White Dwarf Bounds on CHAMPs
Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran
White dwarfs (WD) effectively act as high-gain amplifiers for relatively small energy deposits within their volume via their supernova instability. In this paper, we consider the w…
Minimal Warm Inflation
Kim V. Berghaus, Peter W. Graham, David E. Kaplan
Slow-roll inflation is a successful paradigm. However we find that even a small coupling of the inflaton to other light fields can dramatically alter the dynamics and predictions o…
Supernova signals of light dark matter
William DeRocco, Peter W. Graham, Daniel Kasen +2
Dark matter direct detection experiments have poor sensitivity to a galactic population of dark matter with mass below the GeV scale. However, such dark matter can be produced copi…
Relaxation of the Cosmological Constant
Peter W. Graham, David E. Kaplan, Surjeet Rajendran
We present a model that naturally tunes a large positive cosmological constant to a small cosmological constant. A slowly rolling scalar field decreases the cosmological constant t…
Observable signatures of dark photons from supernovae
William DeRocco, Peter W. Graham, Daniel Kasen +2
A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive…
