Scientific paper

A new technique using near ultraviolet imaging to detect transient sources was implemented with the Space Telescope Imaging Spectrograph (STIS) in the core of M87, an area of this galaxy left unexplored by previous studies due to crowding. With HST's unique resolution and sensitivity we detected thirteen novae candidates within less than one kiloparsec from the nucleus. Our findings indicate that the frequency of nova events in the core of M87 is considerably higher than in the rest of the galaxy. This effect may be due to mass segregation of white dwarfs or to the presence of the nearby AGN. These novae candidates do not show a conspicuous orientation or alignment with respect to the prominent jet of M87 as previously thought.
