Among the most fascinating phenomena are gamma rays, the most energetic form of electromagnetic radiation. Recently, ...

Gamma-ray bursts, the most powerful kinds of explosions known in the cosmos, may help provide a piece of the puzzle when it ...

A team of astronomers used three instruments from the Keck Observatory to study WR 104, a stellar system nicknamed the 'death ...

ABSTRACT We present a review of the current status of very high energy γ‐ray astronomy. The development of the atmospheric Cerenkov imaging technique for ground‐based γ‐ray astronomy has led to a ...

The earth's atmosphere blocks most gamma rays from space, so gamma-ray astronomy was not possible until astronomers put gamma-ray detecting telescopes into space. Astronomers were at first ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have ... "This is such a great example of how with astronomy we often begin a study and the ...

New research led by W. M. Keck Observatory Instrument Scientist and astronomer Grant Hill has confirmed what scientists have long suspected—WR 104 comprises two massive stars: a Wolf-Rayet star and an ...

I have published as first author and refereed for every major journal in astronomy and astrophysics. My current research interests include trying to limit attributes of our universe with distant gamma ...

EP also presents substantial opportunities in multi-messenger astronomy, with the capability ... as well as ultra-high-energy gamma rays, and cosmic ray origins. These observations will provide ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
