Confronting cosmic shear astrophysical uncertainties: DES Year 3 revisited
Leah Bigwood, Jamie McCullough, Jared Siegel +19
Cosmology from weak gravitational lensing has been limited by astrophysical uncertainties in baryonic feedback and intrinsic alignments. By calibrating these effects using external…
The Power Spectrum of the Thermal Sunyaev-Zeldovich Effect
George Efstathiou, Fiona McCarthy
The power spectrum of unresolved thermal Sunyaev-Zeldovich (tSZ) clusters is extremely sensitive to the amplitude of the matter fluctuations. This paper present an analysis of the…
Evolving Dark Energy or Supernovae Systematics?
George Efstathiou
Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strong…
Challenges to the Lambda CDM Cosmology
George Efstathiou
Observations of the cosmic microwave backgroundradiation are described to remarkable accuracy by the six-parameterLambda CDM cosmology. However, the key ingredients of this model,…
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…
B-mode constraints from Planck low multipole polarisation data
Roger de Belsunce, Steven Gratton, George Efstathiou
We present constraints on primordial B modes from large angular scale cosmic microwave background polarisation anisotropies measured with the Planck satellite. To remove Galactic p…
