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…
Improved Tomographic Binning of 3x2pt Lens Samples: Neural Network Classifiers and Optimal Bin Assignments
Irene Moskowitz, Eric Gawiser, Abby Bault +4
Large imaging surveys, such as the Legacy Survey of Space and Time, rely on photometric redshifts and tomographic binning for 3x2pt analyses that combine galaxy clustering and weak…
A study of the hydrostatic mass bias dependence and evolution within The Three Hundred clusters
Giulia Gianfagna, Elena Rasia, Weiguang Cui +4
We use a set of about 300 simulated clusters from The Three Hundred Project to calculate their hydrostatic masses and evaluate the associated bias by comparing them with the true c…
Lagrangian displacement field estimators in cosmology
Atsuhisa Ota, Hee-Jong Seo, Shun Saito +1
The late-time nonlinear Lagrangian displacement field is highly correlated with the initial field, so reconstructing it could enable us to extract primordial cosmological informati…
Boundless baryons: how diffuse gas contributes to anisotropic tSZ signal around simulated Three Hundred clusters
Martine Lokken, Weiguang Cui, J. Richard Bond +4
Upcoming advances in galaxy surveys and cosmic microwave background data will enable measurements of the anisotropic distribution of diffuse gas in filaments and superclusters at r…
Almanac: Weak Lensing power spectra and map inference on the masked sphere
A. Loureiro, L. Whiteway, E. Sellentin +3
We present a field-based signal extraction of weak lensing from noisy observations on the curved and masked sky. We test the analysis on a simulated Euclid-like survey, using a Euc…
