Fabry-Perot observations of the ionized gas in NGC 3938
J. Jimenez-Vicente, E. Battaner, M. Rozas +2
The nearly face-on spiral galaxy NGC 3938 has been observed in the line with the TAURUS II Fabry-Perot interferometer at the William Herschel Telescope in order to study the…
Magnetic fields and rotation of spiral galaxies
E. Battaner, H. Lesch, E. Florido
We present a simplified model in which we suggest that two important galactic problems -the magnetic field configuration at large scales and the flat rotation curve- may be simulta…
The egg-carton Universe
E. Battaner, E. Florido
The distribution of superclusters in the Local Supercluster neighbourhood presents such a remarkable periodicity that some kind of network must fit the observed large scale structu…
The fractal octahedron network of the large scale structure
E. Battaner
In a previous article, we have proposed that the large scale structure network generated by large scale magnetic fields could consist of a network of octahedra only contacting at t…
The truncation of stellar discs. A theoretical model
E. Battaner, E. Florido, J. Jimenez-Vicente
The truncation of stellar discs is not abrupt but characterized by a continuous distancing from the exponential profile. There exists a truncation curve, , ending at a trunca…
