  • Publication
    On the lack of a simple relation between RE and mu-e for early-type galaxies
    The direct correlation between effective radius Re and corresponding surface brightness mu-e, found for early-type galaxies by Kormendy (1977) and later...
  • Publication
    On the lensed blazar B0218+357
    We present an optical spectrum (λλ4000-10 500) of the lensed blazar B0218+357 secured at the 10 m GTC and aimed to investigate and clarify the properties of...
  • Publication
    On the Magnetic Field of Off-limb Spicules
    Determining the magnetic field related to solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in...
  • Publication
    On the Magnetic Nature of an Exploding Granule as Revealed by Sunrise/IMaX
    We study the photospheric evolution of an exploding granule observed in the quiet Sun at high spatial (∼0"3) and temporal (31.5 s) resolution by the imaging...
  • Publication
    On the Magnetic Nature of Quiet-Sun Chromospheric Grains
    Ca II K grains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the...
  • Publication
    On the Magnetism and Dynamics of Prominence Legs Hosting Tornadoes
    Solar tornadoes are dark vertical filamentary structures observed in the extreme ultraviolet associated with prominence legs and filament barbs. Their true...
  • Publication
    On the mass of the compact object in GRO J0422+32
    We report the detection of the secondary star spectrum in the hard X-ray transient GRO J0422+32 during its lowest quiescent state. From the amplitude of the...
  • Publication
    On the mass of the neutron star in Cyg X-2
    We present new high-resolution spectroscopy of the low-mass X-ray binary Cyg X-2, which enables us to refine the orbital solution and rotational broadening of...
  • Publication
    On the masses and evolutionary status of the black hole binary GX 339-4: a twin system of XTE J1550-564?
    We apply the K-correction to the black hole low-mass X-ray binary (LMXB) GX 339-4 which implies MX >= 6Msolar by only assuming that the companion is more...
