C. | American Astronomical Society | 2005-07-01Recent far-UV (FUV) and near-UV (NUV) observations of the nearby galaxy NGC 4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended UV disk reaching to 4 times the optical radius of the galaxy. The UV-to-optical color[...]texto impreso
Junais, ; Boissier, S. ; Epinat, B. ; Amram, P. ; Madore, B.F. ; Boselli, A. ; Koda, J. ; Gil de Paz, Armando ; Muñoz Mateos, J.C. ; Chemin, L. | EDP Sciencies | 2020-05-07Context. Malin 1 is the largest known low surface brightness (LSB) galaxy, the archetype of so-called giant LSB galaxies. The structure and origin of such galaxies are still poorly understood, especially because of the lack of high-resolution ki[...]texto impreso
