About Geoffrey Ryan

Geoffrey Ryan, With an exceptional h-index of 21 and a recent h-index of 19 (since 2020), a distinguished researcher at University of Maryland, specializes in the field of Gamma-Ray Bursts, General Relativity, Black Holes, Accretion, Fluid Dynamics.

His recent articles reflect a diverse array of research interests and contributions to the field:

Potential biases and prospects for the Hubble constant estimation via electromagnetic and gravitational-wave joint analyses

Scaling relations for gamma-ray burst afterglow light curves and centroid motion independent of jet structure and dynamics

A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst

The Santa Barabara Binary-Disk Code Comparison

Multiwavelength Modeling of Orphan Optical Afterglows

Joint analysis of gravitational-wave and electromagnetic data of mergers: breaking an afterglow model degeneracy in GW170817 and in future events

Multi-messenger signatures of black hole binary-disk interactions in the LISA regime

Binary black hole accretion across the disk and gravitational wave-driven regimes
