"The gamma-ray burst traveled through intergalactic ... Astronomers have sent x-ray telescopes into orbit to scan the sky, to catch the first x-ray afterglow of a burst as soon as possible.

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

Furthermore, the astronomers analyzed multiwavelength data of 3C 216, finding simultaneous flaring activity in optical, ultraviolet, X-ray and gamma-ray bands between May 1–9, 2023. This ...

These flares are some of the most explosive events in the cosmos, releasing a huge amount of gamma rays in a very short time. If XRT 200515 is an X-ray counterpart to such an event, it would be ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

The Beijing symposium revealed that WXT found its first X-ray transient on Feb. 19, an event associated with a long gamma-ray ...

In this research, we will establish an imaging method to visualize line X-ray gamma-rays from activated materials in general. We will expand this method to the fields of space, medicine, and ...

Mar. 1, 2022 — Continuing X-ray observations by Chandra of the kilonova from the merger of two neutron stars to form a black hole hint at new processes. Initially, a gamma-ray burst and ...
