62. DESI Part 1: Overview of the DESI survey and clustering measurments from DR1&DR2

Antoine Rocher (EPFL)

12/06/2025, 10:00

talk

The Dark Energy Spectroscopic Instrument (DESI) collaboration is conducting a five-year redshift survey of over 40 million galaxies. By targeting four different galaxy tracers, bright galaxies, luminous red galaxies, emission line galaxies and quasars across a large redshift range 0.1<z<3.5, DESI is designed to measure the expansion history of the Universe using Baryon Acoustic Oscillations...

63. DESI Part 2: Cosmological Implication of DR1&DR2 measurements

Large-scale structure

talk

The Dark Energy Spectroscopic Instrument (DESI) is conducting a five-year spectroscopic survey of 40 million galaxies and quasars, designed to map the cosmic expansion history and the growth of large-scale structure across the redshift range 0.1<z<3.5. Over the past year, the collaboration has released measurements of the baryon acoustic oscillation (BAO) scale from galaxies, quasars, and the...

35. Applications of Effective Field Theory in cosmology

Anton Chudaykin (University of Geneva)

Large-scale structure

talk

I will discuss the applications of the Effective Field Theory (EFT) in cosmology.

I will review the main concepts of the EFT of Large-Scale Structure, a theoretical framework that provides a systematic analytic description of cosmological observables on large scales. I will present a general perturbative model for a tracer of matter that depends on the line-of-sight selection effects, and...

45. Cosmology at small scales: combining probes with the baryonification method

Aurel Schneider (University of Zurich)

Large-scale structure

talk

Baryonic feedback processes significantly impact weak-lensing observations at small scales, introducing uncertainties and potential biases in cosmological parameter estimates. These challenges can be mitigated by combining weak-lensing data with complementary observations, such as X-ray and Sunyaev-Zeldovich (SZ) effect measurements. In this talk, I will introduce a new baryonification method...
