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…
A simple model of magnetically induced warps
E. Battaner, J. Jimenez-Vicente
Assuming the magnetic hypothesis for the formation of warps, we deduce a very simple formula for the warp curve in an idealized scenario. According to this formula the warp rises a…
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…
