Description
I will present the most recent results of our group related to the discovery of a systematic effect on the CMB temperature maps when we consider the nearest local structures in the Universe. Being statistically significant results compared to simulations from the Planck Collaboration, I will show how nearby galaxies and filaments have a negative temperature profile while local voids have positive temperatures. Furthermore, I will explore the possibility of obtaining different cosmological parameters taking into account this new extragalactic foreground.
