Multipole moment data for PT challenges


I provide multipole moments of the redshift-space power spectrum measured from mock galaxies created on this webpage.

Challenge participants and results

Participants Model Reference Submitted on Blind analysis
Mikhail Ivanov, Marko Simonović, Matias Zaldarriaga EFT 1-loop (see the challenge paper for detail) 0.12 arXiv:2003.08277 (East Coast Team) May 24th 2019 Yes
Guido D'Amico, Leonardo Senatore and Pierre Zhang EFT 1-loop (see the challenge paper for detail) 0.12 arXiv:2003.08277 (West Coast Team) Jun 4th 2019 Yes
Shi-Fan Chen, Zvonimir Vlah, Martin White MONE: Moment expansion using the first two pairwise-velocity moments at one-loop order + counterterm ansatz for the third moment. Non-cosmological parameters: bias (b1, b2, bs, third order set to zero), one counterterm per multipole, two stochastic terms (constant + k^2 mu^2). The counterterm ansatz set to zero because it is degenerate with the two multipole counterterms. 0.12 Model description in arXiv:2005.00523, challenge results in arXiv:2012.04636 July 11th 2020 Yes
REPT: EPT with IR-resummation based on wiggle/no-wiggle split. Bias choice same as the above (third-order bias assumed to correspond to zero Lagrangian bias) 0.12
Shi-Fan Chen, Zvonimir Vlah, Emanuele Castorina, Martin White LPT 1-loop, full IR resummation of both displacements and velocities 0.12 arXiv:2012.04636 Dec 3rd 2020 No
Yosuke Kobayashi (w/ Takahiro Nishimichi and Masahiro Takada) Halo-model based emulator with a HOD prescription to connect to galaxies 0.2 Model described in arXiv:2005.06122, challenge results to be described in a separate paper April 2nd 2021 Yes (Ground-truth values blinded only to Y. Kobayashi, who conducted all the analysis)
