How Theory-Informed Priors Affect DESI Evidence for Evolving Dark Energy
Michael W. Toomey, Gabriele Montefalcone, Evan McDonough +1
Recent measurements of baryon acoustic oscillations (BAO) from the Dark Energy Spectroscopic Instrument (DESI) have been interpreted to suggest that dark energy may be evolving. In…
Explaining the "too massive" high-redshift galaxies in JWST data: numerical study of three effects and a simple relation
Joshua J. Ziegler, Katherine Freese, Jonathan Lozano +1
The James Webb Space Telescope has discovered high luminosity galaxies that appear to be "too many" and "too massive" compared to predictions of the Standard LCDM cosmology, sugges…
Thermal Gravitons from Warm Inflation
Gabriele Montefalcone, Barmak Shams Es Haghi, Tao Xu +1
In warm inflation (WI), the persistent thermal bath that is sustained by dissipative interactions with the inflaton field produces a stochastic background of gravitational waves (G…
Model-Independent Dark Energy Measurements from DESI DR2 and Planck 2015 Data
Yun Wang, Katherine Freese
Using DESI DR2 baryon acoustic oscillation (BAO) distance measurements and Planck cosmic microwave background distance priors, we have measured the dark energy density and…
Can a Breakdown of Hawking Evaporation Open a New Mass Window for Primordial Black Holes as Dark Matter?
Gabriele Montefalcone, Dan Hooper, Katherine Freese +3
Semi-classical Hawking evaporation is expected to break down at some point in a black hole's evolution as the effects of quantum gravity become important. In particular, it has bee…
Free-Streaming Neutrinos and Their Phase Shift in Current and Future CMB Power Spectra
Gabriele Montefalcone, Benjamin Wallisch, Katherine Freese
The cosmic neutrino background and other light relics leave distinct imprints in the cosmic microwave background anisotropies through their gravitational influence. Since neutrinos…
