DOI: 10.1007/s10509-017-3201-1
Abstract: In this paper, we first discuss a series of important but puzzling physical mechanisms concerning the energy source, various kinds of core collapsed supernovae explosion mechanisms during central gravitational collapse in astrophysics. We also discuss… read more here.

DOI: 10.1038/s41550-017-0139
Abstract: Ultrarelativistic photons and neutrinos from gamma-ray bursts offer a testbed for quantum gravity effects that would lead to an energy dependence of the travel times. A statistical analysis of astrophysical data shows that this behaviour… read more here.

DOI: 10.1038/s41550-020-01276-x
Abstract: Fast radio bursts (FRBs) are short (millisecond) radio pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnetized neutron stars (magnetars) have been considered as the sources… read more here.

DOI: 10.1038/s41550-021-01302-6
Abstract: Fast radio bursts (FRBs) are short pulses observed in the radio band from cosmological distances1. One class of models invokes soft gamma-ray repeaters (SGRs), or magnetars, as the sources of FRBs2. Some radio pulses have… read more here.

DOI: 10.1103/physrevd.99.103012
Abstract: If the weak equivalence principle (WEP) is broken, the measured values of the parametrized post-Newtonian parameter. from photons with left- and right-handed circular polarizations should differ slightly, leading to the arrival-time difference of these two… read more here.
