This paper is the first in a set that analyses the covariance matrices of clustering statistics obtained from several approximate methods for gravitational...

We compare the measurements of the bispectrum and the estimate of its covariance obtained from a set of different methods for the efficient generation of...

We study the accuracy of several approximate methods for gravitational dynamics in terms of halo power spectrum multipoles and their estimated covariance matrix...

Using samples drawn from the Sloan Digital Sky Survey, we study for the first time the relation between large-scale environments (clusters, groups, and voids)...

This work is a study of the relationship between astronomy and landscape focused on the orientation of Christian churches of the three main Manorial (Señorío)...

We present the first comparison between the lifetime star formation histories (SFHs) of M31 and Milky Way (MW) satellites. Using the Advanced Camera for Surveys...

The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work, we investigate how active galactic...

Solar magnetic fields alter scattering polarization in spectral lines like Sr I at 4607 Å via the Hanle effect, making it a potential diagnostic for small-scale...

We present a large-scale combination of near-infrared (near-IR) interstellar polarization data from background starlight with polarized emission data at...
