A Narrowband Imaging Survey for High Redshift Galaxies in the near Infrared
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 quasar or radio galaxy at a redshift that placed one of the strong, restframe optical emission lines (Hα, [O III], Hβ, or [O II]) in the bandpass of the narrowband filter. The area weighted line flux lim...
متن کاملNear-Infrared Emission Line Searches for High-Redshift Galaxies
In this article I review recent developments in near-infrared emission line searches for star-forming galaxies at high redshift. Using the J-, H& K-bands we can potentially chart the history of star formation over the range 1 < z < 5 using the prominent rest-optical nebular emission lines alone, filling in the “redshift desert” at z ∼ 1 − 3 where most common emission lines lie outside the optic...
متن کاملOn near - infrared H α searches for high - redshift galaxies ⋆
The lack of success of Lyα searches for high-redshift z > 2 field galaxies may be due to extinction by dust, suggesting that surveys based on lines of longer wavelength, particularly Hα, may be more effective. To test the dust hypothesis we have undertaken deep broad(K ) and narrow-band (5000 km s, λ = 2.177 μm) imaging of the field towards the quasar PHL957, in an attempt to detect Hα emission...
متن کاملCo and Near-infrared Observations of High-redshift Submillimeter Galaxies
I discuss our ongoing Owens Valley Millimeter Array observations and Keck nearinfrared wavelength observations of the high-redshift sub-mm population of galaxies. These observations are important for our understanding of the distant universe since the sub-mm population accounts for a large fraction of the extragalactic background at mm/sub-mm wavelengths and contributes significantly to the tot...
متن کاملDeep Near–Infrared Imaging Surveys and the Stellar Content of High Redshift Galaxies
Deep, near–infrared imaging surveys have been motivated by the desire to study the rest–frame optical properties and stellar content of galaxies at high redshift. Here we briefly review their history, and illustrate one application, using HST NICMOS imaging of the Hubble Deep Field North to examine the rest–frame optical luminosities and colors of galaxies at 2 < z < 3, and to constrain their s...
