Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples
Aims. We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The dataset includes several low-redshift…
Explosion Diagnostics of Type Ia Supernovae from Early Infrared Spectra
Models of infrared spectra of Type Ia supernovae around maximum light are presented. The underlying dynamic models are delayed detonation explosions in Chandrasekhar mass carbon/oxygen white dwarfs.…
Broadband Observations of the Afterglow of GRB 000926: Observing the Effect of Inverse Compton Scattering and Evidence for a High-Density Environment
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 observations,…
Evolution of Type Ia Supernovae on Cosmological Time Scales
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 distances and the…
Joint Efficient Dark-energy Investigation (JEDI): a Candidate Implementation of the NASA-DOE Joint Dark Energy Mission (JDEM)
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 of distances, (2)…
Multiwavelength Observations of Tidally Induced Star Formation in the M81 Group
This project was funded by the Spitzer Space Telescope Observing Program for Students and Teachers, a joint project of NASA and NOAO. We also acknowledge the NOAO Teacher Leaders in Research Based…
Spitzer Studies of Supernova ejecta and dust
The optical counterpart of GRS 1009-45 (X-ray Nova Velorum 1993).
We report the discovery of the optical counterpart of the X-ray transient GRS 1009-45 (XN Vel 1993). From an analysis of photometric and spectroscopic observations at early and late stages, we are…
Spitzer Observations of a Nearby Supernova (SONS): SN 2004dj in NGC 2403
Type Ia supernovae: Pulsating delayed detonation models, IR light curves, and the formation of molecules
We computed optical and infrared light curves of the pulsating class of delayed detonation models for Type Ia supernovae (SNe Ia). It is demonstrated that observations of the IR light curves can be…
