have discovered that this ultrafast charge delocalization can be examined using a simpler method—X-ray spectroscopy. They are ...

X-ray spectrum of the Centaurus Galaxy Cluster measured with the XRISM Resolve spectrometer. The spectrometer on the XRISM satellite can tell peaks apart with unparalleled resolution.

EDS works by focusing an electron beam onto the sample, which causes the sample to emit X-rays. Each element emits X-rays at unique energy levels, allowing for the identification and quantification of ...

The process begins with the absorption of X-ray photons by atoms in the material, leading to the ejection of photoelectrons. By analyzing the energy spectrum of these photoelectrons, information about ...

The Helsinki Center for X-ray Spectroscopy is a unique research and education infrastructure serving users from both academia and industry in their leading-edge research, development and innovation.

Ultrafast X-ray spectroscopy enables the exploration of molecular dynamics with unprecedented temporal resolution, element specificity, and site selectivity. These unique properties make it ideal for ...

The study found that the X-ray spectrum of HL Tau is consistently hot and heavily absorbed at all 31 observational epochs spanning 20 years. This is common for typical heavily-absorbed Class I YSOs.
