Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they ...

M87, a prominent galaxy in the Virgo cluster, gained fame after the Event Horizon Telescope (EHT) revealed the first image of a black hole in its center. A subsequent study analyzed data from EHT's ...

We performed a commissioning experiment of the hard x-ray and gamma-ray TES microcalorimeter at the J-PARC MLF MUSE muon beam line. The energy resolution, gain stability, and performance of timing ...

The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now ...

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The ...

These facilities can detect X-ray photons as well as high-energy gamma rays. One of the critical datasets analyzed in the study is the spectral energy distribution. “This spectrum reveals how ...

Radiography is the use of X-rays or gamma rays to examine non-uniformly composed material; images are recorded on a sensitized surface, such as photographic film or a digital detector. Medical ...

into the shaft. A strip of industrial X-ray film wound around the engine is bombarded by the gamma rays streaming out from the isotope. The result is a detailed X-ray photograph of the hundreds of ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

In 2018, astronomers took the first-ever picture of a black hole, a fascinating and unprecedented glimpse of an event horizon. And as it turns out, the black hole — dubbed M87* and located some ...
