I will briefly review my research interest on Low Surface Brightness Galaxies (LSBGs). I will show the latest results from our survey for LSBGs with the Sloan Digital Sky Survey (SDSS) data.

The quasar spectral energy distribution (SED) in the UV is characterized by a sharp break near 1000 A. The SED (in Fnu) of quasars can be described by a broken powerlaw. Telfer et al.

The solar coronal heating is one of the most important problem to be solved for the astrophysics. Although it is widely accepted that the magnetic filed emerging from the solar surface plays an essential role for the coronal heating, the detailed mechanism is totally unknown.

Definitivamente las nubes interestelares no son esféricas (ni cúbicas!). Su complejidad es difícil de modelar basados en cualquier figura geométrica simple.

Los sistemas "virializados" de partículas que interactúan sólo gravitatoriamente tienen perfiles de densidad y velocidad bien definidos que se extienden hasta varios radios viriales.
The end products of the life of the first stars in the Galaxy are preserved in the most metal-poor stars we see today. A Large Programme of high-resolution spectroscopy at the ESO VLT has enabled us to study the compositon of such stars in unprecedented detail.

The Nordic Optical Telescope (NOT) has now been in successful operation on La Palma for 15 years. Great changes have taken place in Nordic and European astronomy during that time. Notably, ESO has commissioned the VLT, to which most Nordic astronomers now have access.

It is generally believed that Lorentz invariance is an exact symmetry of Nature. Together with the equivalence principle, local Lorentz invariance is one of the assumptions underpinning General Relativity.

La formulación de los modelos de síntesis evolutiva fue planteada a mediados de los años 60 para analizar las poblaciones estelares en sistemas no resueltos en un esquema acorde a la instrumentación de esa época. Dicha formulación no se ha replanteado en los últimos 30 años.

We begin by showing that a collapsing dust cloud with a central homogeneous core must have a faint atmosphere in the Brane-World, unlike the four-dimensional General Relativistic case, in which a pure vacuum exterior is allowed.

Las manchas han sido estudiadas intensamente desde la invención del telescopio. En ellas, el campo magnético y los movimientos del plasma están íntimamente ligados, produciendo estructuras filamentosas muy pequeñas (100-200 km).

We report on IFS observations of the nuclear regions of 3C 120, using INTEGRAL at the 4.2m WHT telescope. We propose new methods to deblend the spectra of the nucleus and the host galaxy based in 2D decompositions, and to extract the spectra of the substructures in complex systems.
