The High-Redshift Supernova Search -- Evidence for a Positive Cosmological Constant
Bruno Leibundgut, Gertrud Contardo, Patrick Woudt +1
A new component of the Universe which leads to an accelerated cosmic expansion is found from the measurements of distances to high-redshift type Ia supernovae. We describe the meth…
A Deep Optical Luminosity Function of NGC 6712 with the VLT: Evidence for Severe Tidal Disruption
Guido De Marchi, Bruno Leibundgut, Francesco Paresce +1
The VLT on Cerro Paranal was used to observe four fields located at 2.3' from the center of the Galactic globular cluster NGC 6712 in the V and R bands. The resulting color-magnitu…
Type Ia Supernovae and q0
B. Leibundgut
Type Ia Supernovae hold great promise to measure the cosmic deceleration. The diversity observed among these explosions, however, complicates their ability to measure cosmological…
