Quintessence and phantoms in light of DESI 2025

Ioannis D. Gialamas, Gert Hütsi, Martti Raidal +3

We analyse DESI BAO, CMB, and supernova data to explore the physical origin of the DESI indication for dynamical dark energy. Beyond the standard CPL parametrization, we explore tr…

Statistics of the supermassive black hole gravitational wave background anisotropy

Juhan Raidal, Juan Urrutia, Ville Vaskonen +1

We study the statistical properties of the anisotropy in the gravitational wave (GW) background originating from supermassive black hole (SMBH) binaries. We derive the distribution…

Thermalization effects on the dynamics of growing vacuum bubbles

Tomasz Krajewski, Marek Lewicki, Martin Vasar +3

We study the evolution of growing vacuum bubbles. The bubble walls interact with the surrounding fluid and may, consequently, reach a terminal velocity. If the mean free path of th…

Primordial black holes and inflation from double-well potentials

Alexandros Karam, Niko Koivunen, Eemeli Tomberg +2

We investigate the formation of large peaks in the inflationary curvature power spectrum from double-well potentials. In such scenarios, the initial CMB spectrum is created at larg…

Reply to "Comment on: Cosmological black holes are not described by the Thakurta metric"

Gert Hütsi, Tomi Koivisto, Martti Raidal +2

In this reply, we address the comment [arXiv:2105.14908] to our recent paper [arXiv:2105.09328], where we argued that the Thakurta metric does not describe cosmological black holes…

Formation and Evolution of Primordial Black Hole Binaries in the Early Universe

Martti Raidal, Christian Spethmann, Ville Vaskonen +1

The abundance of primordial black holes (PBHs) in the mass range can potentially be tested by gravitational wave observations due to the large merger rate of P…
