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 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…

Astrometric constraints on stochastic gravitational wave background with neural networks

Marienza Caldarola, Gonzalo Morrás, Santiago Jaraba +3

Astrometric measurements provide a unique avenue for constraining the stochastic gravitational wave background (SGWB). In this work, we investigate the application of two neural ne…

DESI constraints on -attractor inflationary models

George Alestas, Marienza Caldarola, Sachiko Kuroyanagi +1

The recent results on the baryon acoustic oscillations measurements from the DESI collaboration have shown tantalizing hints for a time-evolving dark energy equation of state param…

Comparative analysis of the NANOgrav Hellings-Downs as a window into new physics

Rubén Arjona, Savvas Nesseris, Sachiko Kuroyanagi

Pulsar timing array (PTA) experiments have recently provided strong evidence for the signal of the stochastic gravitational wave background (SGWB) in the nHz-frequency band. These…

Mass octupole and current quadrupole corrections to gravitational wave emission from close hyperbolic encounters

Alexander Roskill, Marienza Caldarola, Sachiko Kuroyanagi +1

In this paper, we study the next-to-leading order corrections in the mass multipole expansion, i.e. the mass octupole and current quadrupole, to gravitational wave production by cl…
