Targeted numerical simulations of binary black holes for GW170104
James Healy, Jacob Lange, Richard O'Shaughnessy +22
In response to LIGO's observation of GW170104, we performed a series of full numerical simulations of binary black holes, each designed to replicate likely realizations of its dyna…
Exploring a search for long-duration transient gravitational waves associated with magnetar bursts
Ryan Quitzow-James, James Brau, James Clark +6
Soft gamma repeaters and anomalous X-ray pulsars are thought to be magnetars, neutron stars with strong magnetic fields of order --$10^{15} \, \mathrm{gauss…
RUNMON-RIFT: Adaptive Configuration and Healing for Large-Scale Parameter Inference
Rhiannon Udall, Joshua Brandt, Grihith Manchanda +5
Gravitational wave parameter inference pipelines operate on data containing unknown sources on distributed hardware with unreliable performance. For one specific analysis pipeline…
Adapting Pretrained Networks for Image Quality Assessment on High Dynamic Range Displays
Andrei Chubarau, Hyunjin Yoo, Tara Akhavan +1
Conventional image quality metrics (IQMs), such as PSNR and SSIM, are designed for perceptually uniform gamma-encoded pixel values and cannot be directly applied to perceptually no…
Gravitational-Wave Detection using Multivariate Analysis
Thomas S. Adams, Duncan Meacher, James Clark +3
Searches for gravitational-wave bursts (transient signals, typically of unknown waveform) require identification of weak signals in background detector noise. The sensitivity of su…
VTAMIQ: Transformers for Attention Modulated Image Quality Assessment
Andrei Chubarau, James Clark
Following the major successes of self-attention and Transformers for image analysis, we investigate the use of such attention mechanisms in the context of Image Quality Assessment…
