Super-sample covariance of the thermal Sunyaev-Zel'dovich effect
First, we study the impact of super sample covariance (SSC) on the tSZ power spectrum measurements, and find that the sample variance is dominated by the connected non-Gaussian (cNG) covariance arising mainly from Poisson number fluctuations of massive clusters in the survey volume.

Testing Stochastic Gravitational Wave Signals from Primordial Black Holes with Optical Telescopes
Primordial black holes (PBHs) can constitute the predominant fraction of dark matter (DM) if PBHs reside in the currently unconstrained "sublunar" mass range.

Power Spectrum of Intrinsic Alignments of Galaxies in IllustrisTNG
The shape of massive disk- and spheroid-galaxies tend to align with the tidal field.

Impacts of pre-initial conditions on anisotropic separate universe simulations: a boosted tidal response in the epoch of reionization
To generate initial conditions for cosmological $N$-body simulations, one needs to prepare a uniform distribution of simulation particles, so-called the pre-initial condition (pre-IC).

Blinded challenge for precision cosmology with large-scale structure: results from effective field theory for the redshift-space galaxy power spectrum
An accurate theoretical template for the galaxy power spectrum is a key for the success of ongoing and future spectroscopic surveys.

Joint likelihood function of cluster counts and $n$-point correlation functions: Improving their power through including halo sample variance
This approach enables an approximate derivation of a joint likelihood for the cluster number counts, the weak lensing power spectrum and the bispectrum.

Calibrating the Nonlinear Matter Power Spectrum: Requirements for Future Weak Lensing Surveys
We estimate the accuracy with which the matter power spectrum will need to be calibrated in order not to contribute appreciably to the error budget for future weak lensing surveys.
