Linear models for systematics and nuisances
Rodrigo Luger, Daniel Foreman-Mackey, David W. Hogg
The target of many astronomical studies is the recovery of tiny astrophysical signals living in a sea of uninteresting (but usually dominant) noise. In many contexts (i.e., stellar…
A pixel-level model for event discovery in time-domain imaging
Dun Wang, David W. Hogg, Daniel Foreman-Mackey +1
Difference imaging or image subtraction is a method that measures differential photometry by matching the pointing and point-spread function (PSF) between image frames. It is used…
Inferring probabilistic stellar rotation periods using Gaussian processes
Ruth Angus, Timothy Morton, Suzanne Aigrain +2
Variability in the light curves of spotted, rotating stars is often non-sinusoidal and quasi-periodic --- spots move on the stellar surface and have finite lifetimes, causing stell…
Seeing double with K2: Testing re-inflation with two remarkably similar planets around red giant branch stars
Samuel K. Grunblatt, Daniel Huber, Eric Gaidos +15
Despite more than 20 years since the discovery of the first gas giant planet with an anomalously large radius, the mechanism for planet inflation remains unknown. Here, we report t…
Long Term Photometric Variability in Kepler Full Frame Images: Magnetic Cycles of Sun-Like Stars
Benjamin T. Montet, Guadalupe Tovar, Daniel Foreman-Mackey
Photometry from the Kepler mission is optimized to detect small, short duration signals like planet transits at the expense of long-term trends. This long-term variability can be r…
