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…
Constraints on ultracompact minihalos from the extragalactic gamma-ray background observation
Xing-Fu Zhang, Ji-Gui Cheng, Ben-Yang Zhu +3
Ultracompact minihalo (UCMH) is a special type of dark matter halo with a very steep density profile which may form in the early universe seeded by an overdense region or a primord…
Effect of axion-like particles on the spectrum of the extragalactic gamma-ray background
Yun-Feng Liang, Xing-Fu Zhang, Ji-Gui Cheng +3
Axion-like particles (ALPs) provide a feasible explanation for the observed lower TeV opacity of the Universe. If the anomaly TeV transparency is caused by ALPs, then the fluxes of…
