Evidence for a sign change of the ISW effect in the very recent universe? hot voids and cold overdensities at z<0.03

Frode K. Hansen, Diego Garcia Lambas, Andrés N. Ruiz +2

We find a significant CMB temperature excess in the direction of local underdensities within z<0.03. By contrast, less than 0.2% of simulated CMB maps show a similarly signifi…

Cosmic filaments confirm unexplained CMB temperature decrements in two independent redshift ranges

Juan Ignacio Domínguez Feldman, Luis A. Pereyra, Frode K. Hansen +2

Recent papers have reported an unexplained cooling of CMB photons passing through galaxies in nearby cosmic filaments z<0.02 at the >5I¨ƒ level. Here we show for the first time…

A p<0.0001 detection of CMB cooling in galactic halos and its possible relation to dark matter

Frode K. Hansen, Diego Garcia Lambas, Heliana E. Luparello +2

We confirm at the 5.7I¨ƒ level previous studies reporting Cosmic Microwave Background (CMB) temperatures being significantly lower around nearby spiral galaxies than expected in t…
