gamma rays - 2024 ARCADIA - Buzzpoints App

Question

The GRAMS project plans to launch a liquid argon time projection chamber into space to detect these particles in the MeV range, potentially from sources like neutron star mergers and blazars. For 10 points each:

[10h] Name these particles previously detected with Compton telescopes. In time projection chambers, the tracks left by these particles are distinguished by a gap between the interaction vertex and the electromagnetic shower.

ANSWER: gamma rays [prompt on photons by asking “what are they known as in the MeV energy scale?”]

[10m] The VERITAS array in Arizona can detect atmospheric gamma rays by their emission of this phenomenon. This phenomenon is responsible for the characteristic blue glow of a nuclear reactor core.

ANSWER: Cherenkov light [or Cherenkov radiation]

[10e] The Fermi Telescope in low Earth orbit can detect and characterize gamma-ray bursts by observing their pair production into electrons and these antiparticles.

ANSWER: positrons [or e-plus]
