Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
Observational Constraints on the Primordial Curvature Power Spectrum
Razieh Emami, George Smoot
CMB observations provide a precise measurement of the primordial power spectrum on large scales, corresponding to wavenumbers Mpc < k < 0.1 Mpc, [1-8]. Lumi…
Stable solutions of inflation driven by vector fields
Razieh Emami, Shinji Mukohyama, Ryo Namba +1
Many models of inflation driven by vector fields alone have been known to be plagued by pathological behaviors, namely ghost and/or gradient instabilities. In this work, we seek a…
Cosmological tests of an axiverse-inspired quintessence field
Razieh Emami, Daniel Grin, Josef Pradler +2
Inspired by the string axiverse idea, it has been suggested that the recent transition from decelerated to accelerated cosmic expansion is driven by an axion-like quintessence fiel…
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…
