X-ray reflection in a sample of X-ray bright Ultraluminous X-ray sources [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We apply a reflection-based model to the best available XMM-Newton spectra of X-ray bright UltraLuminous X-ray (ULX) sources (NGC 1313 X-1, NGC 1313 X-2, M 81 X-6, Holmberg IX X-1, NGC 5408 X-1 and Holmberg II X-1).

An X-ray polarimeter for hard X-ray optics [PDF]
SPIE Proceedings, 2006 Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

X-ray sources as tracers of the large-scale structure in the Universe [PDF]
, 2000 We review the current status of studies of large-scale structure in the X-ray Universe. After motivating the use X-rays for cosmological purposes, we discuss the various approaches used on different angular scales including X-ray background multipoles, cross-correlations of the X-ray background with galaxy catalogues, clustering of X-ray selected ...

Disk-Jet Connection in Cygnus X-3 [PDF]
, 2001 We present the results of a detailed correlation study between the soft X-ray, hard X-ray, and radio emission (obtained from RXTE ASM, BATSE, and GBI observations, respectively) of the bright radio emitting Galactic X-ray binary Cygnus X-3. We detect a very strong positive correlation between the soft X-ray and radio emission during the low-hard and ...

Catalogue of high-mass X-ray binaries in the Galaxy ($4^{th}$ edition) [PDF]
Astron.Astrophys.455:1165,2006, 2007 We present a new edition of the catalogue of high-mass X-ray binaries in the Galaxy. The catalogue contains source name(s), coordinates, finding chart, X-ray luminosity, system parameters, and stellar parameters of the components and other characteristic properties of 114 high-mass X-ray binaries, together with a comprehensive selection of the relevant

Probing the X-ray Variability of X-ray Binaries [PDF]
Symposium - International Astronomical Union, 2002 Kilohertz quasi-periodic oscillations (kHz QPOs) has been regarded as representing the Keplerian frequency at the inner disk edge in the neutron star X-ray binaries. The so-called ``parallel tracks'' on the plot of the kHz QPO frequency vs. X-ray flux in

Nature Communications, 2023 Visualizing surface-supported and buried planar mesoscale structures, such as nanoelectronics, ultrathin-film quantum dots, photovoltaics, and heterogeneous catalysts, often requires high-resolution X-ray imaging and scattering.

Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses
Nature Communications, 2021 Cavitation bubbles show many nonlinear characteristics of liquid and gas phase. Here the authors demonstrate coherent diffractive imaging of cavitation bubble using infrared pump and XFEL probe and discuss the formation and evolution of the bubbles.

Superconducting undulator activities at the European X-ray Free-Electron Laser Facility
Frontiers in Physics, 2023 For more than 5 years, superconducting undulators (SCUs) have been successfully delivering X-rays in storage rings. The European X-Ray Free-Electron Laser Facility (XFEL) plans to demonstrate the operation of SCUs in X-ray free-electron lasers (FELs ...
