SAG1/SDP-050: High RedshiftPart 1: Brainstorming Session

organizer: Darren Dowell2009 May 27

Team & Deadlines

• Local commitments: Jason G., Joaquin V., Mike Z.

• Need commitments from a few key on other side of Atlantic.

• SDP abstract due June 1• Presentation (remote?) at SAG1 meeting in Paris

June 15

Paper Title

• “Candidate Far-Infrared-Selected Galaxies at z > 5 from Herschel Surveys”

ProspectsSpitzer + PACS + SPIRE + (sub)mm

Spitzer + PACS + SPIRE

PACS + SPIRE

quasars at z > 5 easy to ID?(but low numbers?)

fairly easy to ID, but only a lower limit to z?

fairly east to ID, but only a lower limit to z?

SMGs at z > 5 possible to ID statistically?

very difficult? very difficult?

other

Dusty quasars at z > 5

Wang et al. (2008)

Beelen et al. (2006)

PACS, z=5

SPIRE, z=5

F ~ -1

Quasar Surveys: Problems

• How many (few) are there of these in 10’s of square degrees?

• Will the quasars be catalogued already by other means?

SMGs

Kovacs et al. (2006)Pope et al. (2008)

PACS, z=5

SPIRE, z=5

SPIRE, z=5

SMGs

• Generally steeper slope on the Wien side compared to the quasars

• Spectral diversity – take statistical approach?

Miscellaneous

• We (SAG1) are encouraged to be the first ones following up these sources– Start with SMA, CARMA, IRAM PdBI to get

accurate dust positions
