Fast estimation of aperture-mass statistics I: aperture mass variance and an application to the CFHTLenS data
Lucas Porth, Robert E. Smith, Patrick Simon +2
We explore an alternative method to the usual shear correlation function approach for the estimation of aperture mass statistics in weak lensing survey data. Our approach builds on…
Cosmology constraints from shear peak statistics in Dark Energy Survey Science Verification data
T. Kacprzak, D. Kirk, O. Friedrich +81
Shear peak statistics has gained a lot of attention recently as a practical alternative to the two point statistics for constraining cosmological parameters. We perform a shear pea…
What is the optimal way to measure the galaxy power spectrum?
Robert E. Smith, Laura Marian
Measurements of the galaxy power spectrum contain a wealth of information about the Universe. Its optimal extraction is vital if we are to truly understand the micro-physical natur…
Towards optimal estimation of the galaxy power spectrum
Robert E. Smith, Laura Marian
The galaxy power spectrum encodes a wealth of information about cosmology and the matter fluctuations. Its unbiased and optimal estimation is therefore of great importance. In this…
An exploration of galaxy-galaxy lensing and galaxy clustering in the Millennium-XXL simulation
Laura Marian, Robert E. Smith, Raul E. Angulo
The combination of galaxy-galaxy lensing and galaxy clustering data has the potential to simultaneously constrain both the cosmological and galaxy formation models. In this paper w…
Toward optimal cluster power spectrum analysis
Robert E. Smith, Laura Marian
The power spectrum of galaxy clusters is an important probe of the cosmological model. In this paper we determine the optimal weighting scheme for maximizing the signal-to-noise ra…
