J=20. 1 H=19. 8 T. Goto

Current status • Open for common use starting 10 A. • Only IRS 1, low resolution mode available (200 fibers). • Full 400 fibers, high-resolution will be operational from 11 A. T. Goto

Continuum sensitivity For 1 hour, 4 pix, S/N=5 at (ABmag) In reality, 1. 05 -1. 7 um T. Goto

Line sensitivity For 1 hour, S/N=5 at 1 x 10 -16 erg/cm 2/s Corrected for fiber loss T. Goto

Proposal deadline 9/30/10 FMOS instrument team is preparing a proposal. T. Goto

FMOS team SSP proposal draft • Galaxy/AGN , SXDS – Photoz sample 10 nights, – X-ray AGN: 10 nights – Emitter : 5 nights • • • Cluster: 16 nights Subaru deep field (photoz+emitter) : 8 nights AKARI NEP (mid-IR source) : 5 nights Redshift space distortion : 50 nights Pending : 10 nights. – Total 140 nights (including weather factor). T. Goto

Why not COSMOS field? • HST morphology is irreplaceable. • Accurate photo-z is essential when continuum sensitivity is not good. • Many one line only detections expected. Need photo-z to use data. • X-ray, Spitzer, Herschel coverages are better than other large field. T. Goto

Public COSMOS data • RA (J 2000) = 10: 00: 28. 6, DEC (J 2000) = +02: 12: 21. 0 • 588 orbits of HST/ACS, ~2 million objects to IAB < 27; • Photo-z accurate to Δz < 1% (30 bands) – GALEX, CFHTui, – Subaru (Bvgri, z =26. 5 AB+13 Int. bands, NBs) – UKIRT YHK, KPNO J, • X-ray – XMM – Chandra ~1700 Chandra sources down to 6 10 -16 cgs, >half with spectroscopic redshifts. 1. 8 Ms, 1 sq. deg, @160 ksec, 1761 sources (Elvis et al) • IR – Spitzer IRAC/MIPS, 3, 4, 5, 8, 24, 70, 160 um. 24 um>0. 42 m. Jy. • RADIO, VLA • Spectra – ZCOSMOS, 10, 000 spectra at z<1 T. Goto Maximum science output from rich data sets (HST, photoz…)

Cosmos data in future – Ultra. Vista Y=26. 7, J=26. 6, H=26. 1, K=25. 6 – Herschel PACS/SPIRE (100, 160, 250, 350, 500 um) – WFC 3 data 0. 1 sq. deg T. Goto

Excellent Spitzer coverage T. Goto

N sources • • • X-ray sources XMM: 1886, Chandra 1761 24 um: 17713 70 um: 1513 160 um: 499 VLA: 2901 Photoz: 1<z<1. 6, 39582 galaxies. – => FMOS T. Goto

FMOS 1 hr sensitivity T. Goto

My proposal to the FMOS team • 1<z<1. 6 with Hβ, [OIII], Hα • Hα flux>3 x 10 -16 erg/s/cm 2 (1 hr exposure) – 18277 galaxies – 18277/400 x 2 hrs, => 11 nights – could include • 24 um sources • X-ray sources • LAE/LBG at high-z T. Goto

My proposal to the FMOS team Science cases at 1<z<1. 6 • 100 Mpc scale, includes rich cluster to field(5 x 106 Mpc 3) – LF, MF, HαLF, SFRD – Morphology, environment, SFR – AGN/SB – X-ray/radio/IR sources – Obscured sources… • With spec-z and Hαluminosity T. Goto

Response were very interesting…. . T. Goto

FMOS teams response: “Tomo, What you are saying is absolutely right. ” “COSMOS is the best field to observe. ” But…. COSMOS cannot be included in the initial targets because… part of us are cosmos members. “This is a complicated political issue, Tomo” ? ? ? T. Goto

So COSMOS won’t be in initial targets. I failed. According to Japanese tradition, I should do HARAKIRI But not so soon, T. Goto

T. Goto

• FMOS team does not want to PI COSMOS field, but they welcome someone else to do the field. • SSP must open the proposal to entire Japanese community. They will accept proposal for additional field. • “Tomo, COSMOS stands a good chance. ” My life is saved! T. Goto

Summary • COSMOS is a good target for FMOS SSP. • It won’t be in the initial list of targets. • But it is likely, to be added to targets at later stage, if we keep pushing. • We can do a lot with 20 k NIR spectra. T. Goto
