Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples
M. Betoule, R. Kessler, J. Guy +60
We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The data set includes several l…
The Shape of Cas A
J. Craig Wheeler, Justyn R. Maund, Sean M. Couch
Based on optical, IR and X-ray studies of Cas A, we propose a geometry for the remnant based on a "jet-induced" scenario with significant systematic departures from axial symmetry.…
Joint Efficient Dark-energy Investigation (JEDI): a Candidate Implementation of the NASA-DOE Joint Dark Energy Mission (JDEM)
Arlin Crotts, Peter Garnavich, William Priedhorsky +15
JEDI will probe dark energy in three independent ways by measuring the expansion history of the universe: (1) using type Ia supernovae as cosmological standard candles over a range…
Broadband Observations of the Afterglow of GRB 000926: Observing the Effect of Inverse Compton Scattering and Evidence for a High-Density Environment
F. A. Harrison, S. A. Yost, R. Sari +21
GRB 000926 has one of the best-studied afterglows to-date, with multiple X-ray observations, as well as extensive multi-frequency optical and radio coverage. Broadband afterglow ob…
Evolution of Type Ia Supernovae on Cosmological Time Scales
Inma Dominguez, Peter Hoeflich, Oscar Straniero +1
Due to their high luminosity at maximum and degree of homogeneity, Type Ia supernovae have been extensively used for cosmological purpouses, in particular to estimate extragalactic…
