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…
Exploring Statistical Isotropy in Planck Data Release 4: Angular Clustering and Cosmological Parameter Variations Across the Sky
C. Gimeno-Amo, F. K. Hansen, E. Martínez-González +2
The origin of small deviations from statistical isotropy in the Cosmic Microwave Background (CMB) - the so-called CMB anomalies - remains an open question in modern cosmology. In t…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
A Joint Analysis of BICEP2/Keck Array and Planck Data
BICEP2/Keck, Planck Collaborations, : +276
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg patch of sky centered on…
Planck intermediate results. XXVIII. Interstellar gas and dust in the Chamaeleon clouds as seen by Fermi LAT and Planck
Planck, Fermi Collaborations, : +197
Shortened abstract: Observations of the nearby Chamaeleon clouds in gamma rays with the Fermi Large Area Telescope and in thermal dust emission with Planck and IRAS have been used…
Cosmological Applications of the Gaussian Kinematic Formula
Yabebal Fantaye, Frode Hansen, Davide Maino +1
The Gaussian Kinematic Formula (GKF, see Adler and Taylor (2007,2011)) is an extremely powerful tool allowing for explicit analytic predictions of expected values of Minkowski func…
