  1. COSMOS Magellan Spectroscopy Chris Impey and Jonathan Trump Steward Observatory Martin Elvis (CfA), John Huchra (CfA), Pat McCarthy (Carnegie)

  2. Magellan IMACS • Inamori Magellan Areal Camera and Spectrograph • Multi-object spectrograph • 30’ diameter field Our configuration: • 5400-9200 Å spectra • 1” × 11” nod & shuffle slits • Resolution: 10 Å

  3. Tiling Strategy Top: XMM coverage (RA is reverse from at right). Edge effects necessitate overlap Right: Single-pass IMACS strategy, ~5 hours each field

  4. 30’ Slit Maps Field 11, with 221 targets Mask / Sky Plane Detector Plane

  5. Targeting Strategy and Yields Six types of targets with i’<24: • x-ray selected AGN (XMM), priority 1 • radio selected AGN (VLA), priority 2 • BZK, priority 3 • Optically selected z~3-5 AGNs (Peter), priority MH • B, V, and i dropouts (Mauro), priority 3/3/MH • z>1.5 phot-z selected galaxies (Bahram), priority 5 • Yields (average of center fields): • 60% xagn (54/89) • 37% ragn (28/76) • 14% bzk (2/14) • 100% oagn (15/15) • 10% bdrop (55/574), 6% vdrop (7/126), and 100% idrop (2/2) • 4% highz (57/1468)
