Equiaffine Braneworld

Galaxies, 2020
Higher dimensional theories, wherein our four dimensional universe is immersed into a bulk ambient, have received much attention recently, and the directions of investigation had, as far as we can discern, all followed the ordinary Euclidean hypersurface

Gravitational Wave Astronomy

, 2006
Gravitational wave astronomy is expected to become an observational field within the next decade. First direct detection of gravitational waves is possible with existing terrestrial-based detectors, and highly probable with proposed upgrades.

A new source of phase transition gravitational waves: heavy particle braking across bubble walls

Journal of High Energy Physics
Motivated by the new heavy dark matter production mechanism from cosmic phase transition, we propose a novel mechanism for the generation of microscopic gravitational waves (GWs) during cosmological first-order phase transitions arising from the braking ...

Dealing with data gaps for TianQin with massive black hole binary signal

European Physical Journal C: Particles and Fields
Space-borne gravitational wave detectors like TianQin might encounter data gaps due to factors like micro-meteoroid collisions or hardware failures. Such events will cause discontinuity in the data, presenting challenges to the data analysis for TianQin,

Present and Future of Gravitational Wave Astronomy

, 2022
The first detection on Earth of a gravitational wave signal from the coalescence of a binary black hole system in 2015 established a new era in astronomy, allowing the scientific community to observe the Universe with a new form of radiation for the ...

Testing space-time non-commutativity with TianQin

European Physical Journal C: Particles and Fields
The direct detection of gravitational waves offers a powerful tool to explore the nature of gravity and the structure of space-time. This paper focuses on the capabilities of space-based gravitational wave detectors in testing space-time non ...

No Evidence for a Dip in the Binary Black Hole Mass Spectrum

The Astrophysical Journal
Stellar models indicate that the core compactness of a star, which is a common proxy for its explodability in a supernova, does not increase monotonically with the star’s mass.

Traces of Extra Dimensions in Cosmology [PDF]

, 2010
In this thesis, we discuss the observational consequences of extra dimensions on cosmological phenomena. We begin with an overview of extra dimensions, from the initial ideas of Kaluza and Klein to the more recent concept of braneworld models and in ...

Do Both Black Holes Spin in Merging Binaries? Evidence from GWTC-4 and Astrophysical Implications

The Astrophysical Journal
Angular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores of most black hole progenitors lose almost all of their angular momentum ...
