VLASS News:
- Data processing: Mark and Amy
- ¼ of sky done in Ep 2 SE continuum!
- New expedited 3-year data processing plan
- Possible change to 1” pixel scale in polarization cubes.
- To do: cross-check against polarization validation cubes made previously with 0.6” pixels
- Lerato will check with Pol group
- Question by Dillon: can you grid to 1” undersampled resolution and then just interpolate later? Could you make the gridding be dependent on local dynamic range?
- Mark: on-demand imaging interface coming that would address this . . .
- 50k hours (1% of total processing time) at Texas HPC center
- Different GPU architecture (“Grace-hopper chips”), not tested on VLASS pipeline
- Plans/testing underway for distribution of processing to external sites
- Documentation on the new plan is forthcoming
- Focus will be SECI mosaics
- Check impacts on astrometry of 1” pixels
- Science highlights:
- Dwarf Galaxies with Radio-excess Active Galactic Nuclei in the Very Large Array Sky Survey
- The Radiowave Hunt for Young Stellar Object Emission and Demographics (RADIOHEAD): A Radio Luminosity${-}$Spectral Type Dependence in Taurus${-}$Auriga YSOs
- COSMIC's Large-scale Search for Technosignatures during the VLA Sky Survey: Survey Description and First Results
- Calibration trends with time through separate correlation and calibration of the COSMIC data - Chenoa has a student working on this
- Finding Lensed Radio Sources with the Very Large Array Sky Survey
Events/Outreach:
- AAS:
- VLASS featured on NRAO booth displays
- Handouts available
- No due dates for AAS in Alaska yet
- Do we want Slack back (can use NRAO Slack channel)?
- Depends on how we want to communicate with the community going forward
What is the role of the SSG going forward? - Mark Lacy
- Using VLASS data and gathering user feedback is still valuable; publicizing the survey
- Development of future proposals for VLA surveys
- Scientific and technical validation (e.g. of 1” vs. 0.6” grid size)
- Send Juergen pol. Fields of interest
- Open questions on tapering to avoid undersampling higher-freq end of the cubes
- Input from polarization community requested
- Meeting content going forward
- How can the SSG help
- Science talks
- Should we have science presentations in a webinar series?
- Chenoa: could we encourage VLASS talks at TUNA, etc.?
- Advertising is problematic . . . could we do something similar to the Green Bank webinar series?
- People are interested!
- Median stack HIPS epochs 1-3 (Steve)
Future meetings: (subject to change; check your email for updates)
- TBD
