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…
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…
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…
Neutron Star Heating in Dark Matter Models for Muon g-2 with Scalar Lepton Partners up to the TeV Scale
Jan Tristram Acuña, Patrick Stengel, Piero Ullio
We investigate the kinetic heating of neutron stars due to dark matter scattering in minimal models with scalar lepton partners mediating interactions which can account for the ano…
A Minimal Dark Matter Model for Muon g-2 with Scalar Lepton Partners up to the TeV Scale
Jan Tristram Acuña, Patrick Stengel, Piero Ullio
The E989 experiment at the Fermi National Laboratory reported a 4.2 discrepancy between the measured magnetic dipole moment of the muon, and its prediction in the Standard Model…
Phenomenological consequences of an interacting multicomponent dark sector
Jan Tristram Acuña, Marco Fabbrichesi, Piero Ullio
We consider a dark sector model containing stable fermions charged under an unbroken gauge interaction, with a massless dark photon as force carrier, and interacting with or…
Dynamics of a planar thin shell at a Taub-FRW junction
Jan Tristram Acuña, Jose Perico Esguerra
We address the problem of stitching together the vacuum, static, planar-symmetric Taub spacetime and the flat Friedmann-Robertson-Walker cosmology using the Israel thin-shell forma…
