The spin measurement of MAXI J1348-630 using the Insight-HXMT data
Yujia Song, Nan Jia, Jun Yang +3
We report the results of fitting Insight-HXMT data to the black hole X-ray binary MAXI J1348-430, which was discovered on January 26th, 2019, with the Gas Slit Camera (GSC) on-boar…
Cosmological constraints from HSC survey first-year data using deep learning
Tianhuan Lu, Zoltán Haiman, Xiangchong Li
We present cosmological constraints from the Subaru Hyper Suprime-Cam (HSC) first-year weak lensing shear catalogue using convolutional neural networks (CNNs) and conventional summ…
Comparing weak lensing peak counts in baryonic correction models to hydrodynamical simulations
Max E. Lee, Tianhuan Lu, Zoltán Haiman +2
Next-generation weak lensing (WL) surveys, such as by the Vera Rubin Observatory's LSST, the Space Telescope, and the space mission, will supply…
Simultaneously constraining cosmology and baryonic physics via deep learning from weak lensing
Tianhuan Lu, Zoltán Haiman, José Manuel Zorrilla Matilla
Ongoing and planned weak lensing (WL) surveys are becoming deep enough to contain information on angular scales down to a few arcmin. To fully extract information from these small…
Cosmological Constraints from Weak Lensing Peaks: Can Halo Models Accurately Predict Peak Counts?
Alina Sabyr, Zoltán Haiman, José Manuel Zorrilla Matilla +1
In order to extract full cosmological information from next-generation large and high-precision weak lensing (WL) surveys (e.g. Euclid, Roman, LSST), higher-order statistics that p…
The Impact of Baryons on Cosmological Inference from Weak Lensing Statistics
Tianhuan Lu, Zoltán Haiman
As weak lensing surveys are becoming deeper and cover larger areas, information will be available on small angular scales down to the arcmin level. To extract this extra informatio…
The matter fluctuation amplitude inferred from the weak lensing power spectrum and correlation function in CFHTLenS data
Tianhuan Lu, Zoltán Haiman
Based on the cosmic shear data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), Kilbinger et al. (2013) obtained a constraint on the amplitude of matter fluctuati…
Removing the Impact of Correlated PSF Uncertainties in Weak Lensing
Tianhuan Lu, Jun Zhang, Fuyu Dong +5
Accurate reconstruction of the spatial distributions of the Point Spread Function (PSF) is crucial for high precision cosmic shear measurements. Nevertheless, current methods are n…
An accurate centroid algorithm for PSF reconstruction
Tianhuan Lu, Wentao Luo, Jun Zhang +8
In this work, we present a novel centroiding method based on Fourier space Phase Fitting(FPF) for Point Spread Function(PSF) reconstruction. We generate two sets of simulations to…
Galaxy-galaxy weak-lensing measurement from SDSS: II. host halo properties of galaxy groups
Wentao Luo, Xiaohu Yang, Tianhuan Lu +10
As the second paper of a series on studying galaxy-galaxy lensing signals using the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modelling of…
ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
Revealing the cosmic web dependent halo bias
Xiaohu Yang, Youcai Zhang, Tianhuan Lu +7
Halo bias is the one of the key ingredients of the halo models. It was shown at a given redshift to be only dependent, to the first order, on the halo mass. In this study, four typ…
Testing PSF Interpolation In Weak Lensing With Real Data
Tianhuan Lu, Jun Zhang, Fuyu Dong +5
Reconstruction of the point spread function (PSF) is a critical process in weak lensing measurement. We develop a real-data based and galaxy-oriented pipeline to compare the perfor…
