PSR J1740-3052 - a pulsar with a massive companion
I. H. Stairs, R. N. Manchester, A. G. Lyne +14
We report on the discovery of a binary pulsar, PSR J1740-3052, during the Parkes multibeam survey. Timing observations of the 570-ms pulsar at Jodrell Bank and Parkes show that it…
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…
ALFA & 3D: integral field spectroscopy with adaptive optics
R. Davies, M. Kasper, N. Thatte +4
One of the most important techniques for astrophysics with adaptive optics is the ability to do spectroscopy at diffraction limited scales. The extreme difficulty of positioning 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…
