SBi3PCF: cosmology with Dark Energy Survey Year 3 cosmic shear
David Gebauer, Anik Halder, Zhengyangguang Gong +1
We present the first cosmic shear data analysis of the integrated 3-point correlation function (i3PCF), a higher-order weak lensing statistic, and the first simulation-based infere…
Probing Parity Violation with Weak Lensing Trispectrum
Sijin Chen, Zhengyangguang Gong, Jiamin Hou
We establish the weak gravitational lensing convergence trispectrum as an independent probe of cosmological parity violation in the late-time Large-Scale Structure (LSS). To map th…
C3NN-SBI: Learning Hierarchies of -Point Statistics from Cosmological Fields with Physics-Informed Neural Networks
Kai Lehman, Zhengyangguang Gong, David Gebauer +2
Cosmological analyses are moving past the well understood 2-point statistics to extract more information from cosmological fields. A natural step in extending inference pipelines t…
Clustering of the extreme: A theoretical description of weak lensing critical points power spectra in the mildly nonlinear regime
Zhengyangguang Gong, Alexandre Barthelemy, Sandrine Codis
In cosmic web analysis, complementary to traditional cosmological probes, the extrema (e.g. peaks and voids) two-point correlation functions (2PCFs) are of particular interest for…
C3NN: Cosmological Correlator Convolutional Neural Network -- an interpretable machine learning tool for cosmological analyses
Zhengyangguang Gong, Anik Halder, Annabelle Bohrdt +2
Modern cosmological research in large scale structure has witnessed an increasing number of applications of machine learning methods. Among them, Convolutional Neural Networks (CNN…
Making the leap I: Modelling the reconstructed lensing convergence PDF from cosmic shear with survey masks and systematics
Alexandre Barthelemy, Anik Halder, Zhengyangguang Gong +1
The last few years have seen the development of a promising theoretical framework for statistics of the cosmic large-scale structure -- the theory of large deviations (LDT) for mod…
Beyond 32-point cosmology: the integrated shear and galaxy 3-point correlation functions
Anik Halder, Zhengyangguang Gong, Alexandre Barreira +3
We present the integrated 3-point correlation functions (3PCF) involving both the cosmic shear and the galaxy density fields. These are a set of higher-order statistics that descri…
Cosmology from the integrated shear 3-point correlation function: simulated likelihood analyses with machine-learning emulators
Zhengyangguang Gong, Anik Halder, Alexandre Barreira +2
The integrated shear 3-point correlation function measures the correlation between the local shear 2-point function and the 1-point shear aperture mass in patch…
"The Goose" Pulsar Wind Nebula of PSR J1016-5857: The Birth of a Plerion
Noel Klingler, Oleg Kargaltsev, George G. Pavlov +3
We report the results of X-ray (CXO) and radio (ATCA) observations of the pulsar wind nebula (PWN) powered by the young pulsar PSR J1016--5857, which we dub "the Goose" PWN. In bot…
