Intrinsic Alignments in Redshift Space I: Symmetries

Kazuyuki Akitsu, Shi-Fan Chen, Zvonimir Vlah

Galaxy shapes are unique tensor tracers of large-scale structure, providing a promising avenue to both enhance current cosmological programs and detect new physics beyond the scala…

A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics

2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23

The paper presents the first results of the "Beyond-2pt" community data challenge, where participants used various beyond‑two‑point galaxy clustering methods on high‑precision mock…

Lyman-Alpha Forest and its Cross-Correlation with High-Redshift Galaxies in Effective Field Theory at the Field Level

Roger de Belsunce, Mikhail M. Ivanov, James M. Sullivan +2

We present a field-level perturbative forward model for the Lyman-alpha (Lya) forest flux decrement. We validate it on two simulation suites: large-volume AbacusSummit N-body simul…

Blue-tilted Runnings and the JWST Early Galaxy Tension

Mikage U. Kobayashi, Gen Chiaki, Kazutaka Kimura +4

The recent James Webb Space Telescope (JWST) observations reported the unexpectedly large abundance of massive galaxies with stellar masses of at high reds…

Galaxy sizes as complementary (zero-)bias tracers of local primordial non-Gaussianity

Nhat-Minh Nguyen, Kazuyuki Akitsu, Atsushi Taruya

The scale-dependent bias in halo and galaxy power spectra is a key signature of local primordial non-Gaussianity (local PNG), with PNG sensitivity scaling as -- the rati…

Equilateral non-Gaussian Bias at the Field Level

Divij Sharma, James M. Sullivan, Kazuyuki Akitsu +1

Primordial non-Gaussianity (PNG) is a common prediction of a wide class of inflationary models. Equilateral-type PNG, generically predicted by single-field inflationary models with…
