Star-Forming Galaxies at z=0.24 in the Subaru Deep Field and the Sloan Digital Sky Survey

Understand

We make a search for Halpha emitting galaxies at z=0.24 in the Subaru Deep Field (SDF) using the archival data set obtained with the Subaru Telescope.

• We carefully select Halpha emitters in the narrowband filter NB816, using B, V, Rc, i', and z' broad-band colors.
• We obtain a sample of 258 emitting galaxies with observed equivalent widths of (Halpha+[NII]6548,6584) greater than 12 angstrom.
• We also analyze a sample of Halpha emitters taken from the Sloan Digital Sky Survey (SDSS) to constrain the luminous end of Halpha luminosity function.
