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…
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…
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 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 t…
