ASKAP discovery of a pair of large radio bubbles: on the origin of odd radio circles
Renzhi Su, Minfeng Gu, Hengxiao Guo +9
We report the serendipitous discovery of a large, low-surface-brightness radio bubble in 944 MHz continuum data from the ASKAP Evolutionary Map of the Universe (EMU) survey. The st…
XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region
E. Kammoun, T. Kawamuro, K. Murakami +48
We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…
Fast inflowing ionized absorber tracing the gas dynamics at sub-parsec scale around Mrk 3
Fangzheng Shi, Matteo Guainazzi, Yijun Wang
Accretion onto supermassive black hole (SMBH) can release energy via radiation, jets or winds, providing feedback effects on the circumnuclear gas environment. However, not all act…
Observational Evidence for Hot Wind Impact on pc-scale in Low-luminosity Active Galactic Nucleus
Fangzheng Shi, Feng Yuan, Zhiyuan Li +2
Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow…
Variable ionized disk wind in MAXI J1803-298 revealed by NICER
Zuobin Zhang, Cosimo Bambi, Honghui Liu +7
We present the results from the NICER observation data of MAXI J1803-298 across the entire 2021 outburst. In the intermediate and soft state, we detect significant absorption lines…
Scientific Objectives of the Hot Universe Baryon Surveyor (HUBS) Mission
Joel Bregman, Renyue Cen, Yang Chen +51
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spa…
Black Hole Feeding and Feedback in a Compact Galaxy
Yihuan Di, Yuan Li, Feng Yuan +2
We perform high-resolution hydrodynamical simulations using the framework of {\it MACER} to investigate supermassive black hole (SMBH) feeding and feedback in a massive compact gal…
Evidence for A Hot Wind from High-resolution X-ray Spectroscopic Observation of the Low-luminosity Active Galactic Nucleus in NGC 7213
Fangzheng Shi, Bocheng Zhu, Zhiyuan Li +1
Super-massive black holes (SMBHs) spend most of their lifetime accreting at a rate well below the Eddington limit, manifesting themselves as low-luminosity active galactic nuclei (…
Investigating the Accretion Nature of Binary Supermassive Black Hole Candidate SDSS J025214.67-002813.7
Adi Foord, Xin Liu, Kayhan Gültekin +3
We present results on a multi-wavelength analysis of SDSS J025214.67-002813.7, a system which has been previously classified as a binary AGN candidate based on periodic signals det…
An Energetic Hot Wind from the Low-luminosity Active Galactic Nucleus M81*
Fangzheng Shi, Zhiyuan Li, Feng Yuan +1
For most of their lifetime, super-massive black holes (SMBHs) commonly found in galactic nuclei obtain mass from the ambient at a rate well below the Eddington limit, which is medi…
Multi-epoch analysis of the X-ray spectrum of the active galactic nucleus in NGC 5506
Shangyu Sun, Matteo Guainazzi, Qingling Ni +5
We present a multi-epoch X-ray spectroscopy analysis of the nearby narrow-line Seyfert I galaxy NGC 5506. For the first time, spectra taken by Chandra, XMM-Newton, Suzaku, and NuST…
