The underlying ethos of Open Access is that the public should have the right to free access to the published results of all publicly funded academic and...
Is the jet variability reflected in the BLR emission from FSRQ's?
We present an spectroscopic study of a sample of bright gamma-ray blazars. Our dataset includes spectra of a sample of about 10 targets, all of them Flat...
Is the Mn I 539.4 nm Variation with Activity Explained?
The photospheric Mn I 539.4 nm line in the solar spectrum shows unusual variability with the solar cycle in that its depth decreases with increasing activity...
Is the supersonic turbulence observed in HII regions sustained by the presence of magnetic fields?
We describe a set of Hα emission line profiles from populations of H II regions in nearby spiral galaxies. These are characterized by a strong Gaussian central...
Is there a carbon-depleted population in the trans-neptunian belt?
Recent results suggest that there is a group of trans-Neptunian objects (TNOs), 2003 EL61 being the biggest member, with similar dynamical and physical...
