Two-dimensional metallicity distribution of the ionized gas in NGC 628 and NGC 6946
Bernabé Cedrés, Jordi Cepa, Ángel Bongiovanni +3
We present here two H II region catalogues with azimuthal resolution for the two grand design galaxies NGC 628 and NGC 6946. With the help of these catalogues, we study several pro…
Extraplanar emission in isolated edge-on late-type galaxies.II. The H kinematics
Minerva M. Sardaneta, Philippe Amram, Roberto Rampazzo +3
Isolated galaxies are rare yet invaluable for studying secular evolution, as their physical properties can remain largely unaffected by external influences for several billion year…
Numerical Study of Bar Suppression in Galaxy Models Due to Disc Heating
Alejandro López Gómez, Ruslan Gabbasov, Isaura Luisa Fuentes-Carrera
The process of bar formation, evolution and destruction is still a controversial topic regarding galaxy dynamics. Numerical simulations show that these phenomena strongly depend on…
A Natural Explanation of the VPOS from Multistate Scalar Field Dark Matter
Tula Bernal, Tonatiuh Matos, Leonardo San. -Hernandez
Observations with the Gaia satellite have confirmed that the satellite galaxies of the Milky Way are not distributed as homogeneously as expected. The same occurs in galaxies such…
Extraplanar emission in isolated edge-on late-type galaxies. I. The H distribution versus to the old and young stellar discs
Minerva M. Sardaneta, Philippe Amram, Roberto Rampazzo +4
Isolated galaxies are the ideal reference sample to study the galaxy structure minimising potential environmental effects. We selected a complete sample of 14 nearby, late-type, hi…
Chemical Abundances of a Sample of Oxygen-dominated Galaxies
B. E. Miranda-Pérez, A. M. Hidalgo-Gámez
We spectroscopically analyzed a sample of 85 Sloan Digital Sky Survey compact, oxygen-dominated galaxies located at redshift , selected because of their large equ…
