Search for Planetary-mass Black Holes with an Improved Viterbi Algorithm
Raul Rodriguez, George Alestas, Sachiko Kuroyanagi +1
Primordial black holes in the planetary-mass range have attracted renewed interest; however, the search for gravitational waves from such binaries remains challenging due to their…
DESI constraints on two-field quintessence with exponential potentials
George Alestas, Marienza Caldarola, Indira Ocampo +2
The paper examines a dark‑energy model with two scalar fields having double‑exponential potentials that together behave like a single shallow potential, and tests its viability usi…
The Topology of the Universe
Craig J. Copi, Deyan P. Mihaylov, Anna Negro +14
Is the Universe infinite in all directions? The only way to know is to look. A non-trivial cosmic topology would imprint subtle signatures on the cosmic microwave background (CMB)…
DESI and Gravitational Wave Constraints Challenge Quintessential α-Attractor Inflation
Changcheng Jing, George Alestas, Sachiko Kuroyanagi
Quintessential inflation models provide a framework that simultaneously describes inflation and dynamical dark energy, the latter of which has recently received growing support fro…
Quantum Signatures of Cosmic Topology: How Casimir Backreaction Transmits Isotropy Violation
Anna Negro, Kurt Hinterbichler, Glenn D. Starkman +17
A finite, scheme-independent Casimir contribution to the stress-energy tensor arises naturally for quantum fields in universes with non-trivial spatial topology. We compute this Ca…
Cosmic topology. Part IIc. Detectability with non-standard primordial power spectrum
Joline Noltmann, Andrius Tamosiunas, Deyan P. Mihaylov +13
Non-trivial spatial topology of the Universe can imprint potentially observable signatures on the cosmic microwave background (CMB). In this study, we investigate how deviations fr…
