The Effective Field Theory of Large-Scale Structure (EFTofLSS) provides a powerful theoretical framework for understanding the distribution of matter and galaxies in the universe on cosmological scales. This course introduces the key developments in EFTofLSS, emphasizing its role in bridging theoretical physics with observational data from galaxy surveys.

Target audience: Master’s and PhD students in Cosmology, and last-year undergrad students with solid theoretical physics background.

There is no registration.

Lecturer:

Henrique Rubira (LMU/Cambridge)

Additional Information

Attention! Some participants in ICTP-SAIFR activities have received email from fake travel agencies asking for credit card information. All communication with participants will be made by ICTP-SAIFR staff using an e-mail “@ictp-saifr.org”. We will not send any mailings about accommodation that require a credit card number or any sort of deposit. Also, if you are staying at Hotel Intercity the Universe Paulista, please confirm with the Uber/Taxi driver that the hotel is located at Rua Pamplona 83 in Bela Vista (and not in Jardim Etelvina).

How to reach the Institute: The minicourse will be held at ICTP South American Institute, located at IFT-UNESP, which is across the street from a major bus and subway terminal (Terminal Barra Funda). The address which is closer to the entrance of the IFT-UNESP building is R. Jornalista Aloysio Biondi, 120 – Barra Funda, São Paulo. The easiest way to reach us is by subway or bus, please find instructions here.
