Reverberation Evidence for Stream Collision and Delayed Disk Formation in Tidal Disruption Events by Hengxiao Guo, Jingbo Sun, Shuangliang Li, Yan-Fei Jiang, Tinggui Wang, Defu Bu, Ning Jiang, Yanan Wang, Yuhan Yao, Rongfeng Shen, Minfeng Gu, Mouyuan Sun

“…In contrast, the model of stream collisions, combined with delayed accretion disk formation, can provide a unified explanation for the diverse TDE observations, e.g., the optical/X-ray population and the frequently observed rebrightening bump. …”

Exploring Variation of Double-peak Broad-line Profile in Strongly Variable AGNs by Jiancheng Wu, Qingwen Wu, Kai-Xing Lu, Xinwu Cao, Xiangli Lei, Mengye Wang, Xiao Fan

“…In this work, we explore the evolution of line profiles in variable AGNs based on the BLR model of Czerny and Hryniewicz, where the BLR is driven by the radiation pressure acting on dust at the surface layers of the accretion disk. The line profiles in the low-Eddington-ratio regime show a double-peak profile, which will become a single peak at high Eddington ratios. …”

A New Interpretation for the Hot Corona in Active Galactic Nuclei by Yu Zhao, Yan-Rong Li, Jian-Min Wang

“…Within this reconnection layer, the tearing instability leads to the formation of a chain of plasmoids, which contain relativistic electrons that generate X-ray radiation through inverse-Compton (IC) scattering of soft photons emitted by the accretion disk. Based on previous theoretical works and numerical simulations, we develop a heuristic framework to parameterize the geometry and magnetization of the reconnection layer, as well as to compute both the power of the IC-scattering radiation and the height of the reconnection layer. …”

Kilonova/Macronova Emission from Compact Binary Mergers by Masaomi Tanaka

“…The spectral peak is located in red optical or near-infrared wavelengths. A subsequent accretion disk wind may provide an additional luminosity or an earlier/bluer emission if it is not absorbed by the precedent dynamical ejecta. …”

The Disk Wind Contribution to the Gamma-Ray Emission from the Nearby Seyfert Galaxy GRS 1734−292 by Nobuyuki Sakai, Tomoya Yamada, Yoshiyuki Inoue, Ellis R. Owen, Tomonari Michiyama, Ryota Tomaru, Yasushi Fukazawa

“…Using a lepto-hadronic emission model based on a shocked ambient medium and a shocked wind region created by an AGN accretion disk wind, we identify two viable scenarios that are consistent with the Fermi-LAT data and multiwavelength observations: a hadronic pp -dominated scenario and a leptonic external-Compton-dominated scenario. …”

The Extraordinary Long-lasting Infrared Echo of PS16dtm Reveals an Extremely Energetic Nuclear Outburst by Ning Jiang, Di Luo, Jiazheng Zhu, Roc M. Cutri

“…Such large energetic output compared to normal TDEs could be boosted by the preexisting accretion disk and gas clouds around the black hole. Our model can be validated in the near future by IR time-domain surveys such as the Near-Earth Object Surveyor, given the recent retirement of WISE. …”

Autoencoder Reconstruction of Cosmological Microlensing Magnification Maps by Somayeh Khakpash, Federica B. Bianco, Georgios Vernardos, Gregory Dobler, Charles Keeton

“…Even though we observe a mild loss of resolution in the generated maps, we find this effect to be smaller than the smoothing effect of convolving the original map with a source of a plausible size for its accretion disk in the red end of the optical spectrum and larger wavelengths and particularly one suitable for studying the broad-line region of quasars. …”

Physical Pathways for JWST-observed Supermassive Black Holes in the Early Universe by Junehyoung Jeon, Volker Bromm, Boyuan Liu, Steven L. Finkelstein

“…To grow the DCBHs, we implement a gas swallowing model set to match the Eddington accretion rate as long as the nearby gaseous environment, affected by stellar and accretion disk feedback, provides sufficient fuel. We find that to create massive AGN in overmassive systems at high redshifts, massive seeds accreting more efficiently than the fiducial Bondi–Hoyle model are needed. …”

Extreme Scale Height Variations and Nozzle Shocks in Warped Disks by Nicholas Kaaz, Yoram Lithwick, Matthew Liska, Alexander Tchekhovskoy

“…Accretion disks around both stellar-mass and supermassive black holes (BHs) are likely often warped. …”

An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN RE J1034+396 by Chloe S. Taylor, Daniel R. Wilkins, Steven W. Allen

“…The 0.3–9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by relativistically blurred reflection from a highly ionized accretion disk. The source is known to exhibit strong excess soft X-ray emission, which we show is well represented by thermal disk photons Comptonized by a warm plasma spanning the inner accretion flow. …”

A Dichotomy in the 1–24 GHz Parsec-scale Radio Spectra of Radio-quiet Quasars by Sina Chen, Ari Laor, Ehud Behar, Ranieri D. Baldi, Joseph D. Gelfand, Amy E. Kimball

“…The flat 8.4–23.6 GHz slope sources may be associated with a continuous ejection starting at the accretion disk corona. The steep 8.4–23.6 GHz slope sources may be produced by an interaction of an active-galactic-nucleus-driven wind with the BLR gas or a low-power jet extending to the BLR scale. …”
