A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
Fresh Look at Neutrino Self-Interactions With the Lyman- Forest: Constraints from EFT and PRIYA Simulations
Adam He, Mikhail M. Ivanov, Simeon Bird +2
We present the first search for evidence of neutrino self-interaction with two new, state-of-the-art likelihoods for eBOSS Lyman- data. These are an effective field theory (EFT…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Gravitational Waves from Primordial Black Hole Dark Matter Spikes
Wei-Xiang Feng, Simeon Bird, Hai-Bo Yu
The origin of the binary black hole mergers observed by LIGO--Virgo--KAGRA remains an open question. We calculate the merger rate from primordial black holes (PBHs) within the dens…
