Constraining cosmological parameters using density split lensing and the conditional stellar mass function
Pierre A. Burger, Darshak A. Patel, Michael J. Hudson
In this work, we develop a simulation-based model to predict the excess surface mass density (ESD) depending on the local density environment. Using a conditional stellar mass func…

Cosmological parameters from the joint analysis of Density Split and Second Order Statistics: an Emulator based on the Halo Occupation Distribution
Pierre A. Burger, Enrique Paillas, Michael J. Hudson
In this work, we develop a simulation-based model to predict the density split (DSS) and second-order shear and clustering statistics. A simulation-based model has the potential to…
