Phenomenology of bubble size distributions in a first-order phase transition
Danny Marfatia, Po-Yan Tseng, Yu-Min Yeh
In a cosmological first-order phase transition (FOPT), the true and false vacuum bubble radius distributions are not expected to be monochromatic, as is usually assumed. Consequent…
Primordial Black Hole signatures from femtolensing and spectral fringe of Gamma Ray Bursts
Chang-Yu Dai, Po-Yan Tseng
Femtolensing of gamma-ray bursts (GRBs) is vastly studied to constrain primordial black holes lighter than solar mass and may close the window for PBH dark matter. In th…
Constraining memory-burdened primordial black holes with graviton-photon conversion and binary mergers
Po-Yan Tseng, Yu-Min Yeh
The memory-burden effect stabilizes the evaporating Primordial Black Holes (PBHs) before its complete decay. This also suppresses the evaporation flux via the entropy factor to the…
Angular momentum of vacuum bubbles in a first-order phase transition
Jan Tristram Acuña, Danny Marfatia, Po-Yan Tseng
The formation of primordial black holes (PBHs) during a first-order phase transition (FOPT) in a dark sector has been of recent interest. A quantity that characterizes a black hole…
Phenomenology of Neutrino-Dark Matter Interaction in DSNB and AGN
Po-Yan Tseng, Yu-Min Yeh
We investigate a neutrino-scalar dark matter (DM) interaction encountering distinctive neutrino sources, namely Diffuse Supernova Neutrino Background (DSNB) and Active Galac…
Constraints on extended axion structures from the lensing of fast radio bursts
Jan Tristram Acuña, Kuan-Yen Chou, Po-Yan Tseng
Axions are hypothetical pseudoscalar particles that have been regarded as promising dark matter (DM) candidates. On the other hand, extended compact objects such as axion stars, wh…
