Dark Energy Bubble as Dynamical Dark Energy: Properties and CMB Constraints
Batia Friedman-Shaw, Matthew C. Johnson, Katherine J. Mack
Recent DESI results are in tension with the constant dark energy density predicted by the CDM model. If dark energy is associated with the vacuum energy of a scalar field in a m…

Doppler bias: impact of peculiar velocities on color selection and the large scale structure of galaxy surveys
Batia Friedman-Shaw, Alex Krolewski, Matteo Foglieni +1
Lightcone selection effects on cosmic observables must be precisely accounted for in the next generation of surveys, including the Dark Energy Spectroscopic Instrument (DESI) surve…

Holographic scattering and non-minimal RT surfaces
Jacqueline Caminiti, Batia Friedman-Shaw, Alex May +2
In the AdS/CFT correspondence, the causal structure of the bulk AdS spacetime is tied to entanglement in the dual CFT. This relationship is captured by the connected wedge theorem,…
