Title: Time Series Analysis in Astronomy
Abstract: Repeated observations of sources, and hence derived time series, are ubiquitous in astronomy. I will present several examples of current and future opportunities and challenges for statistical methodology that arise when devising analyses relating such data to underlying scientific questions. In particular, I will discuss the search for occultations of stars by Kuiper Belt objects, conducted by the Taiwanese-American Occultation Survey, the statistical problem of estimating the periods and phased light curves of variable stars, and searching for periodic patterns in point processes generated from the arrival times of gamma-rays from Pulsars. Recently, I have been participating in an interdisciplinary group, the Center for Time Domain Informatics (https://sites.google.com/site/cftdinfo), and I will briefly describe some that group’s current and future interests, centering around the detection and identification of transient sources.
