Correcting correlation functions for redshift-dependent interloper contamination

Daniel J. Farrow, Ariel G. Sánchez, Robin Ciardullo +14

The construction of catalogues of a particular type of galaxy can be complicated by interlopers contaminating the sample. In spectroscopic galaxy surveys this can be due to the mis…

Testing one-loop galaxy bias: cosmological constraints from the power spectrum

Andrea Pezzotta, Martin Crocce, Alexander Eggemeier +2

We investigate the impact of different assumptions in the modeling of one-loop galaxy bias on the recovery of cosmological parameters, as a follow up of the analysis done in the fi…

Testing one-loop galaxy bias: joint analysis of power spectrum and bispectrum

Alexander Eggemeier, Román Scoccimarro, Robert E. Smith +3

We present a joint likelihood analysis of the real-space power spectrum and bispectrum measured from a variety of halo and galaxy mock catalogs. A novel aspect of this work is the…

Eternal solutions for a reaction-diffusion equation with weighted reaction

Razvan Gabriel Iagar, Ariel Sánchez

We prove existence and uniqueness of \emph{eternal solutions} in self-similar form growing up in time with exponential rate for the weighted reaction-diffusion equation $$ \partial…

Redshift-space distortions with split densities

Enrique Paillas, Yan-Chuan Cai, Nelson Padilla +1

Accurate modelling of redshift-space distortions (RSD) is challenging in the non-linear regime for two-point statistics e.g. the two-point correlation function (2PCF). We take a di…

MEDUSA: Minkowski functionals estimated from Delaunay tessellations of the three-dimensional large-scale structure

Martha Lippich, Ariel G. Sánchez

Minkowski functionals (MFs) are a set of statistics that characterise the geometry and topology of the cosmic density field and contain complementary information to the standard tw…
