A Strong Cosmologically Coupled Mass Growth Solution in Linearized General Relativity
Kevin S. Croker, Joshua Cohon, Viktor T. Toth +13
DESI Data Release 2 has heightened interest in cosmologically coupled black holes (CCBHs) as an explanation for accelerating late-time expansion, but known models for CCBHs grow to…
Dark Radiation Sticks Together: Dark QCD and the Hubble Tension
Matthew R. Buckley, Nicolas Fernandez, Eric Putney
We introduce a model of dark matter charged under a new confining gauge group akin to the Standard Model's quantum chromodynamics (QCD). The fermionic sector contains both heavy an…
General Constraints on Isocurvature from the CMB and Ly- Forest
Matthew R. Buckley, Peizhi Du, Nicolas Fernandez +1
Current cosmological data are well-described by the Lambda-Cold Dark Matter (CDM) model, which assumes adiabatic initial conditions for the primordial density perturbations. Thi…
Force-feeding Supermassive Black Holes with Dissipative Dark Matter
Matthew R. Buckley, Nicolas Fernandez
Supermassive black holes with masses have been discovered by JWST at high redshifts (). It is difficult to explain such objects as the result of ac…
DESI Dark Energy Time Evolution is Recovered by Cosmologically Coupled Black Holes
Kevin S. Croker, Gregory Tarlé, Steve P. Ahlen +4
Recent baryon acoustic oscillation (BAO) measurements by the Dark Energy Spectroscopic Instrument (DESI) provide evidence that dark energy (DE) evolves with time, as parameterized…
Dark Radiation Isocurvature from Cosmological Phase Transitions
Matthew R. Buckley, Peizhi Du, Nicolas Fernandez +1
Cosmological first order phase transitions are typically associated with physics beyond the Standard Model, and thus of great theoretical and observational interest. Models of phas…
