The nature of the X-ray transient MAXI J0556−332 [PDF]

open access: yes, 2012
Phase-resolved spectroscopy of the newly discovered X-ray transient MAXIJ0556-332 has revealed the presence of narrow emission lines in the Bowen region that most likely arise on the surface of the mass donor star in this low-mass X-ray binary.

Compact objects in active galactic nuclei and X-ray binaries [PDF]

open access: yes, 2007
In this thesis I study the inner-most regions of Active Galactic Nuclei (AGN) using the reverberation mapping technique, and neutron star low-mass X-ray binaries in quiescence using X-ray observations. Using the 13-year optical monitoring data for the

Protocols for x-ray transient grating pump/optical probe experiments at x-ray free electron lasers [PDF]

open access: yes
Transient grating spectroscopy is a specialized application of the four-wave-mixing methodology and constitutes a versatile technique for investigating the dynamics of vibrational, magnetic and electronic degrees of freedom of matter in a background-free

Vacuum birefringence and X-ray polarimetry in transient magnetars [PDF]

open access: yes, 2017
Recent optical polarimetry observations of an X-ray dim isolated neutron star, RX J1856.5-3754, showed a first evidence for QED vacuum birefringence induced by a strong magnetic field.

Pinch plasmas as intense X-ray sources for laboratory applications

open access: yes, 2022
S.479-482 : Abb.,Lit.Pinch plasma x-ray sources have been developed for x-ray lithography and x-ray microscopy. The lithography source is compatible with the electron storage ring printing process with respect to spectrum and enables full depth exposures

The very soft X-ray transient H1853 + 60 [PDF]

open access: yes, 1981
The increased sensitivity, sky coverage and spectral range of X-ray observatories have revealed a wide range of transient phenomena. The 'classical' X-ray transients flare rapidly, sometimes increasing by more than an order of magnitude in X-ray flux in ...

INTEGRAL observations of recurrent fast X-ray transient sources

open access: yes, 2005
Fast X-ray Transients (FXTs) are believed to be non-recurrent bright X-ray sources lasting less than a day and occurring at serendipitous positions, they can best detected and discovered by instruments having a sufficiently wide field of view and high ...

On the x-ray outbursts of transient anomalous x-ray pulsars and soft gamma-ray repeaters [PDF]

open access: yes, 2012
We show that the X-ray outburst light curves of four transient anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), namely, XTE J1810–197, SGR 0501+4516, SGR 1627–41, and CXOU J164710.2–455216, can be produced by the fallback disk model ...
