The Physical Content of Long Tensor Modes in Cosmology
Nicola Bartolo, Giovanni Battista Carollo, Sabino Matarrese +2
We analyze the physical content of squeezed bispectra involving long-wavelength tensor perturbations, showing that these modes cannot be gauged away, except for the exact (unphysic…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Primordial Non-Gaussianity in Supersolid Inflation
Marco Celoria, Denis Comelli, Luigi Pilo +1
We study primordial non-gaussianity in supersolid inflation. The dynamics of supersolid is formulated in terms of an effective field theory based on four scalar fields with a shift…
Resilience of long modes in cosmological observables
Sabino Matarrese, Luigi Pilo, Rocco Rollo
By a careful implementation of gauge transformations involving long-wavelength modes, we show that a variety of effects involving squeezed bispectrum configurations, for which one…
