CMB experiments have contributed powerful constraints on the fundamental physics and astrophysics of the Universe. Current CMB experiments, such as the Simons Observatory, are poised to extend this progress even further. However, CMB experiments still have a wealth of information to offer beyond near-term facilities, including probing the properties of dark matter, inflation, and light relic...

The gravitational lensing of the Cosmic Microwave Background (CMB) provides a powerful and robust probe of the projected matter distribution across cosmic time, offering unique sensitivity to the growth of large-scale structure, cosmic expansion, and fundamental physics such as the sum of neutrino masses. As cosmology enters a high-precision era, CMB lensing has become a cornerstone observable...

The past decade has seen the rise of high-precision cosmological observations accompanied by emerging tensions among various datasets when interpreted within the standard cosmological model (ΛCDM). Recently, baryonic acoustic oscillation (BAO) measurements from the Dark Energy Spectroscopic Instrument (DESI) have shown a mild discrepancy with current cosmic microwave background (CMB) data....

106. Robust Cosmology at z > 1: Unlocking ELG Cross-Correlations with the CMB and CIB

Tanveer Karim (University of Toronto)

Stage-IV surveys like DESI increasingly rely on z > 1 Emission-Line Galaxies (ELGs) for cross-correlation analyses, capitalizing on their overlap with CMB secondaries such as the CMB lensing and Cosmic Infrared Background (CIB) kernels. However, unlocking their full cosmological potential requires navigating complex observational systematics and non-trivial galaxy-halo connections. In this...

73. Leveraging simulations to study the millimetre sky

Oral Talk

Observations of the millimetre sky contain a wealth of signals from across the history of the Universe. Current observations have reached the sensitivity where we able to make precision measurements of the signals sourced by the large-scale structure of the Universe, known as CMB secondary anisotropies. Optimally analyzing many of these signals is challenging as CMB secondaries are highly...
