Probing IGM large-scale flows: warps in galaxies at shells of voids
M. Lopez-Corredoira, E. Florido, J. Betancort-Rijo +5
CONTEXT. Hydrodynamical cosmological simulations predict flows of the intergalactic medium along the radial vector of the voids, approximately in the direction of the infall of mat…
Discovery of a galactic wind in the central region of M100
J. Jiménez-Vicente, A. Castillo-Morales, E. Mediavilla +1
We report the discovery of a galactic wind in the central region of the galaxy M100. This result is based on a careful 2D spectroscopic study performed on observations made with th…
On the metallicity dependence of the 24micron luminosity as a star formation tracer
M. Relano, U. Lisenfeld, P. G. Perez-Gonzalez +2
We investigate the use of the rest-frame 24microns luminosity as an indicator of the star formation rate (SFR) in galaxies with different metallicities by comparing it to the (exti…
Truncated stellar discs in the near infrared. II. Statistical properties and interpretation
E. Florido, E. Battaner, A. Guijarro +2
The results obtained in paper I are used to study possible relationships between the truncation radius of stellar discs in the NIR and structural parameters of the galaxies. The NI…
Truncated stellar disks in the near infrared. I. Observations
E. Florido, E. Battaner, A. Guijarro +2
We present NIR surface photometry of 11 edge-on galaxies obtained in the course of a long term project aimed at analysing the occurrence and type of the truncation of the outer dis…
Asymmetrical structure of ionization and kinematics in the Seyfert galaxy NGC 5033
E. Mediavilla, A. Guijarro, A. Castillo-Morales +5
We present integral field spectroscopy of NGC 5033, a low luminosity Seyfert galaxy. The observations were made with INTEGRAL, a fiber based system operating at the WHT. The intens…
A catalog of warps in spiral and lenticular galaxies in the Southern hemisphere
M. L. Sanchez-Saavedra, E. Battaner, A. Guijarro +2
A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sanchez-Saavedra et al., with 42 galaxies in the northern hemisphere,…
Warps and correlations with intrinsic parameters of galaxies in the visible and radio
N. Castro-Rodriguez, M. Lopez-Corredoira, M. L. Sanchez-Saavedra +1
From a comparison of the different parameters of warped galaxies in the radio, and especially in the visible, we find that: a) No large galaxy (large mass or radius) has been found…
The truncation of stellar discs: the magnetic hypothesis
E. Battaner, E. Florido, J. Jimenez-Vicente
We propose a hypothesis of the truncation of stellar discs based on the magnetic model of the rotation curve of spiral galaxies. Once the disc had formed and acquired its present s…
Statistics of galaxy warps in the HDF North and South
V. Reshetnikov, E. Battaner, F. Combes +1
We present a statistical study of the presence of galaxy warps in the Hubble deep fields. Among a complete sample of 45 edge-on galaxies above a diameter of 1.''3, we find 5 galaxi…
Near infrared observations of the truncation of stellar disks
Estrella Florido, Eduardo Battaner, Ana Guijarro +2
We present a first study of truncation of the stellar disks of spiral galaxies in the near infrared. Observations of NGC4013, NGC4217, NGC6504 and NGC5981 were made with the CAIN N…
Magnetic Fields are not ignorable in the dynamics of disks
E. Battaner, E. Florido, A. Guijarro
Magnetic fields are considered to be dominant when , being the magnetic energy density and the rotation energy density, for a co…
Magnetic fields and the large-scale structure
E. Battaner, E. Florido
The large-scale structure of the Universe has been observed to be characterized by long filaments, forming polyhedra, with a remarkable 100-200 Mpc periodicity, suggesting a regula…
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…
Geometrical parametrization of warps for edge-on galaxies
J. Jimenez-Vicente, C. Porcel, M. L. Sanchez-Saavedra +1
We propose new parameters to describe the geometry of a warped disc when viewed edge-on, a global warp parameter , and a family of three parameters , and that describ…
The radial scale length of the Milky Way
C. Porcel, F. Garzon, J. Jimenez-Vicente +1
The radial scale length of the exponential component of the disc of the Milky Way has been determined in the near infrared. We have used the TMGS (Two Micron Galactic Survey) datab…
