Cosmological and astrophysical aspects of 21 cm intensity mapping surveys
a talk by Camila Paiva Novaes (Instituto Nacional de Pesquisas Espaciais - INPE/Brasil) - Remote
Abstract:
"Intensity mapping (IM) of the redshifted 21 cm line emission from neutral hydrogen is an efficient technique for surveying the large-scale structure of the Universe. In this talk, I discuss cosmological and astrophysical aspects of 21 cm IM, addressing instrumental limitations that affect clustering measurements, the role of cross-correlations between radio and photometric galaxy surveys, and the extraction of cosmological constraints from summary statistics through machine learning. These topics are explored in the context of current and upcoming radio telescopes, illustrating how 21 cm IM can contribute to testing fundamental assumptions of the standard cosmological model and constraining its parameters."
Short-Bio:
I am a researcher at the Astrophysics Division of INPE, Brazil. I hold a Ph.D. in Astrophysics from INPE. My research focuses on statistical analyses of cosmological data and simulations, including the CMB, the 21 cm signal, and other large-scale structure tracers.
