We report preliminary results of a deep near-infrared search for methane-absorbing brown dwarfs; almost five years after the discovery of Gl 229b, there are only a few confirmed examples of this type...
The Surface Density of Extremely Red Objects (1999)
Thompson, D., Beckwith, S. V. W., Fockenbrock, R., Fried, J., Hippelein, H., ...
We present initial results from a field survey for extremely red objects (EROs, defined here as (R-K') >= 6 mag) covering 154 square arcminutes of sky, from the first of 7 deep, wide-field K' images...
Evidence for Diverse Optical Emission from Gamma-Ray Burst Sources (1997)
Pedersen, H., Jaunsen, A. O., Grav, T., Ostensen, R., Andersen, M. I., Wold, M., ...
Optical Transients from gamma-ray burst sources, in addition to offering a distance determination, convey important information on the physics of the emission mechanism, and perhaps also about the...
