Recognizing Blazars Using Radio Morphology from the VLA Sky Survey
The Astrophysical JournalBlazars are radio-loud active galactic nuclei whose jets have a very small angle to our line of sight. Observationally, the radio emissions are mostly compact or compact-core with a one-sided jet.

The unified model of compact radio sources [PDF]
arXiv, 2002 We propose the unified model of compact radio sources, i.e. of pulsars, maser sources, and active galactic nuclei. The unification is based on the wavelength dependence of radio source size. It is shown that the compact sources are characterized by a maser amplification of thermal radio emission. The density, temperature, and magnetic field profiles of

Angewandte Chemie, Volume 137, Issue 9, February 24, 2025.We report a multifaceted assessment of novel cyanine‐carborane salts as potent photosensitizers for photodynamic therapy (PDT). These compounds exhibit efficient tumor targeting through uptake by organic anion‐transporting polypeptides (OATP). Upon near‐infrared (NIR) light irradiation, cyanine‐carborane salts generate reactive oxygen species (ROS ...

Investigating the Star Formation Characteristics of Radio Active Galactic Nuclei
The Astrophysical JournalThe coevolution of supermassive black holes and their host galaxies represents a fundamental question in astrophysics. One approach to investigating this question involves comparing the star formation rates (SFRs) of active galactic nuclei (AGNs) with ...

The radio spectra of galactic nuclei [PDF]
arXiv, 1997 We present a model for the inverted radio spectra of active active galactic nuclei as well as the central regions of normal galaxies. The model is based on the unified scenario for active galaxies, stating that the central engines of active galaxies consists of a supermassive black hole surrounded by an accretion disk and a radio jet.

Deciphering Radio Emissions from Accretion Disk Winds in Radio-quiet Active Galactic Nuclei
The Astrophysical JournalUnraveling the origins of radio emissions from radio-quiet active galactic nuclei (RQ AGNs) remains a pivotal challenge in astrophysics. One potential source of this radiation is the shock interaction between AGN disk winds and the interstellar medium ...

Galactic jet sources and the AGN connection [PDF]
arXiv, 1995 In order to further test our hypothesis that jets and disk around compact accreting objects are symbiotic features we investigate the newly discovered superluminal galactic radio jets GRS 1915+105 and GRO J1655-40 and the two famous galactic radio jets 1E1740-2942 and SS 433 within the framework of our couple jet/disk model developed initially for ...

The Astrophysical JournalBased on the magnetization, an accretion disk with a large-scale magnetic field can be separated into either standard and normal evolution or magnetically arrested disk (MAD), which are difficult to identify from observations. It is still unclear whether
