X-ray-Induced Heating in the Vicinity of the X-ray Interaction Point

Applied Sciences, 2023
When X-rays pass through a material, radiation damage occurs, and heat is generated at the X-ray interaction point, which can then be transferred around the X-ray irradiation site. This X-ray-induced heat transfer can affect the temperature of the sample

Sources of X-rays from galaxies [PDF]

, 2011
Galactic X-ray emission is a manifestation of various high-energy phenomena and processes. The brightest X-ray sources are typically accretion-powered objects: active galactic nuclei and low- or high-mass X-ray binaries.

Single shot diffraction of picosecond 8.7-keV x-ray pulses

Physical Review Special Topics. Accelerators and Beams, 2012
We demonstrate multiphoton, single shot diffraction images of x rays produced by inverse Compton scattering a high-power CO_{2} laser from a relativistic electron beam, creating a pulse of 8.7 keV x rays.

Recasting the nature of INTEGRAL hard X-ray transients previously classified as active galactic nuclei

Astronomy & Astrophysics
We present new broad-band X-ray results aimed at the identification and characterization of four poorly studied hard X-ray transients discovered by INTEGRAL: IGR J16426+6536, IGR J09446−2636, IGR J21268+6203, and IGR J02447+7046. The key properties and X-

X-ray Observations at Gaisberg Tower

Atmosphere, 2018
We report the occurrence of X-rays at ground level due to cloud-to-ground flashes of upward-initiated lightning from Gaisberg Tower, in Austria, which is located at an altitude of 1300 m.

Pulmonary abnormality screening on chest x-rays from different machine specifications: a generalized AI-based image manipulation pipeline

European Radiology Experimental, 2023
Background Chest x-ray is commonly used for pulmonary abnormality screening. However, since the image characteristics of x-rays highly depend on the machine specifications, an artificial intelligence (AI) model developed for specific equipment usually ...

Observation of Histone H2AX Phosphorylation by Radiation-Induced Bystander Response Using Titanium Characteristic X-ray Microbeam

Biology, 2023
Radiation-induced bystander response (RIBR) is a response induced in non-irradiated cells that receive bystander signals from directly irradiated cells. X-ray microbeams are useful tools for elucidating the mechanisms underlying RIBR. However, previous X-

Efficient concentration of high-energy x-rays for diffraction-limited imaging resolution

, 2017
Newly available x-ray nanobeams in synchrotron radiation facilities open new research avenues in the nanosciences. However, a significant challenge is to efficiently concentrate, particularly for high-energy x-rays, a large photon flux into a very small ...

The Reflection of X-Rays by Crystals

Nature, 1913
IT is interesting to find that an X-ray bulb having a rhodium antikathode gives off a strong, sharply defined (and therefore very homogeneous) beam which is reflected from the (100) face of rock-salt at a glancing angle of 6.2°.

The very faint X-ray transient Swift J174610–290018 at the Galactic center

Astronomy & Astrophysics
Context. Very faint X-ray transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (LX ≲ 1036 erg s−1) much lower than those of typical X-ray transients.
