Warm Inflation with Pseudo-scalar Couplings

Edward Broadberry, Anson Hook, Sagnik Mondal

Inflaton couplings during warm inflation result in the production of a thermal bath. Thermal friction and fluctuations can dominate the standard de Sitter analogues, resulting in a…

Modeling Binary Lenses and Sources with the BAGLE Python Package

T. Dex Bhadra, J. R. Lu, Natasha S. Abrams +4

Gravitational microlensing is a powerful tool that can be used to find and measure the mass of isolated and dark compact objects. In many microlensing events, the lens, the source,…

Charged Loops at the Cosmological Collider with Chemical Potential

Arushi Bodas, Edward Broadberry, Raman Sundrum +1

Cosmological collider physics allows the detection of heavy particles at inflationary scales through their imprints on primordial non-Gaussianities. We study the chemical potential…

The BAGLE Python Package for Bayesian Analysis of Gravitational Lensing Events

J. R. Lu, M. Medford, C. Y. Lam +8

We present the open-source Python package, BAGLE (Bayesian Analysis of Gravitational Lensing Events), which enables modeling and joint fitting of photometric and astrometric data s…

Adiabatic Conversion of ALPs into Dark Photon Dark Matter

Edward Broadberry, Saurav Das, Anson Hook +1

We introduce a mechanism by which a misaligned ALP can be dynamically converted into a dark photon in the presence of a background magnetic field. An abundance of non-relativistic…

Vector Portals at Future Lepton Colliders

Sagar Airen, Edward Broadberry, Gustavo Marques-Tavares +1

We assess the sensitivity of future lepton colliders to weakly coupled vector dark portals (aka `` bosons'') with masses ranging from tens of GeV to a few TeV. Our analysis f…
