Modeling Redshift Uncertainties in Roman Weak Lensing Cosmology
Diogo H. F. de Souza, Boyan Yin, Tim Eifler +7
Cosmological constraints using weak gravitational lensing measurements from the Roman Space Telescope will require a powerful method for modelling uncertainties in the galaxy redsh…
Accurate modeling for 32pt analyses in Roman and Rubin: a study of model approximations
Junzhou Zhang, Chihway Chang, Jiachuan Xu +6
One of the pillars of modern cosmology is the use of galaxy imaging surveys to extract information from the large-scale structure. In recent surveys, this measurement is typically…
Raising the reionization optical depth with inflationary CMB features
Tanisha Jhaveri, Wayne Hu, Vivian Miranda
Within the highly successful CDM paradigm established with cosmic microwave background (CMB) anisotropy measurements, the optical depth through reionization is the most un…
Towards the Two-Loop EFTofLSS in Galaxy Lensing Surveys
Evan Saraivanov, Henrique Rubira, Vivian Miranda +1
Extracting cosmological information from Stage IV weak lensing surveys requires non-linear modelling of the matter power spectrum that is accurate across a broad range of scales an…
Constraining baryonic feedback and cosmology from DES Y3 and Planck PR4 62pt data. I. CDM models
Jiachuan Xu, Tim Eifler, Elisabeth Krause +3
We combine weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing, and their cross-correlations (so-called 62pt) to constrain cosmology and baryonic fee…
Fisher Forecasts for Cosmological Yields from pt Analysis of the Roman Space Telescope High Latitude Imaging Survey
Kaili Cao, David H. Weinberg, Vivian Miranda +4
The High Latitude Imaging Survey (HLIS) of NASA's Nancy Grace Roman Space Telescope will provide powerful tests of cosmological models through sensitive measurements of cosmic shea…
