The Intrinsic Alignment of Red Galaxies in DES Y1 redMaPPer Galaxy Clusters
C. Zhou, A. Tong, M. A. Troxel +79
Clusters of galaxies are sensitive to the most nonlinear peaks in the cosmic density field. The weak gravitational lensing of background galaxies by clusters can allow us to infer…
Taking a break: paused accretion in the symbiotic binary RT Cru
A. Pujol, G. J. M. Luna, K. Mukai +10
Symbiotic binaries sometimes hide their symbiotic nature for significant periods of time. There is mounting observational evidence that in those symbiotics that are powered solely…
ShapePipe: a new shape measurement pipeline and weak-lensing application to UNIONS/CFIS data
Axel Guinot, Martin Kilbinger, Samuel Farrens +16
UNIONS is an ongoing collaboration that will provide the largest deep photometric survey of the Northern sky in four optical bands to date. As part of this collaboration, CFIS is t…
Shear measurement bias II: a fast machine learning calibration method
Arnau Pujol, Jerome Bobin, Florent Sureau +2
We present a new shear calibration method based on machine learning. The method estimates the individual shear responses of the objects from the combination of several measured pro…
Euclid Preparation IV. Impact of undetected galaxies on weak-lensing shear measurements
Euclid Collaboration, N. Martinet, T. Schrabback +22
In modern weak-lensing surveys, the common approach to correct for residual systematic biases in the shear is to calibrate shape measurement algorithms using simulations. These sim…
Cosmological lensing ratios with DES Y1, SPT and Planck
J. Prat, E. J. Baxter, T. Shin +131
Correlations between tracers of the matter density field and gravitational lensing are sensitive to the evolution of the matter power spectrum and the expansion rate across cosmic…
