A narrowband imaging survey of 276 square minutes of arc was carried out at near infrared wavelengths to search for emission line objects at high redshifts. Most of the fields contained a known...
Consequences of a Non-Detection of Forming Galaxies by an Infrared Survey (1996)
Mannucci, F., Thompson, D., Beckwith, S. V. W.
We present the results of a narrowband search for forming galaxies at high redshifts. Given the coverage of 276 square minutes of arc, this is the most extended search for extragalactic emission line...
