Anomalous self-similar solutions of exponential type for the subcritical fast diffusion equation with weighted reaction
Razvan Gabriel Iagar, Ariel Sánchez
We prove existence and uniqueness of the branch of the so-called \emph{anomalous eternal solutions} in exponential self-similar form for the subcritical fast-diffusion equation wit…
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…
Separate variable blow-up patterns for a reaction-diffusion equation with critical weighted reaction
Razvan Gabriel Iagar, Ariel Sánchez
We study the separate variable blow-up patterns associated to the following second order reaction-diffusion equation: posed for $x\in\mathbb{R}^N…
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…
