Astronomers have analyzed new and archival multiwavelength observations of the active galaxy NGC 5273. As a result, they detected so-called "changing-look" events in the active galactic nucleus of this galaxy. The finding ...
Astronomers from Taiwan have performed X-ray observations of the galaxy NGC 1559 using NASA's Chandra spacecraft. They detected eight new ultraluminous X-ray sources in this galaxy. The finding is reported in a paper published ...
To create X-rays—short wave radiation—scientists at TU Vienna start out with very long wavelengths—infrared laser. Long wavelength laser pulses rip atoms out of metal and accelerate them, which leads to emission of ...
