SPEAKER: Noah Sailer (UC Berkeley)- Title: Accurate cosmology from CMB lensing and galaxy surveys
April 7, 2023 @ 12:00 pm - 1:00 pm
This is an In-Person [HYBRID] Event
Date: April 7, 2023
Time: 12:00- 1:00 pm
Location: Sessler Conference Room- 50A-5132
Speaker: Noah Sailer (UC Berkeley)
Title: Accurate cosmology from CMB lensing and galaxy surveys
Abstract:
Joint analyses of CMB lensing and spectroscopically-calibrated galaxies have the ability to measure the evolution of matter fluctuations out to high redshifts without the complications of photometric redshift uncertainties and intrinsic alignments. These measurements are rapidly becoming one of the more powerful tools in a cosmologist’s toolkit, enabling precise (and accurate) inference of cosmological parameters and potential deviations from ΛCDM. While cross-correlations are typically more robust against systematic effects, correlated systematics arising from (extra)galactic foreground contamination and masking induce significant biases if not properly accounted for. I will discuss progress towards mitigating these effects, the implementation of these methods in an ongoing cross-correlation analysis of DESI luminous red galaxies and CMB lensing from ACT, and the prospects of future analyses with Stage-V spectroscopy and CMB-S4.
