Supermassive black holes in the Sbc spiral galaxies NGC 3310, NGC 4303 and NGC 4258
Guia Pastorini, Alessandro Marconi, Alessandro Capetti +12
We present new Space Telescope Imaging Spectrograph (STIS) observations of three spiral galaxies, NGC 4303, NGC 3310 and NGC 4258. The bright optical emission lines H $6564…
Nuclear Properties of Nearby Spiral Galaxies from Hubble Space Telescope NICMOS imaging and STIS Spectroscopy
M. A. Hughes, D. Axon, J. Atkinson +16
We investigate the central regions of 23 spiral galaxies using archival NICMOS imaging and STIS spectroscopy. The sample is taken from our program to determine the masses of centra…
Supermassive black hole mass measurements for NGC 1300 and NGC 2748 based on HST emission-line gas kinematics
J. W. Atkinson, J. L. Collett, A. Marconi +18
We present Space Telescope Imaging Spectrograph emission-line spectra of the central regions of the spiral galaxies NGC 1300 and NGC 2748. From the derived kinematics of the nuclea…
Is there really a Black Hole at the center of NGC 4041? - Constraints from gas kinematics
A. Marconi, D. J. Axon, A. Capetti +16
We present HST/STIS spectra of the Sbc spiral galaxy NGC 4041 which were used to map the velocity field of the gas in its nuclear region. We detect the presence of a compact (r~0.4…
The black hole mass vs bulge mass relationship in spiral galaxies
A. Marconi, D. Axon, J. Atkinson +15
We describe an on-going HST program aimed at determining the relationship between the nuclear black hole mass and bulge mass in spiral galaxies. We have selected a volume limited s…
