Model Predictive Scoring Shows Specific BAO Observations (not SNIa) Drives Tension
Tanveer Karim, Joshua S. Speagle, Renée Hložek
The recent analyses of DESI DR2 BAO, Planck CMB and various Supernovae datasets have shown preferences for evolving dark energy at various levels of significance, under frequentist…
Measuring using DESI Legacy Imaging Surveys Emission-Line Galaxies and Planck CMB Lensing and the Impact of Dust on Parameter Inference
Tanveer Karim, Sukhdeep Singh, Mehdi Rezaie +39
Measuring the growth of structure is a powerful probe for studying the dark sector, especially in light of the tension between primary CMB anisotropy and low-redshift surveys…
Learning Reionization History from Quasars with Simulation-Based Inference
Huanqing Chen, Joshua Speagle, Keir K. Rogers
Understanding the entire history of the ionization state of the intergalactic medium (IGM) is at the frontier of astrophysics and cosmology. A promising method to achieve this is b…

Galaxy-Galaxy Lensing in HSC: Validation Tests and the Impact of Heterogeneous Spectroscopic Training Sets
Joshua S. Speagle, Alexie Leauthaud, Song Huang +9
Although photometric redshifts (photo-z's) are crucial ingredients for current and upcoming large-scale surveys, the high-quality spectroscopic redshifts currently available to tra…
Evidence for the Cross-correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam
