Pathways and impediments towards a detection of the relic neutrino wind

Andrew J. Long, Michiru Uwabo-Niibo, Masahide Yamaguchi

A direct detection of the cosmic neutrino background (CNB) in laboratories on Earth has been called the ``holy grail'' of experimental neutrino physics, but a still more glorious p…

Plasma heating during the chiral plasma instability

Balin Armstrong, Andrew J. Long, Károly Seller +1

The presence of a chiral asymmetry in a relativistic plasma opens a tachyonic instability toward the growth of a helical magnetic field. We study the transfer of energy from the ch…

Nonthermal leptogenesis via cosmological gravitational particle production is tested by inflationary gravitational waves

Tammi Chowdhury, Leah Jenks, Edward W. Kolb +2

We explore the coincidence of scales between cosmic inflation and right-handed neutrinos in seesaw models. We show that inflation models, which will be tested by next-generation CM…

Resonant conversion of axion dark radiation into terahertz electromagnetic radiation in a neutron star magnetosphere

Andrew J. Long, Enrico D. Schiappacasse

In the strong magnetic field of a neutron star's magnetosphere, axions coupled to electromagnetism develop a nonzero probability to convert into photons. Past studies have revealed…

Thermal pressure on ultrarelativistic bubbles from a semiclassical formalism

Andrew J. Long, Jessica Turner

We study a planar bubble wall that is traveling at an ultrarelativistic speed through a thermal plasma. This situation may arise during a first-order electroweak phase transition i…

Neutron star cooling with lepton-flavor-violating axions

Hong-Yi Zhang, Ray Hagimoto, Andrew J. Long

The cores of dense stars are a powerful laboratory for studying feebly coupled particles such as axions. Some of the strongest constraints on axionlike particles and their coupling…
