The supermassive black hole in Centaurus A: a benchmark for gas kinematical measurements
A. Marconi, G. Pastorini, F. Pacini +5
We present new HST/STIS observations of Centaurus A. [SIII] 9533A was used to study the kinematics in the nuclear region with a 0.1" spatial resolution. The STIS data and the VLT/I…
Integral Field Spectroscopy of 23 Spiral Bulges
D. Batcheldor, D. Axon, D. Merritt +7
We have obtained Integral Field Spectroscopy for 23 spiral bulges using INTEGRAL on the William Herschel Telescope and SPIRAL on the Anglo-Australian Telescope. This is the first 2…
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…
Spectroscopy of the near-nuclear regions of Cygnus A: estimating the mass of the supermassive black hole
C. Tadhunter, A. Marconi, D. Axon +3
We use a combination of high spatial resolution optical and near-IR spectroscopic data to make a detailed study of the kinematics of the NLR gas in the near-nuclear regions of the…
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…
