Gravitational waves triggered by $B-L$ charged hidden scalar and leptogenesis

We study the electroweak symmetry breaking in the framework of a classically conformal $U(1)_{B-L}$ theory, where three right-handed neutrinos (RHNs) and a hidden scalar are introduced, with the latter playing the role of dark matter (DM). Expand abstract.

The Fredholm Approach to Charactize Gravitational Wave Echoes

Constraints on primordial curvature perturbations from primordial black hole dark matter and secondary gravitational waves

For secondary gravitational waves produced after the horizon reentry, we derive an analytical formula for the time integral of the source and analytical behavior of the time dependence of the energy density of induced gravitational waves is obtained. Expand abstract.

Neutron Star Merger Afterglows: Population Prospects for the Gravitational Wave Era

Through prescribing a population of mergers and modelling their afterglows, we study the diversity of those events to be observed jointly in gravitational waves and electromagnetic bands. Expand abstract.

Parametric solutions of the generalized short pulse equations

The cycloid reduced from the periodic traveling wave with cusps is also worth remarking in connection with Gerstner's trochoidal solution in deep gravity waves. Expand abstract.

Space Based Gravitational Wave Astronomy Beyond LISA

When LISA opens the low-frequency window of the gravitational wave spectrum, around 2034, the surge of gravitational-wave astronomy will strongly compel a subsequent mission to further explore the frequency bands of the GW spectrum that can only be accessed from space. Expand abstract.

Chirping compact stars: gravitational radiation and detection degeneracy with binary systems A conceptual pathfinder for space-based gravitational-wave observatories

Compressible, Riemann S-type ellipsoids can emit gravitational waves (GWs) with a chirp-like behavior (hereafter chirping ellipsoids, CELs). Expand abstract.

Unique Quantum Topological State with Emergent Quantum Gravity

The topological excitations for the system are fermions that are really the unit of the topological spinor spacetime and the collective excitations are spinor-waves that are really spin-2 gravitational waves. Expand abstract.
