SMMAN Studies of AGN Variability. I. Long-term Spectral Evolution and a Candidate -day Quasi-periodic Modulation in 4C+72.28

Xin Wang, Timur Mufakharov, Guiping Tan +6

The SMMAN project has carried out nine years of radio flux monitoring in the C and K bands of the blazar 4C+72.28. The two bands show markedly different secular evolution, with a s…

Constraints on the Intranight Optical Variability of Intermediate-Mass Black Hole Candidates

Wenwen Zuo, Hengxiao Guo, Wanling Liu +12

Intermediate-mass black holes (IMBHs) provide a unique regime for studying accretion variability at the low-mass end of the black hole population, yet their intranight optical vari…

A Wandering 35,000-Solar-Mass Black Hole Fed by a Gravitational Wake

Xin Li, Yong Shi, Fuyan Bian +8

Intermediate-mass black holes are widely considered to be the seeds of supermassive black holes, a substantial population of which is expected to remain displaced from galactic nuc…

Thermal Effects on the Moment of Inertia and Gravitational Redshift of PSR J1012+5307: Implications for Hyperonic Matter under SU(3) and SU(6) Symmetries

Y. Xu, X. L. Huang, Y. B. Wang +5

The temperature dependence of neutron star structure significantly alters the equation of state, thereby affecting observable properties such as the moment of inertia and gravitati…

Observational Study of Multi-wavelength Synergistic Effects in 3C 120

Yuting He, Ming Zhang, Qi Yuan +1

The energy dissipation and particle acceleration mechanisms within relativistic jets remain fundamental questions in active galactic nuclei (AGN) research. In this paper, we presen…

AT2021aeuk: A Repeating Partial Tidal Disruption Event Candidate in a Narrow-line Seyfert 1 galaxy

Jingbo Sun, Hengxiao Guo, Minfeng Gu +13

A black hole (BH) can tear apart a star that ventures within its tidal radius, producing a luminous flare as the stellar debris falls back, known as a tidal disruption event (TDE).…

First Detection of Radio Emission from the Intermediate Mass Black Hole in POX 52: Deep Multi-Band Observations with ATCA and VLA

Qi Yuan, Hengxiao Guo, Minfeng Gu +14

We present the first multi-band centimeter detection of POX 52, a nearby dwarf galaxy believed to habor a robust intermediate mass black hole (IMBH). We conducted the deep observat…

The angular momentum of stars reflects the relationship between star-forming environment and galactic evolution history

Yu-Fu Shen, Yan Xu, Yi-Bo Wang +3

This study focuses on stars with masses above the Kraft break in the \textit{Kepler} field. Their rotational angular momenta are essentially the same as those at the zero-age main…

Spectral Energy Distribution Variability of the Blazar OJ 287 during 2009-2021

Wenwen Zuo, Alok C. Gupta, Minfeng Gu +11

Using nearly simultaneous radio, near-infrared, optical, and ultraviolet data collected since 2009, we constructed 106 spectral energy distributions (SEDs) of the blazar OJ 287. Th…

Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy

Wenwen Zuo, Hengxiao Guo, Jingbo Sun +25

To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, mul…
