Astronomers have obtained the sharpest-ever X-ray spectrum of an iconic active galaxy, providing the most accurate, precise ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark ...

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 ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...
