Aims:We investigate the statistical properties of the extreme events of the solar cycle as measured by the sunspot number. Methods: The recent advances in the...
Extreme-ultraviolet (EUV) observables of simulated plasmoid-mediated reconnection in the solar corona
Context. Understanding the role of magnetic reconnection in the heating and dynamics of the solar atmosphere requires detailed observational data of any...
Far- and mid-infrared spectroscopy of complex organic matter of astrochemical interest: coal, heavy petroleum fractions and asphaltenes
The coexistence of a large variety of molecular species (i.e. aromatic, cycloaliphatic and aliphatic) in several astrophysical environments suggests that...
Far-infrared spectroscopy of proteinogenic and other less common amino acids
Far-infrared spectroscopy is a powerful tool complementing the potential of mid-infrared spectroscopy for the search and identification of organic molecules in...
Fast Inversion of Spectral Lines Using Principal Components Analysis. II. Inversion of Real Stokes Data
The principal components analysis (PCA) technique is used to develop an extremely fast and stable Stokes inversion code, suitable for application to large data...
Feature Extraction Techniques for the Analysis of Spectral Polarization Profiles
This paper introduces a novel feature extraction technique for the analysis of spectral line Stokes profiles. The procedure is based on the use of an...
Featureless transmission spectra of 12 giant exoplanets observed by GTC/OSIRIS
Context. Exoplanet atmospheres are the key to understanding the nature of exoplanets. To this end, transit spectrophotometry provides us opportunities to...
Field-level Lyman-α forest modeling in redshift space via augmented nonlocal Fluctuating Gunn-Peterson Approximation
Context. Devising fast and accurate methods of predicting the Lyman-α forest at the field level, avoiding the computational burden of running large-volume...
Fifteen years of XMM-Newton and Chandra monitoring of Sgr A★: evidence for a recent increase in the bright flaring rate
We present a study of the X-ray flaring activity of Sgr A⋆ during all the 150 XMM-Newton and Chandra observations pointed at the Milky Way centre over the last...
