Eccentric Binaries Accreting from Thin Disks: Orbital Evolution

Alexander J. Dittmann, Geoffrey Ryan, Luciano Combi

Circumbinary disks crucially affect the orbital and electromagnetic properties of binary systems across the universe, from stars in our galactic neighborhood to supermassive black…

The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs

Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16

Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…

Indirect forces in disc-planet interaction

Roman R. Rafikov, Nicolas P. Cimerman, Callum W. Fairbairn +1

Gravitational coupling between a protoplanetary disc and an embedded planet is often studied in a frame attached to a central star. This frame is non-inertial because of the stella…

Pushing the limits of eccentricity in planet-disc interactions

Callum W. Fairbairn, Alexander J. Dittmann

Modelling the gravitational interaction between an eccentric perturber and a differentially shearing gas disc is a longstanding problem with various astrophysical applications, ran…

The Multiple Paths to Merger of Unequal-Mass Black Hole Binaries in the Disks of Active Galactic Nuclei

Alexander J. Dittmann, Adam M. Dempsey, Hui Li

The accretion disks that power active galactic nuclei (AGN) are thought to house populations of stars and compact objects; after forming binaries these compact objects may merge, b…

The SHMS 11 GeV/c Spectrometer in Hall C at Jefferson Lab

S. Ali, A. Ahmidouch, G. R. Ambrose +72

The Super High Momentum Spectrometer (SHMS) has been built for Hall C at the Thomas Jefferson National Accelerator Facility (Jefferson Lab). With a momentum capability reaching 11…
