Stellar Evolution in AGN Disks

Matteo Cantiello et al.

Summary: AGN stars, embedded in extreme astrophysical environments, have different evolutionary conditions from normal stars, being strongly affected by mass accretion and loss, with chemical mixing playing a critical role in their evolution.

Orbital Evolution of Binary Black Holes in Active Galactic Nucleus Disks: A Disk Channel for Binary Black Hole Mergers?

Ya-Ping Li et al.

Summary: The study examines the merger of equal-mass binary black holes in AGN accretion disks, finding that the gravitational softening used for the binary has a significant impact. Prograde BBHs expand rather than harden with small softening, but harden with larger softening. Retrograde BBHs consistently harden regardless of softening, suggesting that gas-driven inspiral of retrograde binaries can lead to compact BBHs in the gravitational-wave-emitting regime.

Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Slowly Transient Appearance

Jian-Min Wang et al.

Summary: Compact objects known as accretion-modified stars are expected to be trapped within the dense environment of supermassive black hole disks in active galactic nuclei. The hyper-Eddington accretion rates onto black holes in this context lead to outflows impacting the Bondi sphere, inducing episodic accretion. The resulting synchrotron flare from relativistic electrons contributes significantly to the emission of radio-quiet quasars, with the flare decaying slowly over a few months.

Magneto-hydrodynamic simulations of young supernova remnants and their energy-conversion phase

O. Petruk et al.

Summary: This study investigates the transition from supernova to supernova remnants, focusing on the shift from the early expansion stage to the Sedov stage and the role of magnetic fields in this transition. The results show that the radial component of the magnetic field rapidly decreases downstream from the forward shock, preventing the reproduction of radially aligned polarization patterns observed in some young SNRs in 1D MHD simulations.

Do LIGO/Virgo Black Hole Mergers Produce AGN Flares? The Case of GW190521 and Prospects for Reaching a Confident Association

A. Palmese et al.

Summary: The report discusses the association of the GW BBH merger event GW190521 with an AGN flare, highlighting the need for follow-up observations to establish confident associations. Their Bayesian formalism allows for the estimation of AGN associations and the inference of cosmological parameters from a sample of BBH events. Confident associations are crucial to avoid bias in astrophysical and cosmological constraints.

Supernova explosions in active galactic nuclear discs

Evgeni Grishin et al.

Summary: Active galactic nuclei (AGNs) are important environments for stellar events such as mergers and explosions. Our analytical model studies shock evolution and breakout characteristics in AGN discs. Bright explosions occur in lower density regions and may be observable in future high-cadence transient searches.

Analytical Solution of Magnetically Dominated Astrophysical Jets and Winds: Jet Launching, Acceleration, and Collimation

Liang Chen et al.

Summary: An analytical solution of highly magnetized jet/wind flow is presented, including three stages of acceleration describing the evolution of the jet in different speed and motion modes. The research results are consistent with known theoretical results and numerical simulations, and can be used to constrain the spin of black holes in astrophysical jets.

Neutron Star Mergers in Active Galactic Nucleus Accretion Disks: Cocoon and Ejecta Shock Breakouts

Jin-Ping Zhu et al.

Summary: The study explores the scenario where neutron star mergers occur at migration traps in active galactic nucleus disks, resulting in choked jets that power X-ray shock breakout transients. Subsequent nonrelativistic ejecta breaking through the disk generate X-ray/UV flares.
