Bimetric gravity improves the fit to DESI BAO and eases the Hubble tension
Marcus Högås, Edvard Mörtsell
We investigate whether the latest combination of DESI DR2 baryon acoustic oscillation (BAO) measurements, cosmic microwave background (CMB) data (Planck 2018 + ACT), and Type Ia su…

On the stability of bimetric structure formation
Marcus Högås, Francesco Torsello, Edvard Mörtsell
Bimetric gravity can reproduce the accelerated expansion of the Universe, without a cosmological constant. However, the stability of these solutions to linear perturbations has bee…

Spherical dust collapse in bimetric relativity: Bimetric polytropes
Mikica Kocic, Francesco Torsello, Marcus Högås +1
We present a method for solving the constraint equations in the Hassan-Rosen bimetric theory to determine the initial data for the gravitational collapse of spherically symmetric d…
