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 ...

Using high-resolution 1665/1667 MHz OH line and continuum spectrum observational data from the European VLBI Network and the ...

Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars ...

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 ...

Ratiometric fluorescence is a method where the intensities at two or more wavelengths of an emission spectrum or excitation are measured in order to detect changes to a local environment. This is ...

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 ...
