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…

Quasar winds caught on acceleration and deceleration

Weimin Yi, P. B. Hall, Zunlin Yuan +5

We present an observational study of wind acceleration based on four low-ionization broad absorption line (LoBAL) quasars (J0136, J1238, J1259, J1344). J0136 and J1344 (group-1) ar…

Discovery of spectacular quasar-driven superbubbles in red quasars

Lu Shen, Guilin Liu, Zhicheng He +7

Quasar-driven outflows on galactic scales are a routinely invoked ingredient for galaxy formation models. We report the discovery of ionized gas nebulae as traced by [O III] 500…

Compressed Interaction Graph based Framework for Multi-behavior Recommendation

Wei Guo, Chang Meng, Enming Yuan +8

Multi-types of user behavior data (e.g., clicking, adding to cart, and purchasing) are recorded in most real-world recommendation scenarios, which can help to learn users' multi-fa…

A Survey on User Behavior Modeling in Recommender Systems

Zhicheng He, Weiwen Liu, Wei Guo +4

User Behavior Modeling (UBM) plays a critical role in user interest learning, which has been extensively used in recommender systems. Crucial interactive patterns between users and…

Evidence for the connection between star formation rate and evolutionary phases of quasars

Zhifu Chen, Zhicheng He, Luis C. Ho +5

Both theory and observations suggest that outflows driven by an active central supermassive black hole (SMBH) has a feedback effect on shaping the global properties of the host gal…
