Extending evolution mapping to massive neutrinos with COMET
A. Pezzotta, A. Eggemeier, G. Gambardella +7
We introduce an extension of the evolution mapping framework to cosmological models that include massive neutrinos. The original evolution mapping framework exploits a degeneracy i…
Beyond CDM constraints from the full shape clustering measurements from BOSS and eBOSS
Agne Semenaite, Ariel G. Sánchez, Andrea Pezzotta +7
We analyse the full shape of anisotropic clustering measurements from the extended Baryon Oscillation Spectroscopic survey (eBOSS) quasar sample together with the combined galaxy s…
Thermal Casimir effect in Gödel-type universes
A. F. Santos, Faqir C. Khanna
In this paper, a massless scalar field coupled to gravity is considered. Then the Casimir effect at finite temperature is calculated. Such development is carried out in the Thermo…
COMET: Clustering Observables Modelled by Emulated perturbation Theory
Alexander Eggemeier, Benjamin Camacho-Quevedo, Andrea Pezzotta +3
In this paper we present COMET, a Gaussian process emulator of the galaxy power spectrum multipoles in redshift-space. The model predictions are based on one-loop perturbation theo…
The cosmic shallows I: interaction of CMB photons in extended galaxy halos
Heliana E. Luparello, Ezequiel F. Boero, Marcelo Lares +2
We report and analyse the presence of foregrounds in the cosmic microwave background (CMB) radiation associated to extended galactic halos. Using the cross correlation of Planck an…
Blow-up patterns for a reaction-diffusion equation with weighted reaction in general dimension
Razvan Gabriel Iagar, Marta Latorre, Ariel Sánchez
We classify all the blow-up solutions in self-similar form to the following reaction-diffusion equation posed for , wit…
A special self-similar solution and existence of global solutions for a reaction-diffusion equation with Hardy potential
Razvan Gabriel Iagar, Ariel Sánchez
Existence and uniqueness of a specific self-similar solution is established for the following reaction-diffusion equation with Hardy singular potential $$ \partial_tu=Δu^m+|x|^{-2}…
Self-similar shrinking of supports and non-extinction for a nonlinear diffusion equation with spatially inhomogeneous strong absorption
Razvan Gabriel Iagar, Philippe Laurençot, Ariel Sánchez
We study the dynamics of the following porous medium equation with strong absorption posed for , with $m…
Self-similar solutions preventing finite time blow-up for reaction-diffusion equations with singular potential
Razvan Gabriel Iagar, Ana Isabel Muñoz, Ariel Sánchez
We prove existence and uniqueness of a global in time self-similar solution growing up as for the following reaction-diffusion equation with a singular potential $$ u_…
Cosmological implications of the full shape of anisotropic clustering measurements in BOSS and eBOSS
Agne Semenaite, Ariel G. Sánchez, Andrea Pezzotta +10
We present the analysis of the full shape of anisotropic clustering measurement from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample together with the co…
Redshift-space effects in voids and their impact on cosmological tests. Part II: the void-galaxy cross-correlation function
Carlos M. Correa, Dante J. Paz, Nelson D. Padilla +3
This is the second part of a thorough investigation of the redshift-space effects that affect void properties and the impact they have on cosmological tests. Here, we focus on the…
