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

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 ...

The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for the ...
