Gravitational waves from remnants of ultraluminous X-ray sources Ultraluminous X-ray sources (ULXs) with X-ray luminosities larger than the Eddington luminosity of stellar-mass objects may be powered by intermediate-mass... H Clovis,PZ Simon - 《Monthly Notices of the Royal Astronomical Society ...
The Diffuse Emission and a Variable Ultraluminous X‐Ray Point Source in the Elliptical Galaxy NGC 3379 A Chandra observation of the intermediate-luminosity (MB = -20) elliptical galaxy NGC 3379 resolves 75% of the X-ray emission within the central 5?kpc into... LP David,C Jones,W Forman...
The spin evolution of neutron stars and strange-quark stars in low-mass x-ray binary systems (LMXB), driven by accretion and radiating gravitational waves via ther-mode instability, is investigated. We suggest that unstable strange stars can become persistent sources of gravitational waves....
Gravitational waves from the binary black hole (BH) merger GW150914 may enlighten our understanding of ultra-luminous X-ray sources (ULXs), as BHs>30Msun can reach luminosities>4x10^39 erg s^-1 without exceeding their Eddington limit. It is then important to study variations of evolutionary ...
Gamma-Ray Sources In subject area: Physics and Astronomy Gamma-ray sources refer to regions in space emitting high-energy gamma radiation, often discovered through satellite missions. Some of these sources remain unidentified and can be categorized based on their location, spectral properties, and ass...

Extreme focusing of hard X-ray free-electron laser pulses enables 7 nm focus width and 1022 W cm−2 intensity Researchers focused hard X-rays from a free-electron laser down to transverse dimensions of ~7 nm × 7 nm, enabling a two-order increase in intensity of photons and ...
Climate change interacts with the sources and cycling of contaminants, such as radionuclides, in the environment. In this review, we discuss the implications of climate change impacts on existing and potential future sources of radionuclides associated w
Coolidge X-ray Tube There are three basic requirements for the production of X-rays. They are (i) Electron source. (ii) Arrangement to accelerate electrons. (iii) A metal target of suitable material of high atomic mass and high melting point on which high-speed electrons strike. ...
In many pattern forming systems that exhibit traveling waves, sources and sinks occur which separate patches of oppositely traveling waves. We show that simple qualitative features of their dynamics can be compared to predictions from coupled amplitude equations. In heated wire convection experiments, we...
