Quintessential dark energy crossing the phantom divide
Ruiqi Chen, James M. Cline, Varun Muralidharan +1
Motivated by recent results from the DESI collaboration, we explore two classes of quintessence models that can give rise to crossing of the dark energy equation of state through t…
Simple quintessence models in light of DESI-BAO observations
James M. Cline, Varun Muralidharan
Recent analyses from the DESI collaboration suggest that the dark energy density of the Universe may be decreasing with time, slowing the acceleration of the scale factor . Typi…
Can Baby Universe Absorption Explain Dark Energy?
Varun Muralidharan, James M. Cline
It has been proposed that the accelerated expansion of the universe can be explained by the merging of our universe with baby universes, resulting in dark energy with a phantom-lik…
New bounds on light millicharged particles from the tip of the red-giant branch
Audrey Fung, Saniya Heeba, Qinrui Liu +3
Stellar energy loss is a sensitive probe of light, weakly coupled dark sectors, including ones containing millicharged particles (MCPs). The emission of MCPs can affect stellar evo…
