Interpretation of the Cosmological Metric
Richard J. Cook, M. Shane Burns
The cosmological Robertson-Walker metric of general relativity is often said to have the consequences that (1) the recessional velocity of a galaxy at proper distance ob…
Quantitative comparison between Type Ia supernova spectra at low and high redshifts: A case study
G. Garavini, G. Folatelli, S. Nobili +44
We develop a method to measure the strength of the absorption features in Type Ia supernova (SN Ia) spectra and use it to make a quantitative comparison between the spectra of Type…
Spectra of High-Redshift Type Ia Supernovae and a Comparison with their Low-Redshift Counterparts
I. M. Hook, D. A. Howell, G. Aldering +32
We present spectra for 14 high-redshift (0.17 < z < 0.83) supernovae, which were discovered by the Supernova Cosmology Project as part of a campaign to measure cosmological paramet…
Spectroscopic confirmation of high-redshift supernovae with the ESO VLT
C. Lidman, D. A. Howell, G. Folatelli +44
We present VLT FORS1 and FORS2 spectra of 39 candidate high-redshift supernovae that were discovered as part of a cosmological study using Type Ia supernovae (SNe Ia) over a wide r…
The Hubble Diagram of Type Ia Supernovae as a Function of Host Galaxy Morphology
M. Sullivan, R. S. Ellis, G. Aldering +41
(Abridged) We present new results on the Hubble diagram of distant type Ia supernovae (SNe Ia) segregated according to the type of host galaxy. This makes it possible to check earl…
