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…

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…

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…
