Reviewing the observational evidence against long-lived spiral arms in galaxies
Eric E. Martinez-Garcia, Ivanio Puerari
We review Foyle et al. (2011) previous results, by applying a Fourier intensity phases method to a nine object sample of galaxies. It was found that two of the objects (NGC 628 and…
Signatures of long-lived spiral patterns
Eric E. Martinez-Garcia, Rosa A. Gonzalez-lopezlira
Azimuthal age/color gradients across spiral arms are a signature of long-lived spirals. From a sample of 19 normal (or weakly barred) spirals where we have previously found azimuth…
Slowly rotating gas-rich galaxies in modified Newtonian dynamics (MOND)
F. J. Sanchez-Salcedo, A. M. Hidalgo-Gamez, Eric E. Martinez-Garcia
We have carried out a search for gas-rich dwarf galaxies that have lower rotation velocities in their outskirts than MOdified Newtonian Dynamics (MOND) predicts, so that the amplit…
