The Cosmic Microwave Background

open access: yes, 2013
The Cosmic Microwave Background (CMB) is one of the pillars on which the Big Bang theory relies. High-quality maps of this radiation strongly constrain the history of the Universe and its content. Such maps require accurate and sensitive measurements of tiny random features on a strong uniform background.

Revisiting the A L Lensing Anomaly in Planck 2018 Temperature Data

open access: yesThe 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.

Testing Gaussianity, Homogeneity, and Isotropy with the Cosmic Microwave Background

open access: yesAdvances in Astronomy, 2010
We review the basic hypotheses which motivate the statistical framework used to analyze the cosmic microwave background, and how that framework can be enlarged as we relax those hypotheses.

The Cosmic Microwave Background and $$H_0$$

open access: yes
The cosmic microwave background (CMB) offers a unique window into the early universe, providing insights into cosmological parameters like the Hubble constant. Recent precise measurements of the CMB by experiments like Planck seem to point to a lower value for the Hubble constant compared to some other measurements like those from Type Ia supernovae ...
