VLASS News:
- Observing and data processing status: Amy Kimball and Mark Lacy
- Observing completed, QL imaging 84% done.
- VLASS epoch 3.2 observing finished
- Processing completion timeline: 3 years (more info at future meetings)
- Science highlights:
- Undergrad Rachael Howard RNAAS on spectral index asymmetries
- Accretion flares from stellar collisions in AGN (ML)
Events/Outreach:
- List of outreach idea here
- Conference updates?
- Winter AAS (National Harbor)
- Mark - general VLASS abstract
- Charlotte’s student will present a poster
- Dillon’s student will present on Stokes V imaging
- Kristina + students will present posters on AGN science involving VLASS
- Abstract deadline was Sept 26
- Propose a Jan 26 AAS Special session on high resolution radio surveys?
- Deadline for special sessions is ~spring or summer before
- Call for white papers?
- Scope tbd (highlight VLASS, new ideas)
- YES
- What is the next VLA survey going to look like?
- Start planning in early 2025 (after AAS)
- Review outcome
- Re-prioritization for high-level data products processing: Steve
- 5-10k sq degrees, at least one epoch of full products . . .
- Validation fields?
- Need to be above -4 deg dec to avoid need for awproject
- Plan will be finalized by end of 2024
- What areas should we focus on (starting with 2.1)?
- Plan is still being developed . . .
- Limitations on declination/algorithm requirements - south of Dec 4 deg will need to use w-project, so much slower
- Stripe 82 (VLASS + POSSUM collaboration?)
- LOTSS
- Galactic center
- POSSUM
- Focus on polarization
- CDFS
- Lerato and Jennifer will share fields for validation with NRAO
- New Polarimetry data products now available (Lerato)
- Details on Slack
- Link: tbd
- Dillon’s new tools
- New VLASS cutout server API that prioritize speed/efficiency
- Prototype available: https://vlasscutouts.ngrok.io/cutout?ra=358.9545833&dec=30.7633750&epoch=2&size=61&outputpix=250&plow=1&pmax=100
