A twisted disk equation that describes warped galaxy disks
, 1994 Warped H1 gas layers in the outer regions of spiral galaxies usually display a noticeably twisted structure. This structure is thought to arise primarily as a result of differential precession in the H1 disk as it settles toward a 'preferred orientation'

Anisotropy of Core-collapse Supernovae Effected by the Disks of Active Galactic Nuclei
The Astrophysical JournalActive galactic nuclei (AGN) disks provide dense environments that influence star formation, evolution, and migration. In AGN disks, pressure gradients and migration accelerations could create the anisotropy of the core-collapse supernovae that occurs ...

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]
, 2013 The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...

Stellar CoRGI in MaNGA: Stellar Counterrotating Galaxies Identified in the MaNGA Survey
The Astrophysical Journal Supplement SeriesStellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions—a main, preexisting galaxy body with an older stellar population and a younger CR stellar disk likely formed from externally ...

Circumbinary Disk Spectra Irradiated by Two Central Accretion Disks in a Binary Black Hole System
The Astrophysical JournalWe study the effect of irradiation from two accretion disks (minidisks) around respective black holes of stellar-to-intermediate masses in a circular binary on the spectrum of a circumbinary disk (CBD) surrounding them. We assume the CBD to be a standard

Variable X-Ray Sources Associated with Extragalactic Supernova Remnants
The Astrophysical JournalWe report a serendipitous and unexpected discovery from a study of long-term X-ray variability in the nearby galaxy M83: a substantial fraction of X-ray sources classified as supernova remnants (SNRs) exhibit significant variability.

The Astrophysical JournalMassive stars may form in or be captured into active galactic nuclei (AGN) disks. Recent 1D studies employing stellar-evolution codes have demonstrated the potential for rapid growth of such stars through accretion up to a few hundred solar masses.
