Friday the 15th

The Friday will be structured discussions of about 30min to 1h each. Sessions will start by 2/5 min introductions.

8h45-9h00 Introduction

Marek's introduction

9h00-10h30 "SN cosmology"

Chairman: Jakob Nordin
show questions

How can we improve the use of SNe Ia as empirical Standard candles? When we claim to do "precision cosmology", how far can we go with empirical corrections? How can we convince ourselves and the community that there is no hidden potentially significant systematic bias for cosmology?

  • What can we use SNe Ia for? (20min)
    Intro Slides: Greg Aldering
  • How do we disentangle intrinsic from extrinsic reddening, and how to avoid systematic uncertainties? (20min)
    Intro Slides: Rahman Amanhulla [slides]
  • How well can we use environment (host) data to measure and correct for potential SN brightness redshift evolution? (20min)
    Intro Slides: Mickael Rigault [slides]
  • The SN opportunities in Future Surveys (20min)


11h00-12h30 "SN Typing and Modelling"

Chairman: Mark Sullivan
show questions

How many SNIa subtypes are there? Does this matter? What purity is needed for photometric typing? Can we get there? How important are the direct identification of progenitors as confirmation? What kind of very early data (type, quantity, quality) are needed to accurately test viable models?

  • How to separate SN types and SN Ia subtypes? (40min)
    Intro Slides: Bob Nichol [no slides]
  • Modelling Supernovae (50min)
    Longer Intro Slides: Fritz Roepke [slides]
    Follow-up Slides: Stefan Taubenberger [slides]


13h45-15h45 "SN project and funding"

Chairman: Marek Kowalski
Longer Intro Slides: ESO Perspective, Bruno Leibundgut (20min + Discussion) [slides]

The European Cosmological impact, our to do list (45min)
Follow-up Slides: 4MOST, Reolof de Jong (20min + Discussion) [slides]
(see google-doc in home page)


16h00-17h30 "SN Calibration and anchoring"

Chairman: Pierre Antilogus
show questions

TO BE RESHAPED -- Is physical calibration required, and are current suggested methods sufficient? How good can calibration be from ground? Should we create a set of joint photometry libraries? How do we determine which method/methods to use for standardization? Can we build a shared software effort?

  • Photometric Calibration (45min)
    Intro Slides: Nicolas Regnault
  • The anchoring Sample: How many, with which Data? (45min)
    Intro Slides: Manu Gangler

17h30-18h00 "SN and Computer"

Chairman: Mickael Rigault
Shared Software development Shared repository (30min)
Intro Slides: Kyle Barbary [slides]
