Examining Uranus' zeta ring in Voyager 2 Wide-Angle-Camera Observations: Quantifying the Ring's Structure in 1986 and its Modifications prior to the Year 2007
M. M. Hedman, I. Regan, T. Becker +3
The zeta ring is the innermost component of the Uranian ring system. It is of scientific interest because its morphology changed significantly between the Voyager 2 encounter in 19…
PMAS: The Potsdam Multi Aperture Spectrophotometer. II. The Wide Integral Field Unit PPak
Andreas Kelz, Marc A. W. Verheijen, Martin M. Roth +6
PPak is a new fiber-based Integral Field Unit (IFU), developed at the Astrophysical Institute Potsdam, implemented as a module into the existing PMAS spectrograph. The purpose of P…
PMAS, the Potsdam Multi-Aperture Spectrophotometer. I. Design, Manufacture, and Performance
M. M. Roth, A. Kelz, T. Fechner +12
We describe the design, manufacture, commissioning, and performance of PMAS, the Potsdam Multi-Aperture Spectrophotometer. PMAS is a dedicated integral field spectrophotometer, opt…
Abundances and kinematics of a candidate sub-damped Lyman-alpha galaxy toward PHL 1226
L. Christensen, R. E. Schulte-Ladbeck, S. F. Sanchez +5
The spectrum of the quasar PHL 1226 is known to have a strong Mg II and sub-damped Lyman-alpha (sub-DLA) absorption line system with N(HI)=(5+/-2)*10^19 cm^-2 at z=0.1602. Using in…
Integral field observations of DLA galaxies
L. Christensen, S. F. Sanchez, K. Jahnke +4
We report preliminary results from a targeted investigation on quasars containing damped Lyman-alpha absorption (DLA) lines as well strong metal absorption lines, carried out with…
3D Spectrophotometry of Planetary Nebulae in the Bulge of M31
M. M. Roth, T. Becker, A. Kelz +1
We introduce crowded field integral field (3D) spectrophotometry as a useful technique for the study of resolved stellar populations in nearby galaxies. As a methodological test, w…
