Spatially resolved spectroscopy of planetary nebulae and their halos I. Five galactic disk objects
Christer Sandin, Detlef Schönberner, Martin M. Roth +3
Strong mass loss off stars at the tip of the asymptotic giant branch (AGB) profoundly affects properties of these stars and their surroundings, including the subsequent planetary n…
VLT-VIMOS integral field spectroscopy of luminous and ultraluminous infrared galaxies. I. The sample and first results
Santiago Arribas, Luis Colina, Ana Monreal-Ibero +3
(Ultra)Luminous Infrared Galaxies [(U)LIRGs] are much more numerous at cosmological distances than locally, and are likely precursors of elliptical galaxies. Our goal is to carry o…
Search for Tidal Dwarf Galaxies Candidates in a Sample of Ultraluminous Infrared Galaxies
A. Monreal-Ibero, L. Colina, S. Arribas +1
(ABRIDGED) Star-forming small galaxies made out of collisional debris have been found in a variety of merging systems. So far only a few of them are known in ULIRGs although they s…
New observations of the halo radial temperature structure in NGC7662
C. Sandin, D. Schoenberner, M. M. Roth +4
We report on our studies of the physical structure of the planetary nebula (PN) NGC7662. Using (3D) Integral Field Spectroscopy we have been able to measure the electron temperatur…
3D-Spectroscopy of extragalactic planetary nebulae as diagnostic probes for galaxy evolution
Andreas Kelz, Ana Monreal-Ibero, Martin M. Roth +3
In addition to study extragalactic stellar populations in their integrated light, the detailed analysis of individual resolved objects has become feasible, mainly for luminous gian…
LINER-like Extended Nebulae in ULIRGs: Shocks Generated by Merger Induced Flows
A. Monreal-Ibero, S. Arribas, L. Colina
In this work we studied the two-dimensional ionization structure of the circumnuclear and extranuclear regions in a sample of six low-z Ultraluminous Infrared Galaxies using Integr…
Integral Field Spectroscopy of Faint Haloes of Planetary Nebulae
A. Monreal-Ibero, M. M. Roth, D. Schoenberner +2
We present the first integral field spectroscopy observations of the two planetary nebulae NGC3242 and NGC4361 with the VIMOS instrument attached to VLT-UT3. By co-adding a large n…
