Unbiased Hubble constant estimation from binary neutron star mergers
Daniel J. Mortlock, Stephen M. Feeney, Hiranya V. Peiris +2
Gravitational wave (GW) observations of binary neutron star (BNS) mergers can be used to measure luminosity distances and hence, when coupled with estimates for the mergers' host r…
Impact of using the ultra-high-energy cosmic ray arrival energies to constrain source associations
Francesca Capel, Daniel J. Mortlock
We present a Bayesian hierarchical model which enables a joint fit of the ultra-high-energy cosmic ray (UHECR) energy spectrum and arrival directions within the context of a physic…
Inferring properties of the local white dwarf population in astrometric and photometric surveys
Axel Widmark, Daniel J. Mortlock, Hiranya V. Peiris
The Gaia mission will provide precise astrometry for an unprecedented number of white dwarfs (WDs), encoding information on stellar evolution, Type Ia supernovae progenitor scenari…
Prospects for resolving the Hubble constant tension with standard sirens
Stephen M. Feeney, Hiranya V. Peiris, Andrew R. Williamson +4
The Hubble constant () estimated from the local Cepheid-supernova (SN) distance ladder is in 3- tension with the value extrapolated from cosmic microwave background (CMB) d…
