Enhancing Photometric Redshift Estimation for LSST with a Hybrid LSTM-Mixture Density Network
Zhijian Luo, Yangyang Li, Xinyu Luo +4
Accurate photometric redshift (photo-) estimation and robust uncertainty quantification are essential for the LSST to achieve its precision cosmology goals. Traditional machine…
Cross-Comparison of Galaxies Detected in the CSST Spectroscopic Survey and the SKA HI Survey
Yingfeng Liu, Furen Deng, Wenxiang Pei +8
We present a forward-modeling framework to forecast the galaxies detected in the Chinese Space Station Survey Telescope (CSST) spectroscopic survey and the Square Kilometre Array (…
Revised AGN Spectral Model Reveals a More Significant Role in Cosmic Reionization
Tong Su, Qi Guo, Wenxiang Pei +1
Reionization marks one of the most important phase transitions in the history of the Universe, during which neutral baryonic matter was transformed into ionized plasma. While star-…
A semi-analytical mock galaxy catalog for the CSST extragalactic surveys from the Jiutian simulations
Zhenlin Tan, Lizhi Xie, Jiaxin Han +17
We introduce a mock galaxy catalog built for the CSST extragalactic surveys using the primary runs of the Jiutian -body simulation suites. The catalogs are built by coupling the…
Identifying Dust-lane Spheroidal Galaxies in DESI Legacy Imaging Surveys Using Semi-Supervised Methods
Zhijian Luo, Jianzhen Chen, Wenxiang Pei +4
Dust-lane spheroidal galaxies (DLSGs) are unique astrophysical systems that exhibit the morphology of early-type galaxies (ETGs) but are distinguished by prominent dust lanes. Rece…
Modeling the Spectral Energy Distribution of Active Galactic Nuclei: Implications for Cosmological Simulations of Galaxy Formation
Tong Su, Qi Guo, Erlin Qiao +3
Modeling the spectral energy distribution (SED) of active galactic nuclei (AGN) plays a very important role in constraining modern cosmological simulations of galaxy formation. Her…
Photometric properties of classical bulge and pseudo-bulge galaxies at
Jia Hu, Qifan Cui, Lan Wang +2
We compare the photometric properties and specific star formation rate (sSFR) of classical and pseudo-bulge galaxies with at , select…
Effectiveness of halo and galaxy properties in reducing the scatter in the stellar-to-halo mass relation
Wenxiang Pei, Qi Guo, Shi Shao +2
The stellar-to-halo mass relation (SHMR) is a fundamental relationship between galaxies and their host dark matter haloes. In this study, we examine the scatter in this relation fo…
Simulating emission line galaxies for the next generation of large-scale structure surveys
Wenxiang Pei, Qi Guo, Ming Li +8
We investigate emission line galaxies across cosmic time by combining the modified L-Galaxies semi-analytical galaxy formation model with the JiuTian cosmological simulation. We im…
A younger Universe implied by satellite pair correlations from SDSS observations of massive galaxy groups
Qing Gu, Qi Guo, Marius Cautun +5
Many of the satellites of galactic-mass systems such as the Miky Way, Andromeda and Centaurus A show evidence of coherent motions to a larger extent than most of the systems predic…
