Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

The 100 years since the publication of Albert Einstein's theory of general relativity saw
significant development of the understanding of the theory, the identification of potential …

We revisit the possibility that the stochastic common-spectrum process recently detected by
the NANOGrav pulsar timing array experiment could be due to primordial gravitational …

The current cosmological model requires new physics beyond the standard model of
elementary particles and fields, such as dark matter and dark energy. Their nature is …

Abstract The Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is a future
Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the …

We calculate the gravitational-wave (GW) signatures of detailed three-dimensional (3D) core-
collapse supernova simulations spanning a range of massive stars. Most of the simulations …

We propose a space-based interferometer surveying the gravitational wave (GW) sky in the
milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in …

In this study, the gravitational deflection angle of photons in the weak field limit (or the weak
deflection angle) and shadow cast by the electrically charged and spherically symmetric …
