Research
I am interested in the dynamics of compact objects and their interactions with astrophysical environments. This includes:
"Gaseous Dynamical Friction on Elliptical Keplerian Orbits" - David O'Neill, Daniel D'Orazio, Johan Samsing, Martin Pessah, ApJ 974 216 (2024)
"Gravitational Wave Decoupling in Retrograde Circumbinary Disks" - David O'Neill (in prep.)
"Gaseous Dynamical Friction on Hyperbolic Encounters" - David O'Neill (in prep.)
"Gravitational Wave Memory Imprints on the CMB from Populations of Massive Black Hole Mergers" - Lorenz Zwick, David O'Neill, Kai Hendriks, Philip Kirkeberg, Miquel Miravet-Tenés (2024)
" Bridging the Micro-Hz Gravitational Wave Gap via Doppler with the Uranus Orbiter and Probe Mission: Massive Black Hole Binaries, Early Universe Signals and Ultr-Light Dark Matter" - Lorenz Zwick, Deniz Soyuer, Daniel J. D'Orazio, David O'Neill, Andrea Derdzinski, Prasenjit Saha, Diego Blas, Alexander C. Jenkins, Luke Zoltan Kelley
