Shape-Preserving Evolution of the Global Ultraviolet Quasar Luminosity Function to
Wenjie Wang, Zunli Yuan, Yu Luo +1
We present a global unbinned-likelihood analysis of the rest-frame ultraviolet (UV) quasar luminosity function (QLF) over , using a final analysis sample of 70,960…
Revisiting the 150 MHz Radio Luminosity Function of Star-Forming Galaxies with LOFAR Deep Fields through a Refined Statistical Framework
Wenjie Wang, Zunli Yuan, Hongwei Yu +3
We present a comprehensive analysis of the 150~MHz radio luminosity function (LF) of star-forming galaxies (SFGs) using deep observations from the LOFAR Two-metre Sky Survey in the…
Comparative analysis of missing data imputation methods for CSST survey: Impact on photometric redshift estimation performance
Ling Wang, Zhu Chen, Zhijian Luo +42
Improving the accuracy of photometric redshifts (photo-) is essential for reliable statistical studies of cosmology and galaxy evolution. However, missing photometric bands are…
Mock Observations for the CSST Mission: Main Surveys -- the Mock Catalogue
Cheng-Liang Wei, Yu Luo, Hao Tian +17
The Chinese Space Station Survey Telescope (CSST) is a flagship space mission, designed to carry out a large-area sky survey to explore the nature of dark matter and dark energy in…
Modeling the impacts of galaxy intrinsic alignments on weak lensing peak statistics
Tianyu Zhang, Xiangkun Liu, Ziwei Li +5
Weak gravitational lensing (WL) peak statistics capture cosmic non-linear structures and can provide additional cosmological information complementary to cosmic shear two-point cor…
Intermediate Mass Ratio Inspirals in Milky Way Galaxies
Jillian Bellovary, Yuantong Luo, Thomas Quinn +3
A consequence of a non-zero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merg…
