Organised Randoms: Learning and correcting for systematic galaxy clustering patterns in KiDS using self-organising maps

no code implementations15 Dec 2020 Harry Johnston, Angus H. Wright, Benjamin Joachimi, Maciej Bilicki, Nora Elisa Chisari, Andrej Dvornik, Thomas Erben, Benjamin Giblin, Catherine Heymans, Hendrik Hildebrandt, Henk Hoekstra, Shahab Joudaki, Mohammadjavad Vakili

We then create `organised' randoms, i. e. random galaxy catalogues with spatially variable number densities, mimicking the learnt systematic density modes in the data.

The halo model as a versatile tool to predict intrinsic alignments

no code implementations5 Mar 2020 Maria Cristina Fortuna, Henk Hoekstra, Benjamin Joachimi, Harry Johnston, Nora Elisa Chisari, Christos Georgiou, Constance Mahony

In this paper, we use the halo model formalism to capture this diversity and examine its implications for Stage-III and Stage-IV cosmic shear surveys.

Wagoner

As a result, predictions for correlation functions of galaxy clustering, galaxy-galaxy lensing and cosmic shear are demonstrated to be within a fraction of the expected statistical uncertainty of the observables for the models and in the range of scales of interest to LSST.
