High-energy experiments: results and connections with Gravitational Waves
Talk
The High-Altitude Water Cherenkov Observatory (HAWC) is a TeV gamma-ray detector located at an altitude of 4,100 meters on the slope of the Sierra Negra volcano in Puebla, Mexico.
Inaugurated in March 2015, HAWC observes 65% of the sky every day with more than 90% duty cycle and an excellent angular resolution. HAWC plays an important role as a survey instrument for multi-wavelength studies,...

The High Energy Stereoscopic System (H.E.S.S.) is an array of Imaging Atmospheric Cherenkov Telescopes (IACTs) located in the Khomas Highland of Namibia. The array initially consisted of four 12 m telescopes, operating as a single stereoscopic system. A decade of H.E.S.S. observations yielded a vast array of discoveries which now form the heritage of the very-high-energy (VHE) gamma-ray...

MAGIC is an instrument composed of a pair of telescopes for gamma-ray and cosmic-ray astrophysics in the TeV range. It is operating for more than a decade now, and is one of the current best performing instruments in this field, specifically at low energies, where it achieves the largest sensitivity among current installations of this kind. MAGIC pursues a strong program in galactic and...

VERITAS is an array of four 12-m imaging atmospheric-Cherenkov telescopes, sensitive to very-high-energy (VHE; >100 GeV) gamma rays. Ground-based VHE instruments like VERITAS provide powerful means to probe into astrophysics problems including the particle acceleration and radiative processes in both Galactic and extragalactic sources, cosmological problems such as the history of galaxy...

The Large Array Telescope for Tracking Energetic Sources ( LATTES ) is a
novel hybrid detector concept for the measurement of Extensive Air Showers (EAS) generated by Very High Energy Gamma rays. The aim of the detector is to have a good sensitivity at low energies (~100 GeV) extending into the TeV region, operating day and night with a wide field of view.
The experiment is planned to be...

In early 2016 the LIGO and Virgo collaborations reported the breakthrough observation of the first gravitational-wave transient with the twin detectors of Advanced LIGO in September 2015 (event GW150914), followed three months later by the detection of GW151226. Both events are produced by the coalescence of black holes. Although no electromagnetic emission is generally expected from such...

A number of groups are developing pair-conversion detector technologies alternative to the tungsten-converter / thin-sensitive-layer stacks of the COS-B / EGRET / Fermi-LAT series, to improve the single-photon angular resolution.
Presently observers are almost blind in the 1-100 MeV energy range, mainly due to the degradation of the angular resolution of e+e- pair telescopes at low energies:...

Gamma ray astronomy suffers from a sensitivity gap between 0.1 and 100MeV.
The lower end can be covered by improved Compton telescopes, while the higher end needs to use photon conversion to electron-positron pairs.
With high angular resolution for the electrons, it will also be possible to probe the linear polarisation of the photons.
There is a fierce competition to build high sensitivity...
