Searching for ultralight bosons with Josephson junction interferometry
Djuna Croon, Tanmay Kumar Poddar
Ultralight bosons sourced by macroscopic objects can generate long-range spin-independent and spin-dependent potentials that are accessible to precision interferometry. Such potent…
Dark matter silences Cepheids in the Galactic Center
Djuna Croon, Tim Linden, Jeremy Sakstein
Upcoming near-infrared facilities (e.g. JWST/NIRCam, ELT/MICADO) will dramatically increase the detectability of galactic center Cepheids despite extreme extinction at optical wave…
Interpreting the 95 GeV resonance in the Two Higgs Doublet Model: Implications for the Electroweak Phase Transition
Ansh Bhatnagar, Djuna Croon, Philipp Schicho
We investigate if the recent mass resonance excesses seen around 95 GeV at the Large Hadron Collider (LHC) can be reconciled with a first-order electroweak phase transition. Perfor…
Gravitational Waves from Phase Transitions
Djuna Croon, David J. Weir
We summarise the physics of first-order phase transitions in the early universe, and the possible ways in which they might come about. We then focus on gravitational waves, emphasi…
Hot Leptogenesis
Michael J. Baker, Ansh Bhatnagar, Djuna Croon +1
We investigate a class of leptogenesis scenarios in which the sector containing the lightest right-handed neutrino establishes kinetic equilibrium at a temperature $T_{N_1} > T_\te…
Cosmology and Astrophysics of CP-Violating Axions
Omar F. Ramadan, Jeremy Sakstein, Djuna Croon
We study the cosmology and astrophysics of axion-like particles (ALPs) with CP-violating Yukawa couplings to nucleons. At finite nucleon density, the ALP's dynamics is governed by…
