Insight-HXMT observations of jet-like corona in a black hole X-ray binary MAXI J1820+070

open access: yesNature Communications, 2021
Evolution of accretion disk and corona during outbursts in black hole binary systems is still unclear. Here, the authors show spectral analysis of MAXI J1820+070 and propose a scenario of a dynamical corona to explain the evolution of the reflection ...

High energy neutrino astrophysics [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2005
Astroparticle physics is a field rich of perspectives in investigating the ultra-high energy region which will never be accessible to man made machines. Many efforts are underway in order to detect the first cosmic neutrinos, messengers of the unobserved universe.

Soft scattering evaporation of dark matter subhalos by inner galactic gases

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The large gap between a galactic dark matter subhalo’s velocity and its own gravitational binding velocity creates the situation that small subhalos can be evaporated before dark matter thermalize with baryons due to the low binding velocity.

Fermi-LAT Observation of PSR B1259-63 during Its 2021 Periastron Passage

open access: yesUniverse, 2021
PSR B1259-63 is a γ-ray binary system, where the compact object is a pulsar. The system has an orbital period of 1236.7 days and shows peculiar γ-ray flares (in 100 MeV–300 GeV) after its periastron time.
