The OGLE View of Microlensing towards the Magellanic Clouds. III. Ruling out sub-solar MACHOs with the OGLE-III LMC data
L. Wyrzykowski, S. Kozlowski, J. Skowron +8
In the third part of the series presenting the Optical Gravitational Lensing Experiment (OGLE) microlensing studies of the dark matter halo compact objects (MACHOs) we describe res…
A sub-Saturn Mass Planet, MOA-2009-BLG-319Lb
N. Miyake, T. Sumi, Subo Dong +119
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K or M-dwarf star in the inner Galactic disk or Galactic bulge. The h…
Quasar Selection Based on Photometric Variability
C. L. MacLeod, K. Brooks, Z. Ivezic +7
We develop a method for separating quasars from other variable point sources using SDSS Stripe 82 light curve data for ~10,000 variable objects. To statistically describe quasar va…
Black Hole Mass Estimates Based on CIV are Consistent with Those Based on the Balmer Lines
R. J. Assef, K. D. Denney, C. S. Kochanek +39
Using a sample of high-redshift lensed quasars from the CASTLES project with observed-frame ultraviolet or optical and near-infrared spectra, we have searched for possible biases b…
SDWFS-MT-1: A Self-Obscured Luminous Supernova at z~0.2
Szymon Kozlowski, C. S. Kochanek, D. Stern +22
We report the discovery of a six-month-long mid-infrared transient, SDWFS-MT-1 (aka SN 2007va), in the Spitzer Deep, Wide-Field Survey of the NOAO Deep Wide-Field Survey Bootes fie…
OGLE 2008--BLG--290: An accurate measurement of the limb darkening of a Galactic Bulge K Giant spatially resolved by microlensing
P. Fouque, D. Heyrovsky, S. Dong +115
Gravitational microlensing is not only a successful tool for discovering distant exoplanets, but it also enables characterization of the lens and source stars involved in the lensi…
The OGLE View of Microlensing towards the Magellanic Clouds. II. OGLE-II SMC data
L. Wyrzykowski, S. Kozlowski, J. Skowron +8
The primary goal of this paper is to provide the evidence that can either prove or falsify the hypothesis that dark matter in the Galactic halo can clump into stellar-mass compact…
Modeling the Time Variability of SDSS Stripe 82 Quasars as a Damped Random Walk
C. L. MacLeod, Ž. Ivezić, C. S. Kochanek +10
We model the time variability of ~9,000 spectroscopically confirmed quasars in SDSS Stripe 82 as a damped random walk. Using 2.7 million photometric measurements collected over 10…
Mid-Infrared Variability from the Spitzer Deep, Wide-Field Survey
Szymon Kozlowski, Christopher S. Kochanek, Daniel Stern +30
We use the multi-epoch, mid-infrared Spitzer Deep, Wide-Field Survey to investigate the variability of 474,179 objects in 8.1 deg^2 of the NDWFS Bootes field. We perform a Differen…
