Day 8 of blog: wrote up why I didn't blog day 6 or 7 at Moscow airport. Boarding to Seoul should begin soon, and I won't have time to blog for the rest of the day...

The discovery and classification of 16 supernovae at high redshifts in ELAIS-S1: the Stockholm VIMOS Supernova Survey II [SVISS II]
Melinder, Dahlen, Mencia Trinchant, Östlin, Mattila, Sollerman, Fransson, Hayes, Nasoudi-Shoar
SNe are used to study: (i) cosmology via SNIa, (ii) SFR from core-collapse SNe, (iii) SNe connection to their host galaxies. SVISS is a multi-band imaging survey aimed to detect SNe at z~0.5 and derive two kinds (thermonuclear and core-collapse) SNe rates at high z. This paper presents photometric classification of the two types. Difference imaging is used to detect SNe; combine automatic and manual source detection to minimize spurious detections.
Photometry found for variable sources, simulation used to estimate errors. Lightcurves typed, and MC used to estimate misclassification rate. Misclassification ~5%, but vary with redshift and type. Mean z of SNe is 0.58. Also found an instability SNe.
