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 chall…
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…
Cosmic filaments confirm unexplained CMB temperature decrements in two independent redshift ranges
Juan Ignacio DomÃnguez 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…
The connection between surface brightness and satellite systems for central galaxies through Illustris TNG
Silvio Rodriguez, Yamila Yaryura, Jose A. Benavides +7
We analyse different properties of central low-surface-brightness galaxies (LSBGs) and their satellite systems using the simulation Illustris TNG-100, in order to deepen our unders…
Quasar Pairs as Large--Scale Structure tracers
MartÃn 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…
