hello everyone i'm joseph corolla a postdoctoral researcher at university paris cycling today i'll be talking to you about three point gaussian streaming model for rxspace distortion this talk will be based on a recent work with cristiano porciani i will start the talk with a brief introduction to right space distortion in astronomy the third dimension is given by the redshift to an object however the observed redshift is affected by both the cosmological expansion and the peculiar velocity along the line of sight hence the three-dimensional maps of the universe we obtain are distorted to pictorially explain we here show a slice from the end body simulation we employed in this work on the left panel is information from real space or the unobserved reference frame and here clearly we can see some cosmic web elements high dense regions called as the clusters are denoted by orange points here while there are also features like the filaments running along this slice the under dense regions
