We report the discovery of a highly luminous optical transient (OT), SDSS J124602.54+011318.8, associated with a galaxy at a redshift of 0.385. In this paper we consider the possib…
Frequentist Estimation of Cosmological Parameters from the MAXIMA-1 Cosmic Microwave Background Anisotropy Data
M. E. Abroe, A. Balbi, J. Borrill +12
We use a frequentist statistical approach to set confidence intervals on the values of cosmological parameters using the MAXIMA-1 and COBE measurements of the angular power spectru…
Observations of T-Tauri Stars using HST-GHRS: I. Far Ultraviolet Emission Lines
D. R. Ardila, G. Basri, F. M. Walter +2
We have analyzed GHRS data of eight CTTS and one WTTS. The GHRS data consists of spectral ranges 40 A wide centered on 1345, 1400, 1497, 1550, and 1900 A. These UV spectra show str…
The Unusually Long Duration Gamma-ray Burst GRB 000911
P. A. Price, E. Berger, S. R. Kulkarni +18
Of all the well localized gamma-ray bursts, GRB 000911 has the longest duration (T_90 ~ 500 s), and ranks in the top 1% of BATSE bursts for fluence. Here, we report the discovery o…
Flux-loss of buoyant ropes interacting with convective flows
S. B. F. Dorch, B. V. Gudiksen, W. P. Abbett +1
We present 3-d numerical magneto-hydrodynamic simulations of a buoyant, twisted magnetic flux rope embedded in a stratified, solar-like model convection zone. The flux rope is give…
