Local Group Dwarf Galaxy Detection Limit in the CSST survey
Han Qu, Zhen Yuan, Amandine Doliva-Dolinsky +9
We predict the dwarf galaxy detection limits for the upcoming Chinese Space Station Telescope (CSST) survey that will cover 17,500 deg of the sky with a wide field of view of…
Effects of galaxy intrinsic alignment on weak lensing peak statistics
Tianyu Zhang, Xiangkun Liu, Chengliang Wei +4
The galaxy intrinsic alignment (IA) is a dominant source of systematics in weak lensing (WL) studies. In this paper, by employing large simulations with semi-analytical galaxy form…
The spherical Fast Multipole Method (sFMM) for Gravitational Lensing Simulation
Xingpao Suo, Xi Kang, Chengliang Wei +1
In this paper, we present a spherical Fast Multipole Method (sFMM) for ray tracing simulation of gravitational lensing (GL) on a curved sky. The sFMM is a non-trivial extension of…
Towards Super-resolution via Iterative multi-exposure Coaddition
Lei Wang, Guoliang Li, Xi Kang
In this article, we provide an alternative up-sampling and PSF deconvolution method for the iterative multi-exposure coaddition. Different from the previous works, the new method h…
Wave effect of gravitational waves intersected with a microlens field: a new algorithm and supplementary study
Xikai Shan, Guoliang Li, Xuechun Chen +2
The increase in gravitational wave (GW) events has allowed receiving strong lensing image pairs of GWs. However, the wave effect (diffraction and interference) due to the microlens…
Tolerance For the Pixelation Effect in Shear Measurement
Zhi Shen, Jun Zhang, Hekun Li +6
Images taken by space telescopes typically have a superb spatial resolution, but a relatively poor sampling rate due to the finite CCD pixel size. Beyond the Nyquist limit, it beco…
