Detecting Intermediate-mass Black Holes Using Quasar Microlensing
Zihao Wu, Luis C. Ho
Recent studies suggest that numerous intermediate-mass black holes (IMBHs) may wander undetected across the Universe, emitting little radiation. These IMBHs largely preserve their…
From Non-Detection to Detection: Atacama Compact Array Mosaic Observations of Faint Extended [C I] Emission in NGC 7679
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +8
We report the detection of [C I] -- emission in the nearby galaxy NGC 7679 using the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array (…
The Detection Rate of Associated \mgii\ Absorption Lines in Quasars Depends on Their Radio Emission
Chen ZF, Luis C. Ho
In active galactic nuclei, jet-driven feedback plays a significant role in influencing the properties of gas within their host galaxy and the circumgalactic medium. By combining ob…
A Dual Active Black Hole Candidate with Mass Ratio ~7:1 in a Disk Galaxy
Xiao Cao, Yan-Mei Chen, Yong Shi +8
Dual active galactic nuclei (AGNs) with comparable masses are commonly witnessed among the major merged galaxies with interaction remnants. Considering almost every massive galaxy…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…
Ordered magnetic fields around the 3C 84 central black hole
G. F. Paraschos, J. -Y. Kim, M. Wielgus +279
3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…
X-Ray Constraints on the Hot Gaseous Corona of Edge-on Late-type Galaxies in Virgo
Meicun Hou, Lin He, Zhensong Hu +6
We present a systematic study of the putative hot gas corona around late-type galaxies (LTGs) residing in the Virgo cluster, based on archival Chandra observations. Our sample cons…
First Sagittarius A* Event Horizon Telescope Results. V. Testing Astrophysical Models of the Galactic Center Black Hole
The Event Horizon Telescope Collaboration
In this paper, we provide a first physical interpretation for the Event Horizon Telescope (EHT)'s 2017 observations of Sgr A*. Our main approach is to compare resolved EHT data at…
Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: the Low-luminosity Cases and an Application to Sgr A
J. -M. Wang, J. -R. Liu, Y. -R. Li +3
In this paper, we investigate the astrophysical processes of stellar-mass black holes (sMBHs) embedded in advection-dominated accretion flows (ADAFs) of supermassive black holes (S…
Black holes regulate cool gas accretion in massive galaxies
Tao Wang, Ke Xu, Yuxuan Wu +10
The nucleus of almost all massive galaxies contains a supermassive black hole (BH). The feedback from the accretion of these BHs is often considered to have crucial roles in establ…
ReveaLLAGN 0: First Look at JWST MIRI data of Sombrero and NGC 1052
K. Goold, A. Seth, M. Molina +28
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGN. We focus on two observations with th…
The Sloan Digital Sky Survey Reverberation Mapping Project: Accretion-Disk Sizes from Continuum Lags
Y. Homayouni, Jonathan R. Trump, C. J. Grier +12
We present accretion-disk structure measurements from continuum lags in the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Lags are measured using the \texttt{JA…
