The effects of seeing on the parameters of the Sèrsic profile are studied in an analytical form using a Gaussian point spread function. The surface brightness...

The effects of seeing on Sérsic r1/n profile parameters are extensively studied using a Moffat function. This analytical approximation to the point spread...

We determine the entire electrical current density vector in a geometrical three-dimensional volume of the inner penumbra of a sunspot from an inversion of...

The existence of systematic spectral-fit residuals in ROSAT PSPC spectra, and their dependence on time, is by now a well established fact. This paper describes...

The ability of any Machine Learning method to classify the spectra of galaxies depending on the properties of the stellar component rests on the information...

The inverse problem of extracting the stellar population content of galaxy spectra is analysed here from a basic standpoint based on information theory. By...

Context. While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and...

Even the most sensitive cosmic microwave background anisotropy experiments have signal-to-noise ratios

I present a simplified analytical model that simulates the evolution of the binary population in a dynamically evolving globular cluster. A number of...
