Participants (15):

• Mickael R, Mat S, Joel J, Alice T, Bastien C, Benjamin R, Estelle R, Jeremy L, Kelian S, Leander L, Manu G, Maxime D, Melissa A, Nicolas R, Philippe R
• Apologies: Kate M, Remy J

Transients of the Week:

• Only 16 new Ia's this week. The moon is up and telescope is also down for 3 days.
• ZTF21acpmcgo: highly MW redenned Ia. There are ~80 of these. Join this project!
• ZTF19acykjad: sibling, AGN or rebrightening?
  • This means we now have 17 confirmed Ia-pair siblings; 30 confirmed+photometric. Another 30 ZTF + archival events.
  • This is clearly a paper / analysis. They are highlighted in the fritz 'samehost' group.
• We also have 3 low luminosity host events and one remote event.
• ZTF21acpfndw - caught young.
• ZTF21aarqkes: calibrator event
• ZTF21aclhsxb: caught early: being followed by Adam

New Members:

• Leander Lacroix: a PhD student working in Paris with Nicolas R + Ariel G.
  • Going to be implementing a Scene Modelling Photometry Pipeline for ZTF.
  • The plan is to adapt the SNLS pipeline. Hoping to have a first pass pipeline by the new year, with all of DR2 by March.
• Kélian Sommer: a PhD student in Montpellier.
  • Planning to working on an analysis of the strength of the secondary-max of SNeIa and whether it can be used to improve standardisation for the DR2 sample
• Alice Townsend: a PhD student working with Jakob Nordin in Berlin
  • Hopefully going to be working with AMPEL

HyperGal Update:

• Jeremy has started the first production run of the new and improved SEDm pipeline.
  • 280 events have been run: only a small subset failed. Currently debugging to pull out the remaining events.
  • There are some really, and I mean really, promising results (e.g. ZTF20aalfyj, ZTF18acutfne)
  • The first spectra should be circulated next week. Let's look at them!
  • Also thinking about redshift determination: thats the next step

Simulations:

• The plan is to have a meeting next Thursday to discuss who's doing what with simulations.
• Let's check that we're all on the same page and using the same base files. Slack Mat if you want to join

Closing remarks:

• Fill in the spreadsheet to volunteer.... Suhail next week
