Time Dilation in Type Ia Supernova Spectra at High Redshift
S. Blondin, T. M. Davis, K. Krisciunas +29
We present multiepoch spectra of 13 high-redshift Type Ia supernovae (SNe Ia) drawn from the literature, the ESSENCE and SNLS projects, and our own separate dedicated program on th…
High resolution spectroscopy of the line emission from the inner circumstellar ring of SN 1987A and its hot spots
Per Groeningsson, Claes Fransson, Peter Lundqvist +8
We discuss high resolution VLT/UVES observations (FWHM ~ 6 km/s) from October 2002 (day ~5700 past explosion) of the shock interaction of SN 1987A and its circumstellar ring. A neb…
Infrared Integral Field Spectroscopy of SN 1987A
Karina Kjaer, Bruno Leibundgut, Claes Fransson +3
SN 1987A in the Large Magellanic Cloud is close enough for a study of the very late time evolution of a supernova and its transition to a supernova remnant. Nearly two decades afte…
Observational Constraints on the Nature of the Dark Energy: First Cosmological Results from the ESSENCE Supernova Survey
W. M. Wood-Vasey, G. Miknaitis, C. W. Stubbs +34
We present constraints on the dark energy equation-of-state parameter, w=P/(rho c^2), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE supernova survey. We derive a set of con…
Inward Bound: Studying the Galactic Centre with NAOS/CONICA
T. Ott, R. Schoedel, R. Genzel +25
We report on the first results obtained using adaptive optics measurements of the Galactic Centre done with NAOS/CONICA.
Discovery of a faint Field Methane Brown Dwarf from ES0 NTT and VLT observations
J. G. Cuby, P. Saracco, A. F. M. Moorwood +4
We report the discovery of an isolated brown dwarf with similar properties to the binary object Gliese 229B and to the newly discovered field brown dwarf SDSS 1624+00. Although exh…
