Fast Lightcones for Combined Cosmological Probes
Raphael Sgier, Janis Fluri, Jörg Herbel +4
The combination of different cosmological probes offers stringent tests of the CDM model and enhanced control of systematics. For this purpose, we present an extension of the li…
Cosmological Forecast for non-Gaussian Statistics in large-scale weak Lensing Surveys
Dominik Zürcher, Janis Fluri, Raphael Sgier +2
Cosmic shear data contains a large amount of cosmological information encapsulated in the non-Gaussian features of the weak lensing mass maps. This information can be extracted usi…
Predicting Cosmological Observables with PyCosmo
F. Tarsitano, U. Schmitt, A. Refregier +7
Current and upcoming cosmological experiments open a new era of precision cosmology, thus demanding accurate theoretical predictions for cosmological observables. Because of the co…
Emulation of cosmological mass maps with conditional generative adversarial networks
Nathanaël Perraudin, Sandro Marcon, Aurelien Lucchi +1
Weak gravitational lensing mass maps play a crucial role in understanding the evolution of structures in the universe and our ability to constrain cosmological models. The predicti…
Measurement of the B-band Galaxy Luminosity Function with Approximate Bayesian Computation
Luca Tortorelli, Martina Fagioli, Jörg Herbel +3
The galaxy Luminosity Function (LF) is a key observable for galaxy formation, evolution studies and for cosmology. In this work, we propose a novel technique to forward model wide-…
