Testing the ΛCDM Cosmological Model with Forthcoming Measurements of the Cosmic Microwave Background with SPT-3G

The Astrophysical Journal
We forecast constraints on cosmological parameters enabled by three surveys conducted with SPT-3G, the third-generation camera on the South Pole Telescope.

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.

The Impact of Population III.1 Flash Reionization for Cosmic Microwave Background Polarization and Thomson Scattering Optical Depth

The Astrophysical Journal Letters
The Population III.1 theory for supermassive black hole (SMBH) formation predicts a very early ( z  ∼ 20–25) transient phase, the “Pop III.1 Flash,” of cosmic reionization powered by supermassive stars that are SMBH progenitors. The Universe then quickly

Combining cosmic microwave background datasets with consistent foreground modelling

Astronomy & Astrophysics
We present a joint cosmological analysis combining data from the Planck satellite, the Atacama Cosmology Telescope, and the South Pole Telescope. We construct a unified likelihood that reproduces the measured temperature and polarisation power spectra by
