Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
Could 1I/'Oumuamua be macroscopic dark matter?
David Cyncynates, Emanuela Dimastrogiovanni, Saurabh Kumar +2
1I/'Oumuamua, formerly known as A/2017 U1, is a sizable body currently passing through the solar system. It is generally considered to be a rocky asteroid-like object that came fro…
Possible Signatures of Inflationary Particle Content: Spin-2 Fields
Matteo Biagetti, Emanuela Dimastrogiovanni, Matteo Fasiello
We study the imprints of a massive spin-2 field on inflationary observables, and in particular on the breaking of consistency relations. In this setup, the minimal inflationary fie…
Probing the scale dependence of non-Gaussianity with spectral distortions of the cosmic microwave background
Razieh Emami, Emanuela Dimastrogiovanni, Jens Chluba +1
Many inflation models predict that primordial density perturbations have a nonzero three-point correlation function, or bispectrum in Fourier space. Of the several possibilities fo…
Reheating predictions in single field inflation
Jessica L. Cook, Emanuela Dimastrogiovanni, Damien A. Easson +1
Reheating is a transition era after the end of inflation, during which the inflaton is converted into the particles that populate the Universe at later times. No direct cosmologica…
