Detection of anomalies amongst LIGO's glitch populations with autoencoders
Paloma Laguarta, Robin van der Laag, Melissa Lopez +9
Gravitational-wave (GW) interferometers are able to detect a change in distance of 1/10,000th the size of a proton. Such sensitivity leads to large appearance rates of non-G…
Comparing gravitational waveform models for binary black hole mergers through a hypermodels approach
Anna Puecher, Anuradha Samajdar, Gregory Ashton +2
The inference of source parameters from gravitational-wave signals relies on theoretical models that describe the emitted waveform. Different model assumptions on which the computa…
Relative binning for complete gravitational-wave parameter estimation with higher-order modes and precession, and applications to lensing and third-generation detectors
Harsh Narola, Justin Janquart, Quirijn Meijer +2
Once a gravitational wave signal is detected, the measurement of its source parameters is important to achieve various scientific goals. This is done through Bayesian inference, wh…
How well can modified gravitational wave propagation be constrained with strong lensing?
Harsh Narola, Justin Janquart, Leïla Haegel +3
Strong gravitational lensing produces multiple images of a gravitational wave (GW) signal, which can be observed by detectors as time-separated copies of the same event. It has bee…
Probing Quarkyonic Matter in Neutron Stars with the Bayesian Nuclear-Physics Multi-Messenger Astrophysics Framework
Peter T. H. Pang, Lars Sivertsen, Rahul Somasundaram +5
The interior of neutron stars contains matter at the highest densities realized in our Universe. Interestingly, theoretical studies of dense matter, in combination with the existen…
The Return of GOLUM: Improving Distributed Joint Parameter Estimation for Strongly-Lensed Gravitational Waves
Justin Janquart, K. Haris, Otto A. Hannuksela +1
Owing to the forecasted improved sensitivity of ground-based gravitational-wave detectors, new research avenues will become accessible. This is the case for gravitational-wave stro…
Revealing the strength of three-nucleon interactions with the Einstein Telescope
Henrik Rose, Nina Kunert, Tim Dietrich +5
Three-nucleon forces are crucial for the accurate description of nuclear systems, including dense matter probed in neutron stars. We explore nuclear Hamiltonians that reproduce two…
