LIGO’s gravitational waves (GWs) detection has inaugurated an era to test the foundations of gravity. This includes also probing the nature of Dark Energy. Theories explaining the present acceleration of the Universe beyond the cosmological constant typically require adding extra gravitational degrees of freedom. This can lead to distinct signatures in the propagation of GWs. […]

Neutrinoless double beta (0νββ) decay is the only process which can feasibly investigate the Majorana nature of neutrinos and total lepton number conservation. A broad international experimental program requiring considerable resources is being mounted to search for 0νββ decay in the region of parameter space allowed for Inverted Ordering. The Bayesian discovery probability of future […]

In the era of precision cosmology, systematic uncertainty is quickly becoming the limiting factor in modern cosmological analyses. In my work, I discuss a method for performing supernova analyses by combining a hierarchical Bayesian framework with Monte-Carlo simulation realisations. This gains both the flexibility and speed of an analytic analysis along with the nuance and […]

The Milky Way's dust is of basic importance in astronomy. It is both crucial to the formation of stars and is a pervasive observational nuisance. Despite the dust's importance, existing dust maps are largely limited to two dimensions, with the distance to the dust unknown. The advent of large surveys like Pan-STARRS1 has allowed us […]
