De-Trending Time Series for Astronomical Variability Surveys
Dae-Won Kim, Pavlos Protopapas, Charles Alcock +2
We present a de-trending algorithm for the removal of trends in time series. Trends in time series could be caused by various systematic and random noise sources such as cloud pass…
First Results From The Taiwanese-American Occultation Survey (TAOS)
Z. -W. Zhang, F. B. Bianco, M. J. Lehner +22
Results from the first two years of data from the Taiwanese-American Occultation Survey (TAOS) are presented. Stars have been monitored photometrically at 4 Hz or 5 Hz to search fo…
Combined reconstruction of weak and strong lensing data with WSLAP
J. M. Diego, M. Tegmark, P. Protopapas +1
We describe a method to estimate the mass distribution of a gravitational lens and the position of the sources from combined strong and weak lensing data. The algorithm combines we…
Finding outlier light-curves in catalogs of periodic variable stars
P. Protopapas, J. M. Giammarco, L. Faccioli +3
We present a methodology to discover outliers in catalogs of periodic light-curves. We use cross-correlation as measure of ``similarity'' between two individual light-curves and th…
Fast identification of transits from light-curves
Pavlos Protopapas, Raul Jimenez, Charles Alcock
We present an algorithm that allows fast and efficient detection of transits, including planetary transits, from light-curves. The method is based on building an ensemble of fiduci…
Non-parametric mass reconstruction of A1689 from strong lensing data with SLAP
J. M. Diego, H. B. Sandvik, P. Protopapas +3
We present the mass distribution in the central area of the cluster A1689 by fitting over 100 multiply lensed images with the non-parametric Strong Lensing Analysis Package (SLAP,…
