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…
AGN lifetimes in UV-selected galaxies: a clue to supermassive black hole-host galaxy coevolution
Xiaozhi Lin, Yongquan Xue, Guanwen Fang +3
The coevolution between supermassive black holes (SMBHs) and their host galaxies has been proposed for more than a decade, albeit with little direct evidence about black hole accre…
Morphological Transformation and Star Formation Quenching of Massive Galaxies at 0.5 < z < 2.5 in 3D-HST/CANDELS
Shuang Liu, Yizhou Gu, Qirong Yuan +4
To figure out the effect of stellar mass and local environment on morphological transformation and star formation quenching in galaxies, we use the massive ($M_* \geq 10^{10} M_{\o…
The effect of environment on star formation activity and morphology at 0.5 < z < 2.5 in CANDELS
Yizhou Gu, Guanwen Fang, Qirong Yuan +2
To explore the effect of environment on star-formation and morphological transformation of high-redshift galaxies, we present a robust estimation of localized galaxy overdensity us…
The effect of the morphological quenching mechanism on star formation activity at 0.5 < z < 1.5 in 3D-HST/CANDELS
Shiying Lu, Guanwen Fang, Yizhou Gu +3
Several mechanisms for the transformation of blue star-forming to red quiescent galaxies have been proposed, and the green valley (GV) galaxies amid them are widely accepted in a t…
Estimating lifetimes of uv-selected massive galaxies at in the cosmos/ultravista field through clustering analyses
Xiaozhi Lin, Guanwen Fang, Yongquan Xue +2
We present an estimation of lifetimes of massive galaxies with distinct UV colors at in the COSMOS/UltraVISTA field. After dividing the galaxy sample into subsa…
