“…In Figs 2-4 we show observational estimates for the CGLF from Strazzullo et al (2006Strazzullo et al ( , 2010 and Fassbender et al (2014), as well as our estimates based upon the data sets of Mei et al (2006b), Hilton et al (2009) andSnyder et al (2012). Strazzullo et al (2006Strazzullo et al ( , 2010 estimate the CGLF for their galaxy cluster sample by using a reference field, down to an equivalent photometric depth or deeper, to statistically remove the contribution from background galaxies, which is known to bias CGLF estimates (Andreon, Punzi & Grado 2005), particularly at bright magnitudes where the statistics are typically quite poor.…”

“…We select the GALFORM cluster galaxies using an aperture size of r < 120 arcsec, which is consistent with the apertures placed by Mei et al (2006b) and Snyder et al (2012). Given the cosmology used in the MS-W7 simulation, an aperture of 120 arcsec corresponds approximately to a distance of 500 h −1 kpc at z ∼ 1.4.…”

“…They attribute this to an enhanced sSFR in the cluster. In addition, based upon measurements of the Hα emission from galaxies in the Snyder et al (2012) clusters, Zeimann et al (2013) infer unobscured SFRs of up to 200 M yr −1 for galaxies right down in the cluster cores. SFR measurements of the same clusters from Spitzer 24 µm observations, as well as Herschel SPIRE data, find similarly high SFRs, with the SFR in clusters increasing rapidly with redshift (Brodwin et al 2013;Alberts et al 2014).…”

High redshift galaxy clusters allow us to examine galaxy formation in extreme environments.Here we compile data for 15 z > 1 galaxy clusters to test the predictions from a state-of-theart semi-analytical model of galaxy formation. The model gives a good match to the slope and zero-point of the cluster red sequence. The model is able to match the cluster galaxy luminosity function at faint and bright magnitudes, but under-estimates the number of galaxies around the break in the cluster luminosity function. We find that simply assuming a weaker dust attenuation improves the model predictions for the cluster galaxy luminosity function, but worsens the predictions for the red sequence at bright magnitudes. Examination of the properties of the bright cluster galaxies suggests that the default dust attenuation is large due to these galaxies having large reservoirs of cold gas as well as small radii. We find that matching the luminosity function and colours of high redshift cluster galaxies, whilst remaining consistent with local observations, poses a challenge for galaxy formation models.

“…The few studies at higher redshifts suggest that clusters at > z 1.5 are still in the process of forming (Snyder et al 2012;Mei et al 2015), and that although clusters at these redshifts show a mixed population of both star-forming (SF) and quiescent galaxies, even the reddest (early-type) galaxies show on-going star formation (Mei et al 2015). Star formation activity has also been observed in the cores of massive galaxy clusters at > z 1.4 (e.g., Hayashi et al 2010;Tran et al 2010;Zeimann et al 2013;Alberts et al 2014;Bayliss et al 2014).…”

Using Hubble Space Telescope slitless grism data, we report the spectroscopic confirmation of two distant structures atz 2 associated with powerful high-redshift radio-loud active galactic nuclei(AGNs). These rich structures, likely (forming) clusters, are among the most distant structures currently known, and were identified on the basis of Spitzer/IRAC [3.6]-[4.5] color. We spectroscopically confirm nine members in the field of MRC2036 −254, comprising eight star-forming galaxies and the targeted radio galaxy. The median redshift is z=2.000. We spectroscopically confirm 10 members in the field of B30756+406, comprising 8 star-forming galaxies and 2 AGNs, including the targeted radio-loud quasar. The median redshift is z=1.986. All confirmed members are within 500 kpc (1 arcmin) of the targeted AGNs. We derive median (mean) star-formation rates of based on mid-infrared fluxes and spectral energy distribution modeling. Most of our confirmed members are located above the star-forming mainsequence toward starburst galaxies, consistent with clusters at these early epochs being the sites of significant levels of star formation. The structure around MRC2036−254 shows an overdensity of IRAC-selected candidate galaxy cluster members consistent with being quiescent galaxies, while the structure around B30756+406 shows field values, albeit with many lower limits to colors that could allow an overdensity of faint red quiescent galaxies. The structure around MRC2036−254 shows a red sequence of passive galaxy candidates.

Observational evidence that massive cluster galaxies were forming stars atz~ 2.5 and did not grow in mass at later times

Using Spitzer 3.6 micron data we derived the luminosity function and the mass function of galaxies in five z > 1.4 clusters selected to have a firm intracluster medium detection. The five clusters differ in richness (ISCS J1438.1+3414 and XMMXCS J2215.9-1738 are twice as rich as ISCS J1432.4+3250, IDCS J1426.5+3508, and JKCS 041) and morphological appareance. At the median redshift z = 1.5, from the 150 member galaxies of the five clusters, we derived a characteristic magnitude of 16.92 ± 0.13 in the [3.6] band and a characteristic mass of lg M * = 11.30 ± 0.05 M . We find that the characteristic luminosity and mass does not evolve between z = 1 and 1.4 < z < 1.8, directly ruling out ongoing mass assembly between these epochs because massive galaxies are already present up to z = 1.8. Lower-redshift build-up epochs have already been ruled out by previous works, leaving only z > 1.8 as a possible epoch for the mass build up. However, the observed values of m * at very high redshift are too bright for galaxies without any star formation immediately preceding the observed redshift and therefore imply a star formation episode not earlier than z f = 2.5. For the first time, mass/luminosity functions are able to robustly distinguish tiny differences between formation redshifts and to set upper limits to the epoch of the last star-formation episode.
