The Astrophysical Journal, 2023 With the growing number of binary black hole (BBH) mergers detected by LIGO/Virgo/KAGRA, several systems have become difficult to explain via isolated binary evolution, having components in the pair-instability mass gap, high orbital eccentricities, and ...

Laboratory sources of gravitational waves
Journal of Physics: Conference Series, 2020 Abstract We consider the possibility of generating and subsequently detecting artificial gravitational waves in a laboratory based on different approaches. As one of the methods for creating gravitational waves, we investigate oscillations of the ions of the crystal lattice of a dielectric under the influence of high-power laser ...

Localizing Dynamically Formed Black Hole Binaries in Milky Way Globular Clusters with LISA
The Astrophysical Journal LettersThe dynamical formation of binary black holes (BBHs) in globular clusters (GCs) may contribute significantly to the observed gravitational-wave (GW) merger rate.

Fast Radio Bursts: Electromagnetic Counterparts to Extreme Mass-ratio Inspirals
The Astrophysical Journal Letters, 2023 Recent observations discovered that some repeating fast radio bursts (FRBs) show a large value and complex variations of Faraday rotation measures (RMs).

Machine Learning Confirms GW231123 is a “Lite” Intermediate Mass Black Hole Merger
The Astrophysical Journal LettersThe LIGO–Virgo–KAGRA Collaboration recently reported GW231123, a black hole merger with total mass of around 190–265 M _⊙ . This event adds to the growing evidence of “lite” intermediate mass black hole (IMBH) discoveries of postmerger black holes ≳100 M

Gravitational Waves from Gravitational Collapse
Living Reviews in Relativity, 2011 Gravitational-wave emission from stellar collapse has been studied for nearly four decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat ...

Structure and Skewness of the Effective Inspiral Spin Distribution of Binary Black Hole Mergers
The Astrophysical JournalThe detection of gravitational waves has brought to light a population of binary black holes that merge within a Hubble time. Multiple formation channels can contribute to this population, making it difficult to definitively associate particular ...

Gravitational wave denoising of binary black hole mergers with deep learning
Physics Letters B, 2020 Gravitational wave detection requires an in-depth understanding of the physical properties of gravitational wave signals, and the noise from which they are extracted.

The Astrophysical JournalAnisotropic stochastic gravitational wave background (SGWB) serves as a potential probe of the large-scale structure (LSS) of the universe. In this work, we explore the anisotropic SGWB from local ( z < ∼ 0.085) merging stellar mass compact binaries ...
