The physical mechanism for two rapid changing-look AGNs: SDSS J0225+0030 and SDSS J1723+5504
Shuang-Liang Li, Xinwu Cao, Wei-Min Gu
SDSS J0225+0030 and SDSS J1723+5504 are two turn-on changing-look active galactic nuclei (CL AGNs) with transition timescales shorter than one year. Such short timescales pose a ch…
Little Red Dots as Supermassive Counterparts of SS 433: A Hyper-Eddington Accretion Framework
Shuying Zhou, Mouyuan Sun, Xihan Ji +11
High-redshift little red dots (LRDs) are compact sources characterized by V-shaped spectral energy distributions (SEDs), broad emission lines, and often prominent Balmer breaks. Th…
Magnetized Accretion Disks with Outflows for Changing-look AGNs
Wen-Biao Wu, Wei-Min Gu
Changing-look active galactic nuclei (CL-AGNs) challenges the standard accretion theory owing to its rapid variability. Recent numerical simulations have shown that, for the sub-Ed…
Black Hole Accretion with Saturated Magnetic Pressure and Disk Wind
Jiahui Huang, Hua Feng, Wei-Min Gu +1
We construct an analytical black hole accretion disk model that incorporates both magnetic pressure and disk wind, which are found to be important from numerical simulations. A sat…
Searching for Compact Object Candidates from LAMOST Time-Domain Survey of Four K2 Plates
Senyu Qi, Wei-Min Gu, Tuan Yi +3
The time-domain (TD) surveys of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) yield high-cadence radial velocities, paving a new avenue to study binary sys…
Bubble in the Whale: Identifying the Optical Counterparts and Extended Nebula for the Ultraluminous X-ray Sources in NGC 4631
Jing Guo, Jianfeng Wu, Hua Feng +9
We present a deep optical imaging campaign on the starburst galaxy NGC 4631 with CFHT/MegaCam. By supplementing the HST/ACS and Chandra/ACIS archival data, we search for the optica…
