    Extensions and contractions of the Lie algebra of q-pseudodifferential symbols
    We construct cocycles on the Lie algebra of pseudo- and q-pseudodifferential symbols of one variable and on their close relatives: the sine-algebra and the...
  • Publication
    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...
  • Publication
    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...
