Galaxy Evolution in a Pilot Survey up to 𝑧=1 and CDM Halos

Figure 2

(a) Magnitude redshift relation for the full sample. The three lines overploted over the measured points correspond to absolute R magnitudes of−22.5, −20.5, and −18.5. The distances have been calculated using a cosmology with Ω_0,Λ=0.70, Ω_0,𝑚=0.30, 𝑤=−1, and 𝐻₀=75kms⁻¹Mpc⁻¹ (ℎ=𝐻₀/75kms⁻¹Mpc⁻¹). Red dots are galaxies with no emission-lines and blue dots are galaxies with emission-lines. (b) Cone diagrams in Dec for all the galaxies measured in the field of RX J0054.0-2823. The scales is in Mpc calculated using the angular distance for the standard cosmology. The detection threshold for emission-lines is EQW([OII])∼2-3 Å. (c) Same as (b) but for RA.
