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

open access: yesAstronomy & 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-

Stellar flare detection in XMM-Newton with gradient-boosted trees

open access: yesAstronomy & Astrophysics
Context. The EXTraS project, based on data collected with the XMM-Newton observatory, provides us with a vast amount of light curves for X-ray sources. For each light curve, EXTraS also provides us with a set of features.

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

open access: yesPhysical 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.

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

open access: yesEuropean 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 ...
