Single-Field Consistency Relations of Large Scale Structure. Part III: Test of the Equivalence Principle

Paolo Creminelli, Jérôme Gleyzes, Lam Hui +2

The recently derived consistency relations for Large Scale Structure do not hold if the Equivalence Principle (EP) is violated. We show it explicitly in a toy model with two fluids…

Investigating the presence of 500 um submillimeter excess emission in local star forming galaxies

Allison Kirkpatrick, Daniela Calzetti, Maud Galametz +10

Submillimeter excess emission has been reported at 500 microns in a handful of local galaxies, and previous studies suggest that it could be correlated with metal abundance. We inv…
