Searching for Dark Photon Tridents Through Primordial Black Hole Signatures
Kingman Cheung, C. J. Ouseph, Po-Yan Tseng +1
The detection of gamma-ray signals from primordial black holes (PBHs) could provide compelling evidence for their role as a dark matter candidate, particularly through the observat…
NANOGrav Signal and PBH from the Modified Higgs Inflation
Kingman Cheung, C. J. Ouseph, Po-Yan Tseng
This study investigates the classical Higgs inflation model with a modified Higgs potential featuring a dip. We examine the implications of this modification on the generation of c…
Type Ia Supernovae Induced by Primordial Black Holes from Dark First-Order Phase Transition
Pin-Jung Chen, Po-Yan Tseng
A primordial black hole (PBH) with mass is currently beyond the sensitivity of both microlensing and black hole (BH) evaporation m…
Probing primordial black holes from a first order phase transition through pulsar timing and gravitational wave signals
Jan Tristram Acuña, Po-Yan Tseng
In this work, we assess the sensitivity reach of pulsar timing array (PTA) measurements to probe pointlike primordial black holes (PBHs), with an extended mass distribution, which…
Boosted dark matter from primordial black holes produced in a first-order phase transition
Danny Marfatia, Po-Yan Tseng
During a cosmological first-order phase transition in a dark sector, fermion dark matter particles can form macroscopic Fermi balls that collapse to primordial black holes (PBH…
511 keV galactic line from first-order phase transitions and primordial black holes
Po-Yan Tseng, Yu-Min Yeh
Hawking evaporation of primordial black hole (PBH), with mass and fractional abundance $0.01 \lesssim f_{\…
