Improved Planck constraints on axion-like early dark energy as a resolution of the Hubble tension
George Efstathiou, Erik Rosenberg, Vivian Poulin
Axion-like early dark energy (EDE) as an extension to CDM has been proposed as a possible solution to the 'Hubble tension'. We revisit this model using a new cosmic microwave ba…
CMB power spectra and cosmological parameters from Planck PR4 with CamSpec
Erik Rosenberg, Steven Gratton, George Efstathiou
We present angular power spectra and cosmological parameter constraints derived from the Planck PR4 (NPIPE) maps of the Cosmic Microwave Background. NPIPE, released by the Planck C…
Mitigating the effects of undersampling in weak lensing shear estimation with metacalibration
Arun Kannawadi, Erik Rosenberg, Henk Hoekstra
Metacalibration is a state-of-the-art technique for measuring weak gravitational lensing shear from well-sampled galaxy images. We investigate the accuracy of shear measured with m…
