Reassessing the SIGW Interpretation of PTA Signal: The Role of Third-Order Gravitational Waves and Implications for the PBH Overproduction
Zhi-Chao Zhao, Sai Wang, Qing-Hua Zhu +1
In light of recent interpretations attributing pulsar timing array (PTA) signal to second-order gravitational waves induced by linear cosmological curvature perturbations in the ea…
21 cm forest one-dimensional power spectrum as an indirect probe of dark matter particles and primordial black holes
Meng-Lin Zhao, Yue Shao, Sai Wang +1
Understanding the nature of dark matter (DM) particles remains a pivotal challenge in modern cosmology. Current cosmological research on these phenomena primarily utilizes cosmic m…
All-sky search for individual Primordial Black Hole bursts with LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +311
Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…
Prospective sensitivity of CTAO on detection of evaporating primordial black holes
Chen Yang, Jun-Da Pan, Xin Zhang
As the lifetime of a black hole decreases, the energy of the Hawking radiation it emits increases, ultimately culminating in its disappearance through a powerful burst of gamma ray…
Prospects for probing dark matter particles and primordial black holes with the Hongmeng mission using the 21 cm global spectrum at cosmic dawn
Meng-Lin Zhao, Sai Wang, Xin Zhang
Probing dark matter particles and primordial black holes remains a pivotal challenge in modern cosmology. Exotic energy injections from dark matter annihilation, decay, and PBH Haw…
Constraining primordial black hole abundance with Insight-HXMT
Chen Yang, Jun-Da Pan, Xin Zhang
Primordial black holes (PBHs) are a major candidate for dark matter and they have been extensively constrained across most mass ranges. However, PBHs in the mass range of …
Analytical modeling of the one-dimensional power spectrum of 21-cm forest based on a halo model method
Yue Shao, Tian-Yang Sun, Meng-Lin Zhao +1
The 21-cm forest, composed of spectral absorption features from high-redshift background radio sources, provides a unique probe for studying small-scale structures during the epoch…
Search for the Hawking radiation of primordial black holes: prospective sensitivity of LHAASO
Chen Yang, Sai Wang, Meng-Lin Zhao +1
Primordial black holes (PBHs), more generally, BHs, undergo evaporation and, in principle, will end their lives in bursts of very high-energy gamma rays. The notable aspect of the…
