A transdimensional sampling framework for pulsar timing noise modelling
Valentina Di Marco, Nir Guttman, Matthew T. Miles +3
A careful characterisation of the noise processes in pulsar timing data is a prerequisite for pulsar timing array experiments. While single-pulsar noise analyses are crucial for bo…
Trends in the Population of Binary Black Holes Following the Fourth Gravitational-Wave Transient Catalog: a Data-Driven Analysis
Nir Guttman, Ethan Payne, Paul D. Lasky +1
Current population models of binary black hole distributions are difficult to interpret because standard population inferences hinge on modeling choices, which can mask or mimic re…
Do both black holes spin in merging binaries? Evidence from GWTC-4 and astrophysical implications
Christian Adamcewicz, Nir Guttman, Paul D. Lasky +1
Angular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores…
Modelling noise in gravitational-wave observatories with transdimensional models
Nir Guttman, Paul D. Lasky, Eric Thrane
Modelling noise in gravitational-wave observatories is crucial for accurately inferring the properties of gravitational-wave sources. We introduce a transdimensional Bayesian appro…
