Figure 1: The XMM-Newton RGS spectra of EXO0748-676 for 28 type I X-ray bursts. We inspected the spectra obtained by the two RGS spectrometers separately and found that all the features appear in both ...

Insight-HXMT’s discovery of the fundamental electron cyclotron absorption line near 146 keV for the first Galactic ultraluminous X-ray pulsar Swift J 0243.6+6124. Neutron stars have the strongest ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...

The relative amounts of apparent photosynthesis in two portions of the spectrum, one usually in the yellow, were determined for white pine trees grown in red or in blue-violet light. There were rather ...
