The Milliarcsecond Structure of Radio Galaxies and Quasars [PDF]
, 1982 Hybrid maps of the nuclei of radio galaxies and quasars show a variety of morphologies. Among compact sources, two structures are common: an asymmetric, “core-jet” morphology (eg, 3C 273), and an “equal double” morphology with two separated, similar ...

Relativistic Beaming and the Nuclei of Double-lobed Radio Quasars [PDF]
Symposium - International Astronomical Union, 1988 We have defined a complete sample of double-lobed 3CR quasars with minimal orientation bias. Properties of these objects on the >kpc scale are consistent with the simple beaming model for their nuclei. VLBI maps of six nuclei reveal “core-jet” structures.

Cosmology from double quasars [PDF]
, 2023 Los sistemas lente gravitacional han demostrado ser altamente valiosos en el estudio de la distribución de masa de las galaxias que actúan como deflectores, y tienen un gran potencial como herramienta para medir la constante de Hubble (H0).

Ionized Gas Outflows from the MAGNUM Survey: NGC 1365 and NGC 4945
Frontiers in Astronomy and Space Sciences, 2017 AGN feedback, acting through strong outflows accelerated in the nuclear region of AGN hosts, is invoked as a key ingredient for galaxy evolution by many models to explain the observed BH-galaxy scaling relations.

Dynamic Regulation of Endogenous Transcription Factor Hubs at Single‐Molecule Resolution
Advanced Science, EarlyView.This study combines single‐molecule microscopy and genome editing to characterize the dynamic behaviors of endogenous oncofusion transcription factor EWS::FLI1 in Ewing sarcoma cells. EWS::FLI1 forms neomorphic hubs that dynamically assemble and dissolve. The hubs are regulated during mitosis, by RNA, and by specific chemicals.

Progress in Photovoltaics: Research and Applications, EarlyView.This study examines the reuse readiness of photovoltaic modules through the Swiss PV Circle project. Results confirm technical feasibility with cost savings from targeted preselection, whereas economic viability depends on module age, testing, and market conditions.

An Evolutionary Model for Quasars [PDF]
, 1976 A simple, though not necessarily unique, model for the cosmic population dynamics of quasars is presented. This model incorporates a double evolutionary trend: (i) a strong luminosity evolution, the presence of which we have discussed previously (Zotov ...

2 NEW CANDIDATE SUPERLUMINAL QUASARS - 4C 28.45 AND 4C 21.35 [PDF]
, 1992 Multi-epoch VLBI observations are presented of two large double-lobed quasars, 4C 28.45 (1830 + 285) and 4C 21.35 (1222 + 216). On mas-scales, both quasars contain a multi-component asymmetric radio structure. In 4C 28.45 the nuclear emission was seen to
