Dirichlet Process Gaussian-mixture model: An application to localizing coalescing binary neutron stars with gravitational-wave observations

1 code implementation24 Jan 2018 Walter Del Pozzo, Christopher Berry, Archisman Ghosh, Tom Haines, Leo Singer, Alberto Vecchio

We reconstruct posterior distributions for the position (sky area and distance) of a simulated set of binary neutron-star gravitational-waves signals observed with Advanced LIGO and Advanced Virgo.

Delayed rejection schemes for efficient Markov-Chain Monte-Carlo sampling of multimodal distributions

1 code implementation14 Apr 2009 Miquel Trias, Alberto Vecchio, John Veitch

A number of problems in a variety of fields are characterised by target distributions with a multimodal structure in which the presence of several isolated local maxima dramatically reduces the efficiency of Markov Chain Monte Carlo sampling algorithms.
