Shutting down or powering up a (U)LIRG? Merger components in distinctly different evolutionary states in IRAS 19115-2124 (The Bird)
P. Väisänen, J. Reunanen, J. Kotilainen +4
We present new SINFONI near-infrared integral field unit (IFU) spectroscopy and SALT optical long-slit spectroscopy characterising the history of a nearby merging luminous infrared…
Origin of the wide-angle hot H2 in DG Tauri: New insight from SINFONI spectro-imaging
Vanessa Agra-Amboage, S. Cabrit, C. Dougados +3
We wish to test the origins proposed for the extended hot H2 at 2000K around the atomic jet from the T Tauri star DGTau, in order to constrain the wide-angle wind structure and the…
Near-infrared spectroscopy of stellar populations in nearby spiral galaxies
J. K. Kotilainen, T. Hyvonen, J. Reunanen +1
We present high spatial resolution, medium spectral resolution near-infrared (NIR) H- and K-band long-slit spectroscopy for a sample of 29 nearby (z < 0.01) inactive spiral galaxie…
Central regions of LIRGs: rings, hidden starbursts, Supernovae and star clusters
Petri Vaisanen, Andres Escala, Erkki Kankare +7
We study star formation (SF) in very active environments, in luminous IR galaxies, which are often interacting. A variety of phenomena are detected, such as central starbursts, cir…
The nuclear PAH emission of merger system NGC 1614: rings within rings
Petri Vaisanen, Vinesh Rajpaul, Albert A. Zijlstra +2
It is important to understand the interplay between nuclear star-formation and nuclear activity when studying the evolution of gas rich galaxy mergers. We present here new spatiall…
Sub-arcsecond [FeII] spectro-imaging of the DG Tau jet: Periodic bubbles and a dusty disk wind?
V. Agra-Amboage, C. Dougados, S. Cabrit +1
We present SINFONI/VLT observations of the DG Tauri jet in the [FeII] lines with 0.15" angular resolution and R=3000 spectral resolution. We observe an onion-like velocity structur…
