High Accuracy Near-infrared Imaging Polarimetry with NICMOS
D. Batcheldor, G. Schneider, D. C. Hines +5
The findings of a nine orbit calibration plan carried out during HST Cycle 15, to fully determine the NICMOS camera 2 (2.0 micron) polarization calibration to high accuracy, are re…
High Accuracy Imaging Polarimetry with NICMOS
D. Batcheldor, G. Schneider, D. C. Hines +5
The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2-1.5%. To better quantify an…
The M-Sigma Project
D. Batcheldor
There is an intimate link between supermassive black hole (SMBH) mass (M) and the stellar velocity dispersion (sigma) of the host bulge. This has a fundamental impact on our unders…
The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design
David Carter, Paul Goudfrooij, Bahram Mobasher +34
We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey…
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…
Dominant Nuclear Outflow Driving Mechanisms in Powerful Radio Galaxies
Dan Batcheldor, Clive Tadhunter, Joanna Holt +4
In order to identify the dominant nuclear outflow mechanisms in Active Galactic Nuclei, we have undertaken deep, high resolution observations of two compact radio sources (PKS 1549…
