Abstract:
We present Hα-derived SFRs for three z∼0.75 galaxy clusters. Our
1σ flux limit corresponds to a star formation rate (SFR) of
0.10-0.24h-2100M_☉/yr, and our minimum reliable Hα+[NII]
rest-frame equivalent width is 10Å. We show that H narrowband
imaging is an efficient method for measuring star formation in distant
clusters.
