A part of the workshop will be dedicated to breakout sessions, allowing smaller groups of people to come together and discuss specific topics. At the end of the workshop, there will be a final session, where outcomes of the breakouts can be presented to the plenum.
Below is a list of potential breakout topics. We warmly welcome additional ideas from the participants and encourage you to share your suggestions with us. At the beginning of the workshop, we will split into the different groups based on interest, keeping only those that have at least ~ four participants.
Simulation requirements for next-generation mock challenge
Convener: Elisabeth Krause
Scope: Provide feedback on ELG mock challenge design document from the future analysts' perspective: e.g., which analyses could use rescaled simulations based on control variate techniques? given finite computing time, how would different teams prioritize number of realizations vs. simulation volume? what is the role that approximate simulations can play? which validation plots/comparisons with data would different analyes want to see to consider an ELG assignment "sufficiently realistic" to be worth their time?
Target group: experts on different summary statistics (in particular void, WST, field level), control variates, ELG modeling
Bounding theory systematics (as function of scale)
Convener: Fabian Schmidt
Scope: Can we come up with principled bounds of modeling error up to a given scale for different approaches? E.g., EFT, HEFT, HOD, SHAM(e), ... This group would discuss any answer that is not "validate on this or that set of mock catalogs" (we agree that that validation needs to be done anyway).
Target group: people working on models for summaries or forward models in general
Tutorial on analyzing beyond-2pt mocks
Convener: Yosuke Kobayashi (?)
Scope: Help-desk (and quiet work time) for anyone interested in getting started analyzing the beyond-2pt challenge mocks.
Target group: people with codes ready to analyze galaxy mocks
Best practices for publishing beyond-2pt analysis results
Convener: Julia Stadler
Scope: Review validation+convergence tests favored by different teams, develop short document on best practices for publications describing the complementary of different tests.
Target group:
Systematics in beyond 2-point statistics
Convener: Jinging Shi
Scope: We will discuss the various systematics in galaxy clustering, include survey systematic, e.g. fiber assignment, imaging systematics, etc. and analysis systematics, e.g, HOD prior, covariance matrix. Specifically, we will discuss the proper way to construct the mocks that can be used to test these systematics for various surveys, including DESI, PFS, Euclid.
Target group: experts from different analysis teams, people having experience with systematics in galaxy surveys
