The variable UV central spike of NGC 4552
ASTR SOC P 117 (1997) 545-549
Abstract:
The nature of the UV-bright spike at the center of the otherwise normal galaxy NGC 4552 is investigated by means of both Hubble Space Telescope (HST) imaging (FOC) and spectroscopy (FOS). This central feature-which underwent a recent dramatic UV flare-provides a potential new tool for revealing the presence of massive black holes in normal galaxies. In particular the sub-arcsec FOS spectra of the nucleus suggest that NGC 4552 does harbor an object with mass M > 4 x 10(8) M. within the central 2 pc.AN ULTRAVIOLET FLARE AT THE CENTER OF THE ELLIPTIC GALAXY NGC4552
