Gravitational memory meets astrophysical environments: exploring a new frontier through osculations
Rishabh Kumar Singh, Shailesh Kumar, Abhishek Chowdhuri +1
We study how dark matter environments influence nonlinear gravitational memory from intermediate-mass-ratio binaries. Incorporating environmental effects from the dark matter gravi…

Gravitational Radiation from hyperbolic encounters in the presence of dark matter
Abhishek Chowdhuri, Rishabh Kumar Singh, Kaushik Kangsabanik +1
In this study, we look into binaries undergoing gravitational radiation during a hyperbolic passage. Such hyperbolic events can be a credible source of gravitational waves in futur…
