DOI: 10.1016/j.anucene.2020.107970
Abstract: Abstract Computer tomography (CT) is a useful probe to measure two-phase flow parameters. Because of the dynamic characteristic of the two-phase flow, the high temporal CT is required. A compact CT system, consists of seven… read more here.

DOI: 10.1038/s41598-020-72053-z
Abstract: High-intensity X-ray sources are essential diagnostic tools for science, technology and medicine. Such X-ray sources can be produced in laser-plasma accelerators, where electrons emit short-wavelength radiation due to their betatron oscillations in the plasma wake… read more here.

DOI: 10.1063/1.5015927
Abstract: Laser heated plasmas have provided recently some of the most powerful and energetic nanosecond length laboratory sources of x-ray photons (Ephoton = 1–30 keV). The highest x-ray to laser conversion is currently accessible by using underdense (ne ∼ 0.25 nc)… read more here.

DOI: 10.1093/mnras/sty014
Abstract: We present the discovery and interpretation of ionized nebulae around two ultraluminous X-ray sources in M 51; both sources share the rare property of showing X-ray eclipses by their companion stars, and are therefore prime… read more here.

DOI: 10.1093/mnras/sty2213
Abstract: We study the evolution of binary systems of Ultra-luminous X-ray sources and compute their optical emission assuming accretion onto a black hole via a non standard, advection-dominated slim disc with an outflow. We consider systems… read more here.

DOI: 10.1093/mnras/stz1027
Abstract: We analysed the X-ray power density spectra of five ultraluminous X-ray sources (ULXs) NGC 5408 X-1, NGC 6946 X-1, M 82 X-1, NGC 1313 X-1, and IC 342 X-1 that are the only ULXs that display both flat-topped noise (FTN) and quasi-periodic oscillations (QPOs). We… read more here.

DOI: 10.1093/mnras/stz3036
Abstract: Motivated by the recent discoveries that six Ultraluminous X-ray Sources (ULXs) are powered by highly super-Eddington X-ray pulsars, we searched for additional pulsating ULX (PULX) candidates by identifying sources that exhibit long-term flux variability of… read more here.
