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…
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 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(…
