Star formation rate density at z=0.24
The research project about the star formation rate density of the Universe at z=0.24 was born as a natural extention of the UCM survey
The purpose of the project is to study the evolution of the star formation rate density of the Universe with the same tracer, the emission line Hα, from z=0 to z=0.8. At z=0.40, the Hα line lies near 1000 nm. It is the higher redshift at it can be detected with a CCD.
The filters used are centered around 820 nm, where there exists a local minimum in the OH bands of the sky spectra. That wavelenght corresponds to a redshift of z=0.24 for the Hα line.
Two narrow-band filters were designed, with an aproximate width of 50 Å, for the WFC of the INT telescope. The filters are WFC8160 and WFC9190. The first one was used to probe the redshift z=0.24, whereas the second was used to explore the redshift z=0.40.
