Efficient picosecond x-ray pulse generation from plasmas in the radiation dominated regime
(Optical Society of America, 2017-10)
The efficient conversion of optical laser light into bright ultrafast x-ray pulses in laser created plasmas is of high interest for dense plasma physics studies, material science, and other fields. However, the rapid ...
The gamma-ray sky seen at X-ray energies. I. Searching for the connection between X-ray and gamma-rays in Fermi BL Lac objects
(EDP Sciences, 2019-10)
Context. BL Lac objects are an extreme type of active galactic nuclei (AGNs) that belong to the largest population of γ-ray sources: blazars. This class of AGNs shows a double-bumped spectral energy distribution that is ...

The γ -ray sky seen at X-ray energies: II. The swift hunt of fermi BL lac objects among unidentified γ -ray sources
(EDP Sciences, 2020-06)
Context. Nearly 50% of all sources detected by the Fermi Large Area Telescope are classified as blazars or blazar candidates, one of the most elusive classes of active galaxies. Additional blazars can also be hidden within ...
XDS: a flexible beamline for X-ray diffraction and spectroscopy at the Brazilian synchrotron
(Wiley Blackwell Publishing, Inc, 2016-11)
The majority of the beamlines at the Brazilian Synchrotron Light Source Laboratory (LNLS) use radiation produced in the storage-ring bending magnets and are therefore currently limited in the flux that can be used in the ...
Background radiation in inelastic X-ray scattering and X-ray emission spectroscopy. A study for Johann-type spectrometers
(Elsevier Science, 2018-06-21)
A study of the background radiation in inelastic X-ray scattering (IXS) and X-ray emission spectroscopy (XES) based on an analytical model is presented. The calculation model considers spurious radiation originated from ...
Scrutinize of X-rays Compton Scattering Through the Classical Hartemann-Kerman Model and Dalitz-like Plots Technique
(Institute of Electrical and Electronics EngineersPE, 2022-03-15)
In this paper the identification of harmonics of high order due to the interaction of a GeV electron and a super-intense laser pulse with linear polarization is done. For this it is used the technique known as the Dalitz’s ...
An IAEA Multi-technique X-ray Spectrometry End-station at Elettra Sincrotrone Trieste: Benchmarking Results and Interdisciplinary Applications
(Wiley Blackwell Publishing, Inc, 2018-01)
The International Atomic Energy Agency (IAEA) jointly with the Elettra Sincrotrone Trieste (EST) operates a multipurpose X-ray spectrometry endstation at the X-ray Fluorescence beamline (10.1L). The facility has been ...
The intriguing nature of the high-energy gamma ray source XSS J12270-4859
(EDP Sciences, 2010-06)
The nature of the hard X-ray source XSS J12270-4859 is still unclear. It was claimed to be a possible magnetic Cataclysmic Variable of the Intermediate Polar type from its optical spectrum and a possible 860 s X-ray ...
Green Peas in X-Rays
(IOP Publishing, 2019-08)
Green Peas represent a population of compact, highly star-forming dwarf galaxies at redshifts z ∼ 0.2-0.3 that have recently been found to show signatures of ultraviolet ionizing radiation leakage. They are being considered ...
