A New Approach to Periodicity Detection by Prof. Shay Zucker (Tel-Aviv University)<\/p>\n
In Astronomy, periodicity is pervasive in many forms: from rotation of asteroids,<\/p>\n
through the orbits of binary stars, to stellar orbits around the Galactic Center. Thus,<\/p>\n
detecting periodicity in astronomical data, which are often sparse and unevenly<\/p>\n
sampled, has always been a staple of astronomical research. Astronomers use an<\/p>\n
arsenal of methods to perform the task, none of them is perfect, and most of them<\/p>\n
rely on some arbitrary assumptions or parameters. The most popular ones are<\/p>\n
usually inspired by Fourier theory and essentially search for sinusoidal periodicities.<\/p>\n
This talk will present a novel approach to periodicity detection \u2013 the Phase Distance<\/p>\n
Correlation periodogram (PDC) – which is nonparametric, model independent and<\/p>\n
computationally elegant. PDC is an application of some very recent developments in<\/p>\n
statistics, and it opens up new horizons in the field of periodicity detection. It can<\/p>\n
easily be extended to detect periodicities of new and unknown types, in various<\/p>\n
modalities of data, not necessarily in Astronomy.<\/p>\n
The talk will introduce the basic ideas of PDC, highlight its novelty, and demonstrate<\/p>\n
its advantages in some types of data.<\/p>\n
