The des view of the Eridanus supervoid and the CMB cold spot
(2022-02-01)
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground structure at low redshift, the Eridanus ...
Spectral optical monitoring of 3C 390.3 in 1995-2007: I. Light curves and flux variation in the continuum and broad lines
(2010)
Context. We present the results of the long-term (1995-2007) spectral monitoring of the broad-line radio galaxy 3C 390.3, a well known AGN with double-peaked broad emission lines, usually assumed to be emitted from an ...
Spectral optical monitoring of 3C 390.3 in 1995-2007: I. Light curves and flux variation in the continuum and broad lines
(2005)
A spectral model of nonlinear internal gravity waves (IGW) in a shallow sea with smooth horizontal heterogeneities is analyzed. It is shown that self-action produces harmonics of carrier frequency in the wave field and ...
CP-strong problem and U(1)' non-universal symmetry
(Departamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-07-19)
We present a non-universal U (1)X extension and an additional global anomala Peccei-Quinn (PQ) symmetry to the standard model (SM). The scheme proposed allow us to distinguish among fermion families without introducing ...
