Halpern,Tsvi Piran,Robert W. Goodrich,Frederic H. Chaffee,M. Feroci,Enrico Costa +28 more
TL;DR: In this article, optical and near-infrared observations of the afterglow of GRB990123 were presented, and a redshift of z ⩾ 1.6 was determined.

S. R. Kulkarni,S. G. Djorgovski,S. C. Odewahn,Joshua S. Bloom,Roy R. Gal,Christopher D. Koresko,Fiona A. Harrison,Lori M. Lubin,Lee Armus,Ramazan Sari,G. D. Illingworth,D. D. Kelson,Dan Magee,P.

Goodrich,Frederic H. Chaffee,M. Feroci,Enrico Costa +28 more
TL;DR: In this paper, the optical and IR afterglow measurements reported here may provide the first observational evidence of beaming in a GRB, thereby reducing the required energy consumption to a level where stellar death models are still tenable.
Journal ArticleDOI
Measuring the Magnetic Field on the Classical T Tauri Star BP Tauri
TL;DR: In this article, the authors examined several theories that describe how stellar magnetic fields on T T Tauri stars interact with their surrounding accretion disks, and demonstrated that these theories require magnetic field strengths ranging from a few hundred to several thousand gauss, depending on which model is used and more importantly on the properties of individual systems.
Journal ArticleDOI
Diffraction Limited Infrared Images of the Binary Star T Tauri

TL;DR: In this article, the spectral energy distribution of T Tau and its infrared companion was reconstructed from near and mid-infrared data collected at the Hale 5 m telescope using two dimensional speckle imaging.
Journal ArticleDOI
The Host Galaxy of GRB 990123

TL;DR: In this paper, the authors presented deep images of the field of gamma-ray burst (GRB) 990123 obtained in a broad-band UV/visible bandpass with the Hubble Space Telescope, and deep near-infrared images obtained with the Keck-I 10m telescope.
