Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
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…
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…
Dispersion Measures of Fast Radio Bursts through the Epoch of Reionization
Joshua J. Ziegler, Paul R. Shapiro, Taha Dawoodbhoy +13
Dispersion measures (DM) of fast radio bursts (FRBs) probe the density of electrons in the intergalactic medium (IGM) along their lines-of-sight, including the average density vers…
Defying eternal inflation in warm inflation with a negative running
Gabriele Montefalcone, Rudnei O. Ramos, Gustavo S. Vicente +1
It was pointed out previously~\cite{Kinney:2014jya} that a sufficiently negative running of the spectral index of curvature perturbations from (ordinary i.e. cold) inflation is abl…
CMB B-mode non-Gaussianity: optimal bispectrum estimator and Fisher forecasts
Adriaan J. Duivenvoorden, P. Daniel Meerburg, Katherine Freese
Upcoming cosmic microwave background (CMB) data can be used to explore harmonic 3-point functions that involve the B-mode component of the CMB polarization signal. We focus on bisp…
