We present the Gallery of Planetary Nebula Spectra now available at http://oit.williams.edu/nebulae The website offers high-quality, moderate resolution (~7-10 A FWHM) spectra of 1…
Early and late time VLT spectroscopy of SN 2001el - progenitor constraints for a type Ia supernova
S. Mattila, P. Lundqvist, J. Sollerman +5
We present early time high-resolution (VLT/UVES) and late time low-resolution (VLT/FORS) optical spectra of the normal type Ia supernova, SN 2001el. The high-resolution spectra wer…
High velocity features in the spectra of the Type Ia SN 1999ee: a property of the explosion or evidence of circumstellar interaction?
P. A. Mazzali, S. Benetti, M. Stehle +5
The near-maximum spectra of the Type Ia SN 1999ee are reviewed. Two narrow absorption features corresponding to the strongest component of the CaII IR triplet appear in the spectra…
Dark energy effects on the Lyman-alpha forest
M. Viel, S. Matarrese, Tom Theuns +2
In quintessence models, the dark energy content of the universe is described by a slowly rolling scalar field whose pressure and energy density obey an equation of state of the for…
