Description

TeV gamma-ray astronomy is led by two main ground-based facilities: imaging atmospheric Cherenkov telescopes, and water Cherenkov detectors. They are very different in terms of concept, operation strategy, and data analysis, but they observe the sky in a similar energy range. During this seminar, I will introduce you to these two different detection techniques via two instruments: H.E.S.S. which is an array of five Cherenkov telescopes, and HAWC, a wide field of view gamma-ray observatory using the water Cherenkov technique. Despite their intrinsic differences, I will emphasise their complementarity by showing a comparison of the galactic plane as observed by HAWC and by HESS. The detailed analysis of a region of gamma-ray emission at galactic longitude b~53°, where HAWC detected the new TeV gamma-ray source 3HWC J1928+178, will be presented.

 

 

The material presented during this seminar must be kept internal to NARIT and not be shown publicly as it contains preliminary, early and unpublished results.
