DOI: 10.1088/1475-7516/2018/10/002
Abstract: We reconsider a recently proposed warm G-inflation scenario in which the Galileon scalar field concurrently dissipates its kinetic energy as the radiation fluid throughout inflation and the universe smoothly enters into a radiation dominated era… read more here.

Abstract: We conduct an analysis of the Planck 2015 data that is complete in reionization observables from the large angle polarization $E$-mode spectrum in the redshift range $6lzl30$. Based on 5 principal components, all of which… read more here.

DOI: 10.1103/physrevd.96.083526
Abstract: We explore the relationship between features in the Planck 2015 temperature and polarization data, shifts in the cosmological parameters, and features from inflation. Residuals in the temperature data at low multipole $\ell$, which are responsible… read more here.

DOI: 10.1103/physrevd.98.043518
Abstract: Features during inflation and reionization leave corresponding features in the temperature and polarization power spectra that could potentially explain anomalies in the Planck 2015 data but require a joint analysis to disentangle. We study the… read more here.

DOI: 10.1103/physrevd.98.063514
Abstract: We study the relationship between signatures of high redshift ionization in large-angle CMB polarization power spectra and features in the Planck 2015 data. Using a principal component (PC) ionization basis that is complete to the… read more here.
