The Cosmological Correlation Dimension Beyond the Linear Regime: Analytical Approximation and Parameter Sensitivity
Miguel Aparicio Resco, Florencia A. Teppa Pannia
The correlation dimension () provides a scale-dependent characterization of the transition towards homogeneity and a complementary perspective on the clustering of large-scale…
J-PAS: Forecasting constraints on Neutrino Masses
Gabriel Rodrigues, Antonio J. Cuesta, Jailson Alcaniz +30
The large-scale structure survey J-PAS is taking data since October 2023. In this work, we present a forecast based on the Fisher matrix method to establish its sensitivity to the…
J-PAS and PFS surveys in the era of dark energy and neutrino mass measurements
Fuxing Qin, Yuting Wang, Gong-Bo Zhao +28
Fisher-matrix forecasts are presented for the cosmological surveys of the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) and the Subaru Prime Focus Sp…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
Modified gravity or imperfect dark matter: a model-independent discrimination
Miguel Aparicio Resco, Antonio L. Maroto
We analyze how to parametrize general modifications of the dark matter perturbations equations in a model-independent way. We prove that a general model with an imperfect and non-c…
The Fisher gAlaxy suRvey cOde ()
Miguel Aparicio Resco, Antonio L. Maroto
The Fisher gAlaxy suRvey cOde () is a new public Python code that computes the Fisher matrix for galaxy surveys observables. The observables considered are the linea…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
Testing for gravitational preferred directions with galaxy and lensing surveys
Miguel Aparicio Resco, Antonio L. Maroto
We analyze the sensitivity of galaxy and weak-lensing surveys to detect preferred directions in the gravitational interaction. We consider general theories of gravity involving add…
Parametrizing modified gravities with vector degrees of freedom: anisotropic growth and lensing
Miguel Aparicio Resco, Antonio L. Maroto
We consider the problem of parametrizing modified gravity theories that include an additional vector field in the sub-Hubble regime within the quasi-static approximation. We start…
Parametrizing growth in dark energy and modified gravity models
Miguel Aparicio Resco, Antonio L. Maroto
It is well-known that an extremely accurate parametrization of the growth function of matter density perturbations in CDM cosmology, with errors below , is given by $f(…
On neutron stars in f(R) theories: small radii, large masses and large energy emitted in a merger
Miguel Aparicio Resco, Alvaro de la Cruz-Dombriz, Felipe J. Llanes-Estrada +1
In the context of f(R) gravity theories, we show that the apparent mass of a neutron star as seen from an observer at infinity is numerically calculable but requires careful matchi…
