Motivation

Few spectroscopically confirmed clusters at z>1.5.

Gaël Noirot CARLA HST Results Paris Cluster Workshop 2016/10/06

Mei+15 + few others, e.g.,

  • Webb+2015 @z=1.709
  • Wang+2016 @z=2.506

=> Need of dedicated surveys spectroscopically confirming high-z clusters.

CARLA - ‘‘Parent’’ survey

๏ 400hr Warm Spitzer/IRAC [3.6] and [4.5] µm program. ๏ 5.2 x 5.2 arcmin2 per field. ๏ 420 fields targeted around RLAGNs. ๏ 209 HzRGs (type-2), 211 RLQs (type-1). ๏ 1.3 < z < 3.2, L500MHz ≥10^27.5 W/Hz. ๏ Source selection: ([3.6] - [4.5])AB > –0.1 (=> z > 1.3). ๏ CARLA Clusters: fields with >2σ overdensity of red sources.

Primary goals:

๏ Spectroscopically confirm most promising CARLA cluster candidates. ๏ Increase nb of high-z spec-confirmed clusters by factor of several. ๏ Provide benchmark sample for future detailed studies.

(P .I. Stern)

Observations (completed):

๏ 2-orbit per field. ๏ 2x2.3 arcmin2. ๏ 1ksec F140W imaging. ๏ 2x2ksec G141 slitless grism spec.

  • 10800-17000 Å (Ha, OIII, or OII).
  • ~3e-17 erg/cm2/s line detection limit (SFR~20 M⊙/yr at z=2).

Summary & Prospects

Gaël Noirot CARLA HST Results Paris Cluster Workshop 2016/10/06

Summary:

๏ Efficient confirmation strategy (small 40-orbit HST program, 22 spec-confirmed clusters). ๏16 spec-confirmed clusters associated with RLAGN at 1.4<z<2.8. ๏ Additional data available support the confirmations.

A few prospects:

๏ Obtaining optical data to study CMRs for all confirmed clusters. ๏ Obtaining mm data to study molecular gas on a few confirmed clusters. ๏

Your thoughts on where to go next?
