نویسنده
چکیده
We present optical spectra of the Type Ic supernova 1994I in M51 and preliminary non-LTE analysis of the spectra. Our models are not inconsistent with the explosions of C+O cores of massive stars. While we find no direct evidence for helium in the optical spectra, our models cannot rule out small amounts of helium. More than 0.1 M⊙ of helium seems unlikely.

Optical spectra of SN1994W in NGC 4041 revealed the presence of a dense (Ne >10 8 cm circumstellar shell. An observation with the ROSAT HRI detected a source, with a luminosity of ∼8×10 ergs s, coincident with the position of SN1994W to within 1.4. The positional coincidence plus the optical evidence for a dense circumstellar shell support the identification of the X-ray source as SN1994W. Subj...

We describe our preliminary results on a search for high-redshift (z > 0.5) galaxy clusters using near-infrared photometry obtained with the Omega camera at the 3.5m telescope at Calar Alto.
