Optimization of Tessellation-based Statistics: Void Statistics
Yu Liu, Cheng Zhao, Yu Yu +2
Tessellation methods are extensively employed in the analyses of cosmic large-scale structure (LSS). However, these techniques are highly sensitive to perturbations in both densiti…
Advancing weak lensing mass mapping with a mask-aware HEALPix transformer
Yihe Wang, Yu Yu
We present HEALFormer, a transformer-based neural network architecture for weak gravitational lensing mass mapping that reconstructs convergence maps from incomplete and noisy shea…
Redshift Distributions of Fast Radio Bursts Inferred Using Clustering in Dispersion Measure Space
Hui Peng, Yu Yu
Fast radio bursts (FRBs), millisecond-duration radio transient events, possess the potential to serve as excellent cosmological probes. The FRB redshift distribution contains infor…
Reconstructing redshift distributions with photometric galaxy clustering
Hui Peng, Yu Yu
The accurate determination of the true redshift distributions in tomographic bins is critical for cosmological constraints from photometric surveys. The proposed redshift self-cali…
Accurate Power Spectrum Estimation toward Nyquist limit
Yipeng Wang, Yu Yu
The power spectrum, as a statistic in Fourier space, is commonly numerically calculated using the fast Fourier transform method to efficiently reduce the computational costs. To al…
