Maximising information from weak lensing galaxy surveys
Alessandro Maraio
Weak lensing galaxy surveys are currently undergoing a dramatic revolution as the dawn of the Stage-IV surveys are upon us. Hence, ensuring that our analysis methods are as accurat…
Mitigating baryon feedback bias in cosmic shear through a theoretical error covariance in the matter power spectrum
Alessandro Maraio, Alex Hall, Andy Taylor
Forthcoming cosmic shear surveys will make precise measurements of the matter density field down to very small scales, scales which are dominated by baryon feedback. The modelling…
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-Gaussianity in D3-brane inflation
Kareem Marzouk, Alessandro Maraio, David Seery
We update predictions for observables in the "delicate" D3/anti-D3 inflationary model on the conifold. We use a full CMB likelihood calculation to assess goodness-of-fit, which is…
