Compton hump reverberation lag in the bright Seyfert 1 galaxy IC 4329A with NuSTAR

Samuzal Barua, Hengxiao Guo, Minfeng Gu +1

Recent reverberation delay measurements have moved beyond the 10 keV X-ray range, providing evidence for the Compton hump (a.k.a. reflection hump) in the lag spectra. We report the…

Antarctic TianMu Staring Observation Project I: Overview and Implementation of the Prototype Telescope

Dan Zhou, Jing Zhong, Jianchun Shi +31

Wide-field rapid sky surveys serve as critical observational methods for time-domain astronomical research. The Antarctic region, with several months of continuous dark nights annu…

The Intermediate-Mass Black Hole Reverberation Mapping Project: First Detection of Mid-Infrared Lags in Prototypical IMBHs in NGC 4395 and POX 52

Jingbo Sun, Hengxiao Guo, Wenwen Zuo +25

The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding black hole seeding process and the formation of supermassive black holes in the…

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…

Multiband Optical Variability of the Blazar 3C 454.3 on Diverse Timescales

Karan Dogra, Alok C. Gupta, C. M. Raiteri +79

Due to its peculiar and highly variable nature, the blazar 3C 454.3 has been extensively monitored by the WEBT team. Here, we present for the first time these long-term optical flu…

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…
