Constraining the parameters of heavy dark matter and memory-burdened primordial black holes with DAMPE electron measurements
Tian-Ci Liu, Ben-Yang Zhu, Yun-Feng Liang +2
The DArk Matter Particle Explorer (DAMPE) is a space-based instrument for detecting GeV-TeV cosmic rays and gamma rays. High-energy cosmic rays could be emitted from several dark m…
Constraints on primordial black holes in dSphs using radio observations
Tian-Ci Liu, Xiao-Song Hu, Yun-Feng Liang +3
Primordial black holes (PBHs) are hypothetical objects formed at the early epoch of the universe, which could be a type of dark matter (DM) candidate without the need for new parti…
Constraining dark photon parameters based on the very high energy observations of blazars
Tian-Ci Liu, Ming-Xuan Lu, Xiao-Song Hu
Dark photon is a new gauge boson beyond the Standard Model as a kind of dark matter (DM) candidate. Dark photon dark matter (DPDM) interacts with electromagnetic fields via kinetic…
Constraints on the annihilation of heavy dark matter in dwarf spheroidal galaxies with gamma-ray observations
Xiao-Song Hu, Ben-Yang Zhu, Tian-Ci Liu +1
Electrons and positrons produced in dark matter annihilation can generate secondary emission through synchrotron and IC processes, and such secondary emission provides a possible m…
