The Fate of EMRI-IMRI Pairs in Active Galactic Nucleus Accretion Disks: Hydrodynamical and Three-body Simulations

The Astrophysical Journal
Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs) are important gravitational wave (GW) sources for the Laser Interferometer Space Antenna.

Low-mass black holes as the remnants of primordial black hole formation [PDF]

, 2012
Bridging the gap between the approximately ten solar mass ’stellar mass’ black holes and the ’supermassive’ black holes of millions to billions of solar masses are the elusive ’intermediate-mass’ black holes.

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

A New Timescale–Mass Scaling for the Optical Variation of Active Galactic Nuclei across the Intermediate-mass to Supermassive Scales

The Astrophysical Journal
The variability of active galactic nuclei (AGNs) has long been servicing as an essential avenue of exploring the accretion physics of a black hole (BH). There are two commonly used methods for analyzing AGN variability.

Simulation-based Prediction of Black Hole Spectra: From 10M⊙ to 108M⊙

The Astrophysical Journal
It has long been thought that black hole accretion flows are driven by magnetohydrodynamic turbulence, and there are now many general relativistic global simulations illustrating the dynamics of this process.

Lipid Nanoparticle Co‐Delivery of mRNA and a Small Molecule Drug for Oral Cancer Chemoimmunotherapy

Advanced Materials, EarlyView.
Co‐encapsulation of p53 mRNA and the small molecule ciclopirox within a lipid nanoparticle yields an all‐in‐one chemoimmunotherapy for oral squamous cell carcinoma. The platform engages caspase‐driven apoptosis in cancer cells while repolarizing tumor‐associated macrophages, achieving tumor reduction in both p53‐susceptible and p53‐resistant models and

HOLESOM: Constraining the Properties of Slowly Accreting Massive Black Holes with Self-organizing Maps

The Astrophysical Journal
Accreting massive black holes (MBHs, with M _• > 10 ^3 M _⊙ ) are known for their panchromatic emission, spanning from radio to gamma rays. While MBHs accreting at significant fractions of their Eddington rate are readily detectable, those accreting at ...
