Bipolar blobs as evidence of hidden AGN activities in the low-mass galaxies
Yao Yao, Enci Wang, Zhicheng He +4
We report the evidence of a hidden black hole (BH) in a low-mass galaxy, MaNGA 9885-9102, and provide a new method to identify active BH in low mass galaxies. This galaxy is origin…
Exploring the origin of cold gas and star formation in a rare population of strongly bulge-dominated early-type Galaxies
Fujia Li, Enci Wang, Ming Zhu +7
We analyze the properties of a rare population, the strongly bulge-dominated early-type galaxies (referred to as sBDEs) with significant HI gas, using the databases from the FAST A…
Galaxy Group Ellipticity Confirms a Younger Cosmos
Yu Rong
We present an analysis of the ellipticities of galaxy groups, derived from the spatial distribution of member galaxies, revealing a notable incongruity between the observed local g…
Gas-rich Ultra-diffuse Galaxies Are Originated from High Specific Angular Momentum
Yu Rong, Huijie Hu, Min He +5
Ultra-diffuse galaxies, characterized by comparable effective radii to the Milky Way but possessing 100-1,000 times fewer stars, offer a unique opportunity to garner novel insights…
Galaxy Triplets Alignment in Large-scale Filaments
Yu Rong, Jinzhi Shen, Zichen Hua
Leveraging the datasets of galaxy triplets and large-scale filaments obtained from the Sloan Digital Sky Survey, we scrutinize the alignment of the three sides of the triangles for…
