K-band Spectroscopy of Clusters in NGC 4038/4039

Sabine Mengel, Matthew D. Lehnert, Niranjan Thatte +2

Integral field spectroscopy in the K-band (1.9-2.4um) was performed on four IR-bright star clusters and the two nuclei in NGC 4038/4039 (``The Antennae''). Two of the clusters are…

VLT-ISAAC near-IR Spectroscopy of ISO selected Hubble Deep Field South Galaxies

D. Rigopoulou, A. Franceschini, H. Aussel +9

We report the results of near-infrared VLT-ISAAC spectroscopy of a sample of 12 galaxies at z = 0.4-1.4, drawn from the ISOCAM survey of the Hubble Deep Field South. We find that t…

Massive star formation and evolution in starburst galaxies: mid-infrared spectroscopy with ISO-SWS

M. D. Thornley, N. M. Forster-Schreiber, D. Lutz +4

We present new ISO-SWS data for a sample of 27 starburst galaxies, and with these data examine the issues of formation and evolution of the most massive stars in starburst galaxies…

Searching for AGN signatures in Mid-IR Spectra: The case of NGC1068

O. Laurent, I. F. Mirabel, V. Charmandaris +3

We present mid-IR observations of the prototypical Seyfert 2 galaxy NGC 1068 obtained with ISOCAM between 5 and 16micron. The proximity of this galaxy coupled with the spectro-imag…

The European Large Area ISO Survey I: Goals, Definition and Observation

Seb Oliver, the ELAIS consortium

We describe the European Large Area ISO Survey (ELAIS). ELAIS was the largest single Open Time project conducted by ISO, mapping an area of 12 square degrees at 15mu with ISO-CAM a…

Stellar Dynamics and the implications on the merger evolution in NGC6240

M. Tecza, R. Genzel, L. J. Tacconi +3

We report near-infrared integral field spectroscopy of the luminous merging galaxy NGC 6240. Stellar velocities show that the two K-band peaks separated by 1.6arcsec are the centra…

NIR Spectroscopy with the VLT of a sample of ISO selected Hubble Deep Field South Galaxies

D. Rigopoulou, A. Franceschini, R. Genzel +6

A new population of faint galaxies characterized by an extremely high rate of evolution with redshift up to z~1.5 has recently been discovered by ISO. These sources are likely to c…
