—News and announcements—
Archisman:
- VSC next week, election of the Virgo-nEXT coordinator, election of the CBC working chair, final decision for Virgo-Brazil group
- Collaboration meeting tomorrow
- Update the data analysis activities (SVAC) on VMD!! The author list will be updated at the end of the month, if you don’t update your contributions you might be removed…
- Last BelGrav call before summer next week
— CBC updates —
UGent
Cezary: no major updates, monitoring events and preliminary analysis.
Archisman: no updates, same as Cezary; after Virgo entered the observing run there have been a few good well localized events.
— Bursts updates —
ULiege
Matteo: MMT group: Matthias has been elected as subgroup co-chair; analysis of second chunk of GRBs with X-pipeline has started, tomorrow (4.30pm) there will be a call to discuss the first closed boxes of this latest chunk of GRBs.
Maxime: Presented GWpyxel closed box results for O4a: clean background; comparison for 50%Hrss with other pipelines, GWpyxel better than PYstampas for most of the waveforms (worse performances for NCSACAM waveforms though), competitive pipeline on long bursts side; burst review chair of GWpyxel: review starts from beginning of August; concerned about timeline, hopefully to be done by November-December to not delay O4a all-sky long duration paper.
UCLouvain
Matthias: speeding up neutrino part, seeing how sensitive analysis will be soon; MMT group: starting GW neutrino follow-up with Matteo, Patrick, Iara and Wasim (student of Patrick), waiting for answers from Iara and Patrick to set up the analysis then start
— Instrumentation - optics updates —
UCLouvain
Ricardo: setting up phase camera at UCLouvain (before it was borrowed from Amsterdam group), now it’s integrated in system and fully working; we are at point where we where with the previous scanner; testing small optical cavity, making sure phase camera working
UGent
Daniela: ET Pathfinder: difficult having silicon mirror, considering idea flat end mirror, working on optical simulations to see if it is doable; Archisman: what is the gain in the Fabry-Perot cavity of ET Pathfinder (Daniel: i.e. finesse)? Hans: about a few hundreds
