A Census of Active Galactic Nuclei Identified by the Mid-infrared [Ne v] Line at z ≤ 0.025
The Astrophysical JournalWe present a census of local active galactic nuclei (AGN) at a redshift of z ≤ 0.025 selected using the high-ionization [Ne v ] λ 14.32 μ m emission line from the Infrared Database of Extragalactic Observables from Spitzer.

New Conformally Invariant Born–Infeld Models and Geometrical Currents
PhysicsA new conformally invariant gravitational generalization of the Born–Infeld (BI) model is proposed and analyzed from the point of view of symmetries. Taking a geometric identity involving the determinant functions detfBμν, Fμν with the Bach Bμν and the ...

The different neighbours around Type-1 and Type-2 active galactic nuclei
, 2014 One of the most intriguing open issues in galaxy evolution is the structure and evolution of active galactic nuclei (AGN) that emit intense light believed to come from an accretion disk near a super-massive black hole (Rees 1984, Lynden-Bell 1969).

Simulations of Galactic Outflows Driven by Active Galactic Nuclei and Starbursts
The Astrophysical JournalUsing the hydro code Athena++ , we run a series of large-scale hydrodynamic simulations of galactic outflows on a scale of ∼5 kpc scale over a time period of 5 Myr.

ParticlesThe para-positronium system S01Ps is described by means of specially constructed coherent states (CSs) in the Klauder–Perelomov sense. It is analyzed from the physical point of view and from the geometry underlying the relevant symmetry group ...

Atoms, 2019 The mechanism of the optical variability of active galactic nuclei (AGN) is still very puzzling. It is now widely accepted that the optical variability of AGN is stochastic, producing red noise-like light curves. In case they were to be periodic or quasi-

The sign of active galactic nucleus quenching in a merger remnant with radio jets
, 2015 We investigate optical, infrared, and radio active galactic nucleus (AGN) signs in the merger remnant Arp 187, which hosts luminous jets launched in the order of $10^5$ yr ago but whose present-day AGN activity is still unknown.

The Merging Galaxy Cluster Environment Affects the Morphology of Radio Active Galactic Nuclei
The Astrophysical JournalIt has previously been found that the galaxy cluster environment can affect the fueling and evolution of active galactic nuclei (AGN). This work examines the effect of the merging cluster environment on the properties of radio AGN by comparing the radio ...
