Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17
Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
Revisiting the Chern-Simons interaction during inflation with a non-canonical pseudo-scalar
Jun'ya Kume, Marco Peloso, Nicola Bartolo
A Chern-Simons interaction between a pseudo-scalar field and a U(1) gauge field results in the generation of a chiral gravitational wave background. The detection of this signal is…
Assessing the Impact of Unequal Noises and Foreground Modeling on SGWB Reconstruction with LISA
Jun'ya Kume, Marco Peloso, Mauro Pieroni +1
In the search for stochastic gravitational wave backgrounds (SGWB) of cosmological origin with LISA, it is crucial to account for realistic complications in the noise and astrophys…
Gravitational effects on fluid dynamics in cosmological first-order phase transitions
Ryusuke Jinno, Jun'ya Kume
Cosmological first-order phase transition (FOPT) sources the stochastic gravitational wave background (SWGB) through bubble collisions, sound waves, and turbulence. So far, most st…
On the inefficiency of fermion level-crossing under the parity-violating spin-2 gravitational field
Kohei Kamada, Jun'ya Kume
Gravitational chiral anomaly connects the topological charge of spacetime and the chirality of fermions. It has been known that the chirality is carried by the particles (or the ex…
Revised bounds on local cosmic strings from NANOGrav observations
Jun'ya Kume, Mark Hindmarsh
In a recent paper, the NANOGrav collaboration studied new physics explanations of the observed pulsar timing residuals consistent with a stochastic gravitational wave background (S…
Super-slow phase transition catalyzed by BHs and the birth of baby BHs
Ryusuke Jinno, Jun'ya Kume, Masaki Yamada
We discuss the unique phenomenology of first-order phase transitions catalyzed by primordial black holes (BHs). If the number of BHs within one Hubble volume is smaller than unity…
