Mock Observations for the CSST Mission: Multi-Channel Imager--The Cluster Field
Yushan Xie, Xiaokai Chen, Shuai Feng +20
The Multi-Channel Imager (MCI), one of the instruments aboard the China Survey Space Telescope (CSST), is designed to simultaneously observe the sky in three filters, covering wave…
CURLING -- II. Improvement on the Inference from Pixelized Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Yiping Shu +9
Strongly lensed supernovae (glSNe) provide a powerful, independent method to measure the Hubble constant, , through time delays between their multiple images. The accuracy o…
UPdec-Webb: A Dataset for Coaddition of JWST NIRCam Images
Lei Wang, Huanyuan Shan, Lin Nie +19
We present the application of the image coaddition algorithm, Up-sampling and PSF Deconvolution Coaddition (UPDC), for stacking multiple exposure images captured by the James Webb…
Detection Rate of Galaxy Cluster Lensed Stellar Binary Black Hole Mergers by the Third-generation Gravitational Wave Detectors
Zhiwei Chen, Yushan Xie, Youjun Lu +4
Gravitational waves (GWs) from stellar binary black hole (sBBH) mergers can be strongly gravitational lensed by intervening galaxies/galaxy clusters. Only a few works investigated…
CURLING - I. The Influence of Point-like Image Approximation on the Outcomes of Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Nan Li +11
Cluster-scale strong lensing is a powerful tool for exploring the properties of dark matter and constraining cosmological models. However, due to the complex parameter space, pixel…
How to coadd images: II. Anti-aliasing and PSF deconvolution
Lei Wang, Huanyuan Shan, Lin Nie +8
We have developed a novel method for co-adding multiple under-sampled images that combines the iteratively reweighted least squares and divide-and-conquer algorithms. Our approach…
Influence of sources with a spectral peak in the detection of Cosmic Dawn and Epoch of Reionization
Mengfan He, Qian Zheng, Quan Guo +5
Foreground removal is one of the biggest challenges in the detection of the Cosmic Dawn (CD) and Epoch of Reionization (EoR). Various foreground subtraction techniques have been de…
HybPSF: Hybrid PSF reconstruction for the observed JWST NIRCam image
Lin Nie, Huanyuan Shan, Guoliang Li +6
The James Webb Space Telescope (JWST) ushers in a new era of astronomical observation and discovery, offering unprecedented precision in a variety of measurements such as photometr…
Assessing Mass Loss and Stellar-to-Halo Mass Ratio of Satellite Galaxies: A Galaxy-Galaxy Lensing Approach Utilizing DECaLS DR8 Data
Chunxiang Wang, Ran Li, Huanyuan Shan +9
The galaxy-galaxy lensing technique allows us to measure the subhalo mass of satellite galaxies, studying their mass loss and evolution within galaxy clusters and providing direct…
MaNGA DynPop -- IV. Stacked total density profile of galaxy groups and clusters from combining dynamical models of integral-field stellar kinematics and galaxy-galaxy lensing
Chunxiang Wang, Ran Li, Kai Zhu +9
We present the measurement of total and stellar/dark matter decomposed mass density profile around a sample of galaxy groups and clusters with dynamical masses derived from integra…
