Dr Daniela Dorner (Universität Würzburg)10/11/2016, 09:25Current detectorsBoth FACT and HAWC are monitoring at TeV energies. While HAWC is covering two thirds of the sky every day, FACT is monitoring a small sample of sources in pointed-mode with a better sensitivity. Thanks to its camera with solid-state photosensors, FACT features an excellent detector performance and stability, which is ideal for monitoring. As the sensors do not degrade when exposed to...Go to contribution page

John Pretz (Penn State)10/11/2016, 09:50Current detectorsHAWC is performing well, achieving unprecedented all-sky sensitivity above 1 TeV. The HAWC sensitivity is driven by the best photon/hadron discrimination and angular resolution ever achieved for a wide-field ground array. I will discuss the HAWC performance, focusing on the HAWC observations of the Crab Nebula, highlighting opportunities for improvement in a future Southern observatory.Go to contribution page

While the former technique presents a better energy and angular resolution, and has a lower energy threshold, the latter gains significantly in duty cycle and survey area.
