X-ray spectra obtained with EPIC on XMM-Newton reveal very high-temperature plasma (kT > 5 keV) in both objects, but no large flares. Such hard X-ray emission is not anticipated from accretion shocks and is a signature of magnetic processes. We place these new results into the context ...

近十年来,人们将X射线共振弹性散射(resonant elastic X-ray scattering,REXS)应用在量子材料研究中,并取得重要的进展,例如G. Ghiringhelli等人利用REXS技术在2012年最早观察到铜氧化物(Y,Nd)Ba2Cu3O6+x中非公度(即波长与晶体周期之比为无理数)的电荷密度波及其与超导关联的实验证据[62],从而掀起了高温超导机理...

众所周知,X射线光谱有很多分类,例如X射线吸收光谱(X-ray Absorption Spectroscopy, XAS),X 射线发射光谱(X-ray Emission Spectroscopy,XES)等等。对于不同的样品,不同的反应过程和生物化学结构,其动态过程的时间尺度是不一样的。所以,选择合适的探测手段,对我们研究不同的动力学过程至关重要。同时,恰当的探测方式...

This emission, relativistic high-order harmonic generation (RHHG), has been extensively studied with an...
Using NASA's Chandra spacecraft, European astronomers have detected a diffuse X-ray emission around an ultraluminous X-ray pulsar in the galaxy NGC 5907. The newly detected emission could be an expanding nebula powered by the wind of the pulsar. The find

Flare star, any star that varies in brightness, sometimes by more than one magnitude, within a few minutes. The cause is thought to be the eruption of flares much larger than, but otherwise similar to, those observed on the Sun. Flare stars are sometimes
