Hubble Space Telescope and Ground-Based Observations of Type Ia Supernovae at Redshift 0.5: Cosmological Implications
A. Clocchiatti, B. Schmidt, A. Filippenko +26
We present observations of the Type Ia supernovae (SNe) 1999M, 1999N, 1999Q, 1999S, and 1999U, at redshift z~0.5. They were discovered in early 1999 with the 4.0~m Blanco telescope…
Physical Constraints From Broadband Afterglow Fits:GRB000926 as an Example
Sarah A. Yost, Re'em Sari, Fiona A. Harrison +6
We develop a model to fit the broadband afterglows of GRBs from the intrinsic parameters of the fireball's synchrotron emission, and apply it to a few well-studied events, with the…
The Afterglow and the Host Galaxy of the Dark Burst GRB 970828
S. G. Djorgovski, D. A. Frail, S. R. Kulkarni +3
GRB 970828 was the first well-localized gamma-ray burst (GRB) X-ray afterglow for which no optical afterglow was found despite a prompt, deep search down to R_lim ~ 24.5 mag. We re…
The Cosmic Gamma-Ray Bursts
S. G. Djorgovski, D. A. Frail, S. R. Kulkarni +12
Cosmic gamma-ray bursts are one of the great frontiers of astrophysics today. They are a playground of relativists and observers alike. They may teach us about the death of stars a…
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…
Beaming in Gamma-Ray Bursts: Evidence for a Standard Energy Reservoir
D. A. Frail, S. R. Kulkarni, R. Sari +11
Gamma-ray bursts (GRBs) are the most brilliant objects in the Universe but efforts to estimate the total energy released in the explosion -- a crucial physical quantity -- have bee…
