M. A. Malkan,V. Gorjian,R. Tam +2 more
TL;DR: In this article, the authors obtained 500-second F606W WFPC2 images of 256 of the nearest (z < 0.035) Seyfert 1,Seyfert 2, and starburst galaxies.
Journal ArticleDOI

TL;DR: In this article, the authors carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared wavelengths ranging from 3 to 22 μm, allowing them to refine estimates of their numbers, sizes, and albedos.
Journal ArticleDOI

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

TL;DR: A redshift survey at a wavelength of three millimetres, targeting carbon monoxide line emission from the star-forming molecular gas in the direction of extraordinarily bright millimetre-wave-selected sources, indicating that the fraction of dusty starburst galaxies at high redshifts is greater than previously thought.
