERs selected from the Palomar sample
    Context. Variability is a general property of active galactic nuclei (AGN). The way in which these changes occur at X-rays is not yet clearly understood. In the...
  • Publication
    X-ray spectral variability of seven LINER nuclei with XMM-Newton and Chandra data
    Context. One of the most distinctive features in active galactic nuclei (AGN) is the variability of their emission. Variability has been discovered at X-ray, UV...

    X-Ray States of Redback Millisecond Pulsars
    Compact binary millisecond pulsars with main-sequence donors, often referred to as "redbacks," constitute the long-sought link between low-mass X-ray binaries...
