The Sun has long been expected to be a steady gamma-ray and neutrino (>GeV) source due to constant bombardment by cosmic rays. I will discuss recent progress in studies of these solar atmospheric gamma rays with the Fermi Space Gamma-ray Telescope, and the prospects of the detecting the Sun with high-energy neutrinos. Surprisingly, the gamma-ray flux was found to be higher than the previous...

The HAWC Collaboration has discovered a γ-ray emission extended about 2 degrees around the Geminga and Monogem pulsar wind nebulae (PWNe) at γ-ray energies Eγ>5 TeV. We analyze, for the first time, almost 10 years of γ-ray data obtained with the Fermi Large Area Telescope at Eγ> 8 GeV in the direction of Geminga and Monogem. Since these two pulsars are close the Galactic plane we run our...

The Gravitational wave high-energy Electromagnetic Counterparts All-sky Monitor (GECAM) project is the planned China’s space telescopes launched in 2020 for searching gamma-rays from gravitational wave events such as double neutron stars merging. GECAM features instantaneous full-sky monitor with two micro-satellites, which can be achieved with relatively short time and small cost based on...

The Tibet air shower (AS) array and underground water-Cherenkov-type muon detector (MD) array have been successfully operated since 2014, at an altitude of 4,300m in Tibet, China. The gamma-ray energy and arrival direction are determined by the Tibet AS array, while the MD array enable us to suppress more than 99.9% of background cosmic rays above 100 TeV, by means of counting number of muons...

The ALPACA experiment is a new international project between Bolivia and Japan. It is going to consist of an 83,000 m^2 surface air shower array and a 5,400 m^2 underground water Cherenkov muon detector array in a current design, and be located at Chacaltaya Plateau at an altitude of 4,740 m. It has the advantages of wide field of view about 2 sr and high duty cycle.
The main target of...
