Planck Dust Polarization Power Spectra Are Consistent with Strongly Supersonic Turbulence

The Astrophysical Journal
The polarization of the cosmic microwave background is rich in information but obscured by foreground emission from the Milky Way’s interstellar medium (ISM). To uncover relationships between the underlying turbulent ISM and the foreground power spectra,

Does the Correlation between 2MRS Galaxies and the CMB Indicate an Unmodeled CMB Foreground?

The Astrophysical Journal
We revisit the claimed detection of a new cosmic microwave background (CMB) foreground based on the correlation between low-redshift Two Micron All Sky Survey Redshift Survey (2MRS) galaxies and CMB temperature maps from the Planck and Wilkinson ...

ƒ(R) Gravity, Relic Coherent Gravitons and Optical Chaos

Galaxies, 2014
We discuss the production of massive relic coherent gravitons in a particular class of ƒ(R) gravity, which arises from string theory, and their possible imprint in the Cosmic Microwave Background.

Standard Clock in primordial density perturbations and cosmic microwave background

Physics Letters B, 2014
Standard Clocks in the primordial epoch leave a special type of features in the primordial perturbations, which can be used to directly measure the scale factor of the primordial universe as a function of time a(t), thus discriminating between inflation ...

Revisiting the A L Lensing Anomaly in Planck 2018 Temperature Data

The Astrophysical Journal
We revisit the lensing anomaly in the Planck 2018 temperature (TT) data and examine its robustness to frequency selection and additional sky masking. Our main findings are as follows.
