• • It's late where he is Normally a postdoc working in Lyon who's a fan of hosts, spectroscopy and classification :).

Notes:

Transients of the Week:

• https://fritz.science/source/ZTF21aaampui: remote event
• https://fritz.science/source/ZTF18aafzers: SN in AGN
• https://fritz.science/source/ZTF21aafkpnp: low luminosity host

Joel Spectroscopic Update:

• 1100 spectra of 800 SNe. 800 spectra are from SEDm+P60.
  • 240 SNe have a spec-z; 300 SEDm+P60 spectra of these.
• Most very early spectra are external. Most SNe have pre-peak spectra. Most redshifts are SN_z's.

• • ZTF18aarunub (from 2019) is a weirdo: very high velocity at max (16,000km/s)
  • Using spextractor to measure velocities and will soon expand to SN properties.

Closing Remarks:

• Mickael has pulled together the Y1 sample into an internal data release:
  • https://github.com/ZwickyTransientFacility/ztfcosmodr
  • Check it out.
• Back next week for more fun :).
