High-resolution X-ray diffraction beamline at the LNLS for the study of charge, orbital and magnetic structures
(Blackwell MunksgaardCopenhagenDinamarca, 2003)
The Calan-Yale Deep Extragalactic Research (CYDER) survey: Optical properties and deep spectroscopy of serendipitous X-ray sources
(IOP PUBLISHING, 2005-03-01)
We present the first results from the Calan-Yale Deep Extragalactic Research (CYDER) survey. The main goal of this survey is to study serendipitous X-ray sources detected by Chandra in an intermediate flux range (10(-15) ...
Influence of annealing on X-ray diffraction of natural alexandrite
(J C P D S-int Centre Diffraction Data, 2014)
Crystal structure, optical and magnetic properties of perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles: An experimental and first-principles studies
(Elsevier Ltd, 2019)
The perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles were synthesized by a facile sol-gel technique. The structure, electronic structure, surface morphology, optical and magnetic properties of GdMn0.7Ni0.3O3 nanoparticles ...
Symbiotic stars in X-rays
(Edp Sciences S A, 2012-11-27)
Until recently, symbiotic binary systems in which a white dwarf accretes from a red giant were thought to be mainly a soft X-ray population. Here we describe the detection with the X-ray Telescope (XRT) on the Swift satellite ...
All-optical switching device for infrared based on PbTe quantum dots
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
Multilayers of PbTe quantum dots embedded in SiO2 were fabricated by alternate use of Pulsed Laser Deposition (PLD) and Plasma Enhanced Chemical Vapor Deposition (PECVD) techniques. The morphological properties of the ...
High-redshift x-ray–selected quasars: CXOCY J125304.0_090737 joins the club
We present a new X-ray–selected high-redshift quasar CXOCY J125304.0 090737 at z = 4.179, discovered by the Cala´n-Yale Deep Extragalactic Research (CYDER) Survey. This quasar is the fifth X-ray– selected high-redshift ...
Fabrication of dielectric hollow submicrometric pipes
(Amer Inst PhysicsMelvilleEUA, 2000)
Efficient picosecond x-ray pulse generation from plasmas in the radiation dominated regime
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 ...
