Gravitational waves (GWs) were recently detected for the first time. This revolutionary
discovery opens a new way of learning about particle physics through GWs from first-order …

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 …

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 …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

Composite topological structures such as superheavy “quasistable strings”(QSS) and “walls
bounded by strings”(WBS) arise in realistic extensions of the Standard Model of high energy …

TianQin is a planned space-based gravitational wave (GW) observatory consisting of three
Earth-orbiting satellites with an orbital radius of about. The satellites will form an equilateral …

A stochastic background of gravitational waves could be created by the superposition of a
large number of independent sources. The physical processes occurring at the earliest …

The terminal wall velocity of a first-order phase transition bubble in the early Universe can
be calculated from a set of fluid equations describing the scalar fields and the plasma's state …

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 …
