Testing Quasi-Linear Coasting Cosmologies with Late-Time Large-Scale Structure Growth
Dávid A. Ködmön, Péter Raffai
We derive analytical expressions for the growth factor, , and density-weighted growth rate, , for cosmologies in which at late times. We fit the result…
Statistical evidence for massive black hole recoils in active galactic nuclei
Bence Bécsy, Peter Raffai, Zoltán Haiman +2
We search for a population-level signature of gravitational-wave recoiling supermassive black holes: a positive correlation between dust obscuration and the magnitude of the line-o…
A Case for an Inhomogeneous Einstein-de Sitter Universe
Peter Raffai, Dominika E. R. Kis, Dávid A. Ködmön +3
We present a local-to-global cosmological framework in which cosmic acceleration emerges from structure formation in an inhomogeneous Einstein-de Sitter (iEdS) universe, without da…
Constraints on AvERA Cosmologies from Cosmic Chronometers and Type Ia Supernovae
Adrienn Pataki, Péter Raffai, István Csabai +2
We constrain AvERA cosmologies in comparison with the flat CDM model using cosmic chronometer (CC) data and the Pantheon+ sample of type Ia supernovae (SNe Ia). The analysis in…
Utilizing Stellar Mass Estimates to Identify Gravitational Wave Host Galaxies
M. Pálfi, G. Dálya, P. Raffai
Stellar mass can enhance the ranking of potential hosts for compact binary coalescences identified by ground-based gravitational-wave detectors within large localisation areas cont…
Cosmic chronometers, Pantheon+ supernovae, and quasars favor coasting cosmologies over the flat CDM model
Peter Raffai, Adrienn Pataki, Rebeka L. Böttger +2
We test and compare coasting cosmological models with curvature parameters in units and the flat CDM model by fitting them to co…
