Relativistic effects on LSS spectrum and bispectrum

Abstract: I will discuss the Large Scale Structure spectrum and bispectrum in a relativistic framework. To first order, a relativistic description includes terms beyond the Kaiser approximation (doppler effects and galaxy evolution), gravitational potentials and integrated terms (cosmic magnification, integrated Sachs-Wolfe and Shapiro time-delay). These terms are currently neglected, but they might play a role in future surveys which probe larger scales. I will show how they can be isolated by correlating different probes, or by using the so-called multi-tracer technique. Moreover, some relativistic effects could give a non-negligible contribution to the LSS observables, hence, by neglecting them, the analysis may lead to biased cosmological parameters.

Upcoming Events: Nuclear Science and Technology Symposium – NST2016
The Finnish Nuclear Society (FNS) organizes the Nuclear Science and
Technology Symposium – NST2016 on November 2-3, 2016 in Helsinki. The
symposium gathers together research, industry and authority
representatives from Finland and abroad for scientific talks and
industry presentations. The FNS 50-year anniversary dinner and lectures
for the general public are held in connection with the symposium. For
details see the webpage http://www.ats-fns.fi/en/nst2016.
