Multiprobe Cosmology from the Abundance of SPT Clusters and DES Galaxy Clustering and Weak Lensing

S. Bocquet, S. Grandis, E. Krause +216

Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints…

Dark Energy Survey Year 3: Blue Shear

J. McCullough, A. Amon, E. Legnani +115

Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, sta…

Improving Galaxy Cluster Selection with the Outskirt Stellar Mass of Galaxies

Matthew Kwiecien, Tesla Jeltema, Alexie Leauthaud +53

The number density and redshift evolution of optically selected galaxy clusters offer an independent measurement of the amplitude of matter fluctuations, . However, recent res…

Enhancing weak lensing redshift distribution characterization by optimizing the Dark Energy Survey Self-Organizing Map Photo-z method

A. Campos, B. Yin, S. Dodelson +111

Characterization of the redshift distribution of ensembles of galaxies is pivotal for large scale structure cosmological studies. In this work, we focus on improving the Self-Organ…

Weak Gravitational Lensing around Low Surface Brightness Galaxies in the DES Year 3 Data

N. Chicoine, J. Prat, G. Zacharegkas +102

We present galaxy-galaxy lensing measurements using a sample of low surface brightness galaxies (LSBGs) drawn from the Dark Energy Survey Year 3 (Y3) data as lenses. LSBGs are diff…

Dark Energy Survey Year 3 Results: Cosmology from galaxy clustering and galaxy-galaxy lensing in harmonic space

L. Faga, F. Andrade-Oliveira, H. Camacho +100

We present the joint tomographic analysis of galaxy-galaxy lensing and galaxy clustering in harmonic space, using galaxy catalogues from the first three years of observations by th…

Dark Energy Survey Year 3 results: simulation-based cosmological inference with wavelet harmonics, scattering transforms, and moments of weak lensing mass maps II. Cosmological results

M. Gatti, G. Campailla, N. Jeffrey +99

We present a simulation-based cosmological analysis using a combination of Gaussian and non-Gaussian statistics of the weak lensing mass (convergence) maps from the first three yea…

Weak lensing combined with the kinetic Sunyaev Zel'dovich effect: A study of baryonic feedback

L. Bigwood, A. Amon, A. Schneider +122

Extracting precise cosmology from weak lensing surveys requires modelling the non-linear matter power spectrum, which is suppressed at small scales due to baryonic feedback process…

Dark Energy Survey Year 3 results: likelihood-free, simulation-based CDM inference with neural compression of weak-lensing map statistics

N. Jeffrey, L. Whiteway, M. Gatti +88

We present simulation-based cosmological CDM inference using Dark Energy Survey Year 3 weak-lensing maps, via neural data compression of weak-lensing map summary statistics: pow…

The SRG/eROSITA All-Sky Survey: Dark Energy Survey Year 3 Weak Gravitational Lensing by eRASS1 selected Galaxy Clusters

S. Grandis, V. Ghirardini, S. Bocquet +119

Number counts of galaxy clusters across redshift are a powerful cosmological probe, if a precise and accurate reconstruction of the underlying mass distribution is performed -- a c…
