• ZTF21abcmxgn: very young and in a cluster environment. Could be high velocity?
  • Too date for the fast U-band trigger project.
• ZTF21abxfyaw: beautiful; now at peak: 1.3 magnitudes of extinction (from MW). Can be used to estimate MW dust law.
  • This is going to be a paper at some stage; wave if you want to be involved!
  • LCO/LT for u->z band? Is SEDm oversubscribed for this? Contact Dan P for LT time.
    • There's LT data (U-band and NIR) for some objects from 2020; check to see the quality? this data has not been looked at properly.
• ZTF21abwtybk: stunning light-curve; now at peak.

• 4pm Wednesday (Europe time) is the preferred time from the doodle poll. Looking forward to Adam joining us!
  • This is 1 hour later of the existing time.
  • Last chance to vote is now!

The Sample:

• ZTFDR2 is coming together: Mat has pulled together all of the objects that we should be using for Ia population studies. We have 2000 cosmological Ia's
  • Of course this list is not complete, and needs to be refined
    • There are also lists from AMPEL (TNS classifications) and the Marshall that need to be pulled together
      • In short, no-one has a single list of everything that has been confirmed as a Ia from ZTF
    • Conclusion: this list needs to be online and available for everyone to access
      • Mat to work with Valery and Joel on this.
      • There are outliers that need to be dealt with: so there will also be comment files, which can be used to reject events
      • This is also a starting point for pulling together redshifts, etc. Note that BTS are reanalysing this, so that needs to be included.
      • Hopefully a starting list by next week
• Contact Mickael if you'd like to use the sample for a project

• Back next week: Bastien and Valery will provide updates.
