Self-calibration of weak lensing cosmic shear biases
Giuseppe Congedo, Andy Taylor
In order to reach the required performance of Stage-III and IV weak lensing surveys, cosmic shear measurements have to rely on external simulations to calibrate residual biases. Ov…
Future prospects on testing extensions to CDM through the weak lensing of gravitational waves
Charlie T. Mpetha, Giuseppe Congedo, Andy Taylor
With planned space-based and 3rd generation ground-based gravitational wave detectors (LISA, Einstein Telescope, Cosmic Explorer), and proposed DeciHz detectors (DECIGO, Big Bang O…
Testing Quadratic Maximum Likelihood estimators for forthcoming Stage-IV weak lensing surveys
Alessandro Maraio, Alex Hall, Andy Taylor
Headline constraints on cosmological parameters from current weak lensing surveys are derived from two-point statistics that are known to be statistically sub-optimal, even in the…
Non-Gaussian likelihood of weak lensing power spectra
Alex Hall, Andy Taylor
The power spectrum of weak lensing fluctuations has a non-Gaussian distribution due to its quadratic nature. On small scales the Central Limit Theorem acts to Gaussianize this dist…
A minimal self tuning model to solve the cosmological constant problem
Arnaz Khan, Andy Taylor
The expansion of the Universe is observed to be accelerating, with the simplest solution being a classical cosmological constant. However, this receives contributions from the quan…
Euclid: impact of nonlinear prescriptions on cosmological parameter estimation from weak lensing cosmic shear
M. Martinelli, I. Tutusaus, M. Archidiacono +91
Upcoming surveys will map the growth of large-scale structure with unprecented precision, improving our understanding of the dark sector of the Universe. Unfortunately, much of the…
