On the ages of the stellar populations of galaxies at -7
Eric E. Martínez-García
Recent studies have reported a non evolution of galaxy ages at redshifts higher than 2.5, as well as galaxies older than the Universe. In this work, a sample of galaxies fr…
Colour jumps across the spiral arms of Hubble Ultra Deep Field galaxies
Eric E. Martínez-García, Rosa A. González-Lópezlira, Ivânio Puerari
We have measured, at various wavelengths, the spiral arm pitch angles of a sample of distant spiral galaxies from the Hubble Space Telescope eXtreme Deep Field (XDF). According to…
Mass content of UGC 6446 and UGC 7524 through HI rotation curves: deriving the stellar discs from stellar population synthesis models
P. Repetto, Eric E. Martinez-Garcia, M. Rosado +1
In this work we study the mass distribution of two irregular galaxies, UGC 6446 and UGC 7524, by means of HI rotation curves derived from high resolution HI velocity fields obtaine…
