Description | We propose deep PACS 110/160 micron imaging for two of the most distant rich clusters ever discovered at z=1.6. These spectroscopically confirmed clusters are drawn from the homogeneously selected Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS), and have impressive spectroscopic coverage (a total of 26 confirmed members) and extensive multi-wavelength follow-up data (UV-MIR). This epoch marks a crucial turning point in the star formation rate-density relation: limited studies have shown that star formation shifts toward higher densities at zvirgul1, and even peaks in a z=1.6 cluster core, albeit only a single cluster at this distance has been observed in the IR until now. Moreover, MIPS imaging has already identified nine cluster members, confirming that dust enshrouded star formation is occurring in these dense fields. We will use the PACS/MIPS data, in combination with the extensive optical spectroscopy and photometry, to characterize the nature of IR-luminous galaxies in clusters at z=1.6. We will also measure the total star formation rate in these clusters, which will be used to study the effect of environment on galaxy formation at an exciting new redshift regime. |

Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
