Multi-wavelength galaxy surveys at the North Ecliptic Pole: from Herschel & AKARI to Euclid & SPICAStephen Serjeant JCMT UK meeting, September 2014

AKARI: Japanese/Korean mission 2006-2011

AKARI

Deep area covered bySCUBA2 (0.5 deg2)

Wide area covered byHerschel (9 deg2)

Murata et al. 2014 A&A

PAH deficit above the “main sequence”

V. Buat

8m rest-frame selected sample

Euclid (launch 2020)

Source: Euclid 2009 yellow book

Wide survey: 15,000 deg2 (above)Deep survey: ~2 mag deeper, ~40 deg2

NEP & East Asian surveys• Ideal location for probing solid-state phases

of ISM and e.g. connection to “main sequence” thanks to AKARI

• SCUBA-2 survey over 0.5 deg2 to 8mJy in CLS

• Future deep field for SPICA, Euclid etc
