Spectroscopy of High-Redshift Supernovae from the ESSENCE Project: The First Four Years
R. J. Foley, T. Matheson, S. Blondin +23
We present the results of spectroscopic observations from the ESSENCE high-redshift supernova (SN) survey during its first four years of operation. This sample includes spectra of…
Time Variability of Quasars: the Structure Function Variance
C. MacLeod, Z. Ivezic, W. de Vries +2
Significant progress in the description of quasar variability has been recently made by employing SDSS and POSS data. Common to most studies is a fundamental assumption that photom…
Parametrization and Classification of 20 Billion LSST Objects: Lessons from SDSS
Z. Ivezic, T. Axelrod, A. C. Becker
The Large Synoptic Survey Telescope (LSST) will be a large, wide-field ground-based system designed to obtain, starting in 2015, multiple images of the sky that is visible from Cer…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
The Peculiar Periodic YSO WL 4 in Rho Ophiuchus
Peter Plavchan, Alan H. Gee, Karl Stapelfeldt +1
We present the discovery of 130.87 day periodic near-infrared flux variability for the Class II T Tauri star WL 4 (= 2MASS J16271848-2429059, ISO-Oph 128). Our data are from the 2M…
Exploring the Outer Solar System with the ESSENCE Supernova Survey
A. C. Becker, K. Arraki, N. A. Kaib +36
We report the discovery and orbit determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging dataset. Two additional objects discovered…
