Scattered Nuclear Continuum and Broad H-alpha in Cygnus A

, 1997
We have discovered scattered broad Balmer emission lines in the spectrum of Cygnus A, using the Keck II telescope. Broad H-alpha appears in polarized flux from components on either side of the nucleus, and to a lesser extent in the nucleus.

The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation [PDF]

, 2008
We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N).

Progressive supranuclear palsy: new concepts

Arquivos de Neuro-Psiquiatria, 2010
Progressive supranuclear palsy (PSP) is a distinctive form of neurodegenerative disease which affects the brainstem and basal ganglia. Patients present supranuclear ophthalmoplegia, postural instability and mild dementia.

Cross sections of $\alpha$-induced reactions for targets with masses $A \approx 20-50$ at low energies [PDF]

, 2015
A simple reduction scheme using so-called reduced energies $E_{\rm{red}}$ and reduced cross sections $\sigma_{\rm{red}}$ allows the comparison of heavy-ion induced reaction cross sections for a broad range of masses of projectile and target and over a ...

The Apparent Host Galaxy of PKS 1413+135: HST, ASCA and VLBA Observations [PDF]

, 2002
PKS 1413+135 (z=0.24671) is one of very few radio-loud AGN with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to heavy absorption but have been unable to place tight limits on the absorber or its ...
