Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
Weak Lensing Mass Calibration of the ACT DR5 Galaxy Clusters with the DES Year 3 Weak Lensing Data
T. Shin, E. J. Baxter, E. Lee +93
We use weak gravitational lensing measurements from Year 3 Dark Energy Survey data to calibrate the masses of 443 galaxy clusters selected via the Sunyaev-Zel'dovich effect from At…
Dark Energy Survey Year 6 Results: Redshift Calibration of the Weak Lensing Source Galaxies
B. Yin, A. Amon, A. Campos +95
Determining the distribution of redshifts for galaxies in wide-field photometric surveys is essential for robust cosmological studies of weak gravitational lensing. We present the…
The final WaZP galaxy cluster catalog of the Dark Energy Survey and comparison with SZE data
C. Benoist, M. Aguena, L. da Costa +43
In this work, we present and characterize the galaxy cluster catalog detected by the WaZP cluster finder, which is not based on red-sequence identification, on the full six years o…
The Gravitational Lensing Imprints of DES Y3 Superstructures on the CMB: A Matched Filtering Approach
Umut Demirbozan, Seshadri Nadathur, Ismael Ferrero +63
Low density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence . This effect provides insight into the…
Primordial non-Gaussianity with Angular correlation function: Integral constraint and validation for DES

Local primordial non-Gaussianity (PNG) is a promising observable of the underlying physics of inflation, characterised by . We present the methodology to meas…
Dark Energy Survey Year 3 results: Cosmology with peaks using an emulator approach
D. Zürcher, J. Fluri, R. Sgier +119
We constrain the matter density and the amplitude of density fluctuations within the CDM cosmological model with shear peak statistics and angular converg…
The WaZP galaxy cluster sample of the Dark Energy Survey Year 1
M. Aguena, C. Benoist, L. N. da Costa +57
We present a new (2+1)D galaxy cluster finder based on photometric redshifts called Wavelet Z Photometric (WaZP) applied to DES first year (Y1A1) data. The results are compared to…
Dark Energy Survey Year 1 Results: Constraining Baryonic Physics in the Universe
Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum +74
Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the f…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances and Weak Lensing
DES Collaboration, Tim Abbott, Michel Aguena +129
We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear…
Tomographic galaxy clustering with the Subaru Hyper Suprime-Cam first year public data release
Andrina Nicola, David Alonso, Javier Sánchez +12
We analyze the clustering of galaxies in the first public data release of the HSC Subaru Strategic Program. Despite the relatively small footprints of the observed fields, the data…
