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…
The DES view of the Eridanus supervoid and the CMB Cold Spot
A. Kovács, N. Jeffrey, M. Gatti +119
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground str…
Dark Energy Survey Year 3 results: curved-sky weak lensing mass map reconstruction
N. Jeffrey, M. Gatti, C. Chang +127
We present reconstructed convergence maps, \textit{mass maps}, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted pro…
Investigating Cosmological GAN Emulators Using Latent Space Interpolation
Andrius Tamosiunas, Hans A. Winther, Kazuya Koyama +3
Generative adversarial networks (GANs) have been recently applied as a novel emulation technique for large scale structure simulations. Recent results show that GANs can be used as…
Dark Energy Survey Year 1 Results: Wide field mass maps via forward fitting in harmonic space
B. Mawdsley, D. Bacon, C. Chang +63
We present new wide-field weak lensing mass maps for the Year 1 Dark Energy Survey data, generated via a forward fitting approach. This method of producing maps does not impose any…
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…
Dark Energy Survey Year 1 Results: Curved-Sky Weak Lensing Mass Map
C. Chang, A. Pujol, B. Mawdsley +117
We construct the largest curved-sky galaxy weak lensing mass map to date from the DES first-year (DES Y1) data. The map, about 10 times larger than previous work, is constructed ov…
