Evaluating Deep Learning Models for Multiclass Classification of LIGO Gravitational-Wave Glitches
Rudhresh Manoharan, Gerald Cleaver
Gravitational-wave detectors are affected by short-duration non-Gaussian noise transients, commonly referred to as glitches, which can obscure astrophysical signals and complicate…

Scalar-Field Wave Dynamics and Quasinormal Modes of the Teo Rotating Wormhole
Ramesh Radhakrishnan, Gerald Cleaver, Delaram Mirfendereski +2
We investigate scalar field perturbations of the rotating Teo wormhole. We also compute the quasinormal mode (QNM) spectrum using first order WKB approximation. After separation of…

Gauge-Invariant Gravitational Wave Polarization in Metric f(R) Gravity with Cosmological Implications
Ramesh Radhakrishnan, David McNutt, Delaram Mirfendereski +4
We develop a fully gauge invariant analysis of gravitational wave polarizations in metric f(R) gravity with a particular focus on the modified Starobinsky model, whose constant cur…
