Mining the unrevealed population of red-nugget relics in disk galaxies
Do galaxies that quenched at early epochs remain passive since then or do they rejuvenate, experiencing further episodes of star formation? We apply a structure...
Photometry of the X-ray transient XTE J1859+226, obtained during outburst, showed at least 3 minioutbursts. During the second one, the source exhibited a 0.3...
The different evolutionary paths followed by the galaxies along their lives are expected to leave an imprint in their sizes. Nevertheless, observationally the...
