7. zETA Telescope aperture: 4.0 meter diameter FoV 1 degree Image Quality 0.15 arcsec Camera: 0.16 arcsec/pix, 11X11 H2RG, or 30 H4RG, optimized for K-band Sensitivity: SN=5 (1hour) for a K=26.3 mag (AB) star, or 138 hours to reach K=29 mag A factor of 450 gain in efficiency as compared to VISTA (50 from background, 9 from seeing)

8. Observations The total amount of dark time at Dome A is 2606 hours/year (Zou et al. 2010, AJ, 140, 602). The strategy of the survey can be – 1380 hours/year on 10 deep fields to reach reach K = 29 (AB) – about 1000 hours evenly distributed to cover about 1000 sq degrees each year to a depth of 26.32 (AB) For comparison, the Ultra-VISTA survey is 5σ to a depth of 25.6 mag (AB) over a field of view of 0.73 deg 2.

9. zETA with KDUST The smaller aperture results in a lower efficiency, by a factor of 2.56 – 3-4 zETA deep fields to K = 29 – 1000 sq deg to about 25.3 mag For comparison, the Ultra-VISTA survey is 5σ to a depth of 25.6 mag (AB) over a field of view of 0.73 deg 2.

10. Pop III SNe

11. Pair Production SNe The predicted rate of first generation supernovae varies tremendously based on different models. – Mackey et al. (2003) have shown that the rate is ∼ 50 PISNe deg −2 yr −1 above z = 15 – Weinmann & Lilly (2005) have found a rate of ∼ 4 deg −2 yr −1 at z ∼ 20. – An even lower value of ∼ 0.34 deg -2 yr −1 at z ∼ 20 was given by Wise & Abel (2005) – using a Press-Schecter (P-S) formalism. Hummel et al. (2012) found an an upper limit of about 0.2 PISNe visible per JWST field of view at any given time and conclude that the main obstacle to observing PISNe is their scarcity rather than their faintness.

14. Flavors of Pair Production Supernovae Mass ~ 100-200 M  Mass ~ 15-40 M  In a hypothetical 1-year survey, the JWST should detect up to thousands of SNe (mostly core-collapse) per unit redshift at z ∼ 6. (Messenger, 2006)

15. Observations NIR light curves for five Pop III SNe at 2.0 μm at z = 15 (solid) and z = 20 (dotted). The horizontal lines are the detection limit for WFIRST (27 mag, AB) and JWST (32 mag, AB).The limiting magnitude of the zETA deep field is 29 mag (AB). (From Whalen et al. 2013, ApJ, 762, 6).
