    Extensions of Virasoro group and Virasoro algebra by modules of tensor-densities on $S^1$
    We classify non-trivial (non-central) extensions of the group $Diff^+(S^1)$ of all diffeomorphisms of the circle preserving its orientation and of the Lie...

    Extinction as a tool to find distances to X-ray sources
    Finding distances in astronomy is notoriously difficult. With accurate optical spectroscopy, both the distance to and extinction (reddening) of normal stars can...

    Extinction corrections in ground based infrared spectrometry
    Calculations of atmospheric transmission through the M (5 microns) atmospheric window, at a resolution of 10 to the 3rd power are presented for sites at the...

    Extinction over the Canarian observatories: the limited influence of Saharan dust
    We present a study of the atmospheric extinction over the observatories of the Canary Islands, based mainly on photometric measurements of the V-band extinction...

    Extracting rotation rates on 27-d TESS-like light curves downgrading Kepler data
    Evolution of surface magnetic features in the star, such as stellar spots or faculae, can leave a signature in the lightcurves. These features allow us to study...

    Extragalactic Radio Astronomy from an Armchair: Continuum Spectral Shapes of 150 Faint Sources
    We have used all available radio-source surveys to construct the continuum spectra for sources in an area of 5 by 10 degrees near the North Ecliptic Pole (NEP)...
