Optical and Infrared Spectroscopy of SN 1999ee and SN 1999ex
Mario Hamuy, Jose Maza, Philip A. Pinto +17
We report optical and infrared spectroscopic observations of the Type Ia SN 1999ee and the Type Ib/c SN 1999ex, both of which were hosted by the galaxy IC 5179. For SN 1999ee we ob…
Cosmic alignment towards the radio Einstein ring PKS 1830-211 ?
F. Courbin, G. Meylan, J. P. Kneib +1
Optical and near-IR Hubble Space Telescope and Gemini-North adaptive optics images, further improved through deconvolution, are used to explore the gravitationally lensed radio sou…
The X-ray, Optical and Infrared Counterpart to GRB 980703
P. M. Vreeswijk, T. J. Galama, A. Owens +36
We report on X-ray, optical and infrared follow-up observations of GRB 980703. We detect a previously unknown X-ray source in the GRB error box; assuming a power law decline we fin…
The redshift of the gravitationally lensed radio source PKS1830-211
C. Lidman, F. Courbin, G. Meylan +3
We report on the spectroscopic identification and the long awaited redshift measurement of the heavily obscured, gravitationally lensed radio source PKS 1830-211, which was first o…
