--------------------------------------------------------------------------------------------- [General Discussion] 1) Science Topics, sub-WGs, AIs and 1st year scientific projects 1.very high-z QSOs (z >6) : PI Kashikawa [science] -Survey strategy and "actual" discovery@z=7 -Discovery@z=6 #on the issue of faint end of AGN LF -Galactic BD based on photometric sample [A/I] -probabllistic selection -NIR(UKIDSS/VIKING):examinig actual data -Identifying problems in images: software team -Repeat/confirming photometry -spectra:individual proposals? ex -optical follow-up imaging ? #If we obtain, we will propose to write optical(z-band) follow-up. #20 min, 8m telescope for each targets # how about 4m telescope ? probably ok #Learn from SDSS -preparation for ALMA &JVLA proposals: QSO@z=8 -Galactic BD sciences ? spatial distribution Y dwarfs ? How we should do for faint candidatesin UD without spec 2. z=3-5 photometric selection (lower redshift too):PI Nagao [A/I] -multi-color selection (not 2color-based) -stellarity criteria -Effects of Baldwin effect  -proper motion(SDSS-HSC; a few yr time separtion only bright QSO(z=7) is useful (morokuma-san) =>we should check this at lower-z 3. Clustering and environment: PI Strauss [sicence] -cross correlation -z=4 g-drop LBGs with HSC (dep. on L) -low z galaxies with photo-z (dep. gala properties) (cluster of galaxies) [A/I] -Revising Mock catalog -communication with galaxy people  4. Lensed QSOs: PI Coupon [science] -mutiple-image lensed QSOs -> host galaxies studies #quite rare, less than few #SDSS QSOs [A/I] -spectra: individual -other follow-up needed NIR? imaging? 5. QSO metallicity: PI Nagao [science] -z_BLR evolution, by product of the collected spectra [A/I] -NIR follow-up -model predictions from theoretical works =>Already build-in! (but TOTAL metallicity Z) =>relative abundance can be also added (but though issue) 6. variability: PI Morokuma [science] -long-term year with HSC & previous data => structute func if focus on Subaru data (SDSS) time sampling is so dense saturation is worried on SDSS obs.  [A/I] -completeness -incoprating variability in target selection, algorism 7. Mid : PI Silverman [A/I] -completness/contamination -spectra -SPLASH dataset(spa.resolution 3-4")  what we should do ?  Host galaxies of low-L AGN at z-1(rest K)=> Mstar  extremely high-z (>20??) 8. X-ray: PI Terashima [science] -pecullar SED objects -2color -including obscured pop => f_abs z=4-5 -optical couterparts of opt-undetected cahndra obs @cosmos  data coming soon within 1yr [A/I] -spectral -X-ray follow-up of interesting AGN  9. Radio/sub-mm: PI Nagao [A/I] -new members -inviting radio people? -JVLA new survey -CCAT(timescale is too long) -Japanese radio community meeting@mitaka (->Imanishi-san) 10. Models: Wada -AGN downsizing -nexr SWANs theory meeting @ sendai  LOC chair: Akiyama-san 2) HSC data [Need some coordination?] through telecon to maximize the multipllicity of spectrographs to avoid submissions of multiple similar proposal [which telescope?] -subaru, gemini,keck -subaru-VLT time-exchange  -smaller telescope, APO, WHT, AAO?  access from APO: end at summer 2014  CFHT/MegaCaM/WIRCAM(Taiwan, but limited night) -before HSC data we submit the proposal. May not convincing ? -approach from both JP and Princeton dividing our target lists into two -proposal for multi-wavelength dataset  u-band in UD (next semestar SXDS done)  6-7 night for each semestar(Taiwan)  VISTA for HSC deep layer(40h) France and Brazil  ALMA JVLA -Instrumnetion issues -Other surveys to watch  VISTA  JVLA: propo0.2mJyfor wide layer       (TAC suspect survey)  Euclid:    eROSITA:  looking forward to TMT, JWST #Survey parameters (HSC) on web page??  should be confirmed 3) Follow-up 4) software and database issues 5) PFS: Science opportunities and target selection *target selection -How will AGN be selected in wide survey  deep survey -How will AGN be recognised from specra of galaxy sample ?  See Tanaka's simulations are useful -working to prepare the SSP *QSO photo-z Tanaka, Coupon with photometric guys [A/I] adding MIR component effects of variabillity baldwin effect cf. BOSS QSO catalog (Paris et al. 2012) type-2 QSOs  *HSC data and proposal a)HSC commissioning b)SSp 1st year obs VIKING(GAMA), XXL(K22) c)requirements for data under software continuous interaction with software WG -strengths and limitatios of HSC pipelines -early data reveal problems and features -features we identified we would like contact with Furusawa-san 6) Fostering further collaborations [Our activity] - presentation file => HSC members in other sub-WGs - each sub-group => continuing meeting (like Theory) - encouraging younger PDs/students -Next meeting? --joint meeting with galaxy evolution WGs --at where (NAOJ or IPMU would be convenient...)   April/May?    coordination with Cosomos meeting in kyoto   strauss-san will talk to takada-san -other good ideas/suggestions  Nothing
