EVEREST: Pixel Level Decorrelation of K2 Light curves
Rodrigo Luger, Eric Agol, Ethan Kruse +4
We present EVEREST, an open-source pipeline for removing instrumental noise from K2 light curves. EVEREST employs a variant of pixel level decorrelation (PLD) to remove systematics…
First-Year Spectroscopy for the SDSS-II Supernova Survey
Chen Zheng, Roger W. Romani, Masao Sako +77
This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band…
Efficient use of simultaneous multi-band observations for variable star analysis
Maria Süveges, Paul Bartholdi, Andrew Becker +3
The luminosity changes of most types of variable stars are correlated in the different wavelengths, and these correlations may be exploited for several purposes: for variability de…
Lightcurves of Type Ia Supernovae from Near the Time of Explosion
Arti Garg, Christopher W. Stubbs, Peter Challis +18
We present a set of 11 type Ia supernova (SN Ia) lightcurves with dense, pre-maximum sampling. These supernovae (SNe), in galaxies behind the Large Magellanic Cloud (LMC), were dis…
The Sloan Digital Sky Survey-II: Photometry and Supernova Ia Light Curves from the 2005 data
Jon A. Holtzman, John Marriner, Richard Kessler +29
We present ugriz light curves for 146 spectroscopically confirmed or spectroscopically probable Type Ia supernovae from the 2005 season of the SDSS-II Supernova survey. The light c…
Measurements of the Rate of Type Ia Supernovae at Redshift z < ~0.3 from the SDSS-II Supernova Survey
Benjamin Dilday, Mathew Smith, Bruce Bassett +33
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate based on data from the Sloan Digital Sky Survey II (SDSS-II) Supernova Survey. The adopted sample of super…
The Large-Scale Extinction Map of the Galactic Bulge from the MACHO Project Photometry
Piotr Popowski, Kem Cook, Andrew Becker
We present a (V-R)-based reddening map of about 43 square degrees of the Galactic bulge/bar. The map is constructed using template image photometry from the MACHO microlensing surv…
The Fall 2004 SDSS Supernova Survey
Masao Sako, Roger Romani, Josh Frieman +38
In preparation for the Supernova Survey of the Sloan Digital Sky Survey (SDSS) II, a proposed 3-year extension to the SDSS, we have conducted an early engineering and science run d…
A Measurement of the Rate of Type Ia Supernovae in Galaxy Clusters from the SDSS-II Supernova Survey
Benjamin Dilday, Bruce Bassett, Andrew Becker +32
ABRIDGED We present measurements of the Type Ia supernova (SN) rate in galaxy clusters based on data from the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. The cluster SN…
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…
First-year Sloan Digital Sky Survey-II (SDSS-II) Supernova Results: Hubble Diagram and Cosmological Parameters
Richard Kessler, Andrew Becker, David Cinabro +43
We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital S…
