Previous research also indicated that Earth looks down the axis of this system, known as Wolf-Rayet 104, raising concerns ...

The discovery, and the newly identified position of the binary companion, mean we no longer have to fret about the Pinwheel ...

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

We could pull a Bruce Willis in Armageddon, maybe. It's a fair game. A nearby gamma-ray burst could kill us all. And they can move at close to the speed of light, so oblivion would strike very ...

What Martí-Devesa and team co-leader Laura Olivera-Nieto from the Max Planck Institute for Nuclear Physics found is a new source of gamma-rays that is consistent with the position of GRS 1915+105 ...

The same result is obtained when studying the pulse-height from the gamma-rays emitted by different substances. There is, in this case, a continuous distribution of pulses from zero to a certain ...

An isotope emits gamma rays that easily pass through the body to a detector outside the body, for example a ‘gamma camera’. In this way, the radioactive isotope can be followed as it flows ...

The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...
