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 at the level. Here we show for the first time t…
Evidence for a sign change of the ISW effect in the very recent universe? hot voids and cold overdensities at
Frode K. Hansen, Diego Garcia Lambas, Andrés N. Ruiz +2
We find a significant CMB temperature excess in the direction of local underdensities within . By contrast, less than of simulated CMB maps show a similarly signifi…
Revisiting the CMB homogeneity scale: low multipoles removal effect and extragalactic foreground masking
Xiaoyun Shao, Facundo Toscano, Diego Garcia Lambas +5
The Cosmic Microwave Background (CMB) reaches homogeneity at relatively modest angular scales compared to the expectation of the standard CDM model revealing an important challe…
Quasar Pairs as Large--Scale Structure tracers
Martín G. Richarte, Facundo Toscano, Diego G. Lambas +3
Quasars are effective tracers of the large-scale distribution of galaxies at high redshift thanks to their high luminosity and dedicated surveys. Previous studies have shown that q…
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 level previous studies reporting Cosmic Microwave Background (CMB) temperatures being significantly lower around nearby spiral galaxies than expected in th…
Are CMB derived cosmological parameters affected by foregrounds associated to nearby galaxies?
Facundo Toscano, Frode K. Hansen, Diego Garcia Lambas +3
We perform cosmological parameters estimation on Planck Cosmic Microwave Background (CMB) maps masking the recently discovered foreground related to nearby spiral galaxies. In addi…
The CMB Cold Spot as predicted by foregrounds around nearby galaxies
Diego Garcia Lambas, Frode K. Hansen, Facundo Toscano +2
The non-Gaussian Cold Spot (CS) surrounded by its hot ring is one of the most striking features of the CMB. It has been speculated that either new physics or ISW effect induced by…
A CMB lensing analysis of the extended mass distribution of clusters
Facundo Toscano, Heliana Luparello, Elizabeth Johana Gonzalez +1
The aim of this work is to study the anisotropic weak lensing signal associated with the mass distribution of massive clusters of galaxies using the Cosmic Microwave Background (CM…
