TeV Gamma-ray Astrophysics

Friday September 28, 2018
3:30 pm


 Presenter:  John Matthews, Physics and Astronomy, UNM
 Series:  Physics and Astronomy Colloquium
 Abstract:  By observing the universe at different wavelengths (photon energies) we find new classes of sources and/or we better understand the physics of known sources, for example: optical wavelengths are well matched to thermal (Black Body = thermal) sources such as stars radio wavelengths are sensitive to cold thermal sources (eg molecular clouds) and to non-thermal sources eg synchrotron radiation, with discovery of: radio galaxies and quasars, pulsars and binary pulsars, ...

Detection of astrophysical sources at TeV energies took decades with the first observation in 1989 of the Crab nebula. In recent years so-called multi-wavelength and multi-messenger observations are critical to study the physics of these (TeV) sources.

So: what does the Universe look like at TeV energies? What type of sources dominate the TeV sky? And what has been learned?
