MOA-2013-BLG-220Lb: Massive Planetary Companion to Galactic-Disk Host
J. C. Yee, C. Han, A. Gould +70
We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass ratio relative to its host. The proper motion, $μ=12.5\pm 1\, {\rm mas…
The picasso gas model: Painting intracluster gas on gravity-only simulations
F. Kéruzoré, L. E. Bleem, N. Frontiere +5
We introduce picasso, a model designed to predict thermodynamic properties of the intracluster medium based on the properties of halos in gravity-only simulations. The predictions…
OGLE-2013-BLG-0102LA,B: Microlensing binary with components at star/brown-dwarf and brown-dwarf/planet boundaries
Y. K. Jung, A. Udalski, T. Sumi +51
We present the analysis of the gravitational microlensing event OGLE-2013-BLG-0102. The light curve of the event is characterized by a strong short-term anomaly superposed on a smo…
Dark Energy Survey Year 1 Results: Constraints on Intrinsic Alignments and their Colour Dependence from Galaxy Clustering and Weak Lensing
S. Samuroff, J. Blazek, M. A. Troxel +70
We perform a joint analysis of intrinsic alignments and cosmology using tomographic weak lensing, galaxy clustering and galaxy-galaxy lensing measurements from Year 1 (Y1) of the D…
Optimization and Quality Assessment of Baryon Pasting for Intracluster Gas using the Borg Cube Simulation
F. Kéruzoré, L. E. Bleem, M. Buehlmann +5
Synthetic datasets generated from large-volume gravity-only simulations are an important tool in the calibration of cosmological analyses. Their creation often requires accurate in…
A Terrestrial Planet in a ~1 AU Orbit Around One Member of a ~15 AU Binary
A. Gould, A. Udalski, I. -G. Shin +61
We detect a cold, terrestrial planet in a binary-star system using gravitational microlensing. The planet has low mass (2 Earth masses) and lies projected at ~ 0.8 a…
Optimization of Weak Lensing Lightcone Simulations for Higher-Order Statistics in the LSST era
J. Mena-Fernández, C. Doux, J. Harnois-Déraps +9
We present a framework for generating lightcone simulations tailored to the analysis of Stage-IV cosmic shear data using Higher-Order Statistics (HOS). We revisit key design choice…
Non-linear infusion of intrinsic alignment and source clustering: impact on non-Gaussian cosmic shear statistics
J. Harnois-Déraps, N. Å arÄeviÄ, L. Medina Varela +15
Intrinsic alignments (IA) of galaxies is one of the key secondary signals to cosmic shear measurements, and must be modeled to interpret weak lensing data and infer the correct cos…
The catalog-to-cosmology framework for weak lensing and galaxy clustering for LSST
J. Prat, J. Zuntz, Y. Omori +20
We present TXPipe, a modular, automated and reproducible pipeline for ingesting catalog data and performing all the calculations required to obtain quality-assured two-point measur…
Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing
D. Kirk, Y. Omori, A. Benoit-Lévy +89
We measure the cross-correlation between weak lensing of galaxy images and of the cosmic microwave background (CMB). The effects of gravitational lensing on different sources will…
