DESI Legacy Imaging Surveys Data Release 9: Cosmological Constraints from Galaxy Clustering and Weak Lensing using the Minimal Bias Model
Haojie Xu, Hekun Li, Jun Zhang +11
We present a tentative constraint on cosmological parameters and from a joint analysis of galaxy clustering and galaxy-galaxy lensing from DESI Legacy Imaging Surveys D…
The physical properties of massive green valley galaxies as a function of environments at in 3D-\textit{HST}/CANDELS fields
Wenjun Chang, Guanwen Fang, Yizhou Gu +3
To investigate the effects of environment in the quenching phase, we study the empirical relations for green valley (GV) galaxies between overdensity and other physical properties…
Halo Properties and Mass Functions of Groups/Clusters from the DESI Legacy Imaging Surveys DR9
Jiaqi Wang, Xiaohu Yang, Jun Zhang +16
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model the group-galax…
Automatic morphological classification of galaxies: convolutional autoencoder and bagging-based multiclustering model
C. C. Zhou, Y. Z. Gu, G. W. Fang +1
In order to obtain morphological information of unlabeled galaxies, we present an unsupervised machine-learning (UML) method for morphological classification of galaxies, which can…
