A statistical primer on classical period-finding techniques in astronomy

Shaban, Ahmed; Giertych, Naomi; Haravu, Pragya +1 more

The aim of our paper is to investigate the properties of the classical phase-dispersion minimization (PDM), analysis of variance (AOV), string-length (SL), and Lomb-Scargle (LS) power statistics from a statistician's perspective. We confirm that when the data are perturbations of a constant function, i.e. under the null hypothesis of no period in …

Dark matter local density determination: recent observations and future prospects

Widmark, A.; de Salas, Pablo F.

This report summarises progress made in estimating the local density of dark matter (ρ_DM,⊙), a quantity that is especially important for dark matter direct detection experiments. We outline and compare the most common methods to estimate ρ_DM,⊙ and the results from recent studies, including those that have benefited from the o…
