HI absorption in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 2002 Twenty-two powerful radio galaxies have been searched for HI absorption. We find the highest probability of detecting HI in absorption among narrow-line compact (or small) galaxies or galaxies with indication of richer interstellar medium (i.e. with ongoing or recent star-formation).

Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions
EPJ Web of Conferences, 2013 Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.

National Materials, EarlyView.Circular differential scattering (CDS) spectroscopy relies on a modified dark‐field optical microscope to study single chiral nanostructures, avoiding the averaging effects of ensemble methods. Recently achieving improved detection limits of 1.5%, this robust technique analyzes plasmonic chirality and molecular interactions, with the future goal of ...

Small, EarlyView.This study reports intrinsically stretchable neuromorphic devices that exhibit outstanding mechanical stability while fully preserving their electrical characteristics over 105 repeated deformation cycles under 50% tensile strain. Such robustness is achieved through a rational molecular design strategy that systematically modulates the chain packing of

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 ...

A Context‐Aware Decision Support Framework for Scientific Experiment Configuration
Software: Practice and Experience, EarlyView.ABSTRACT Introduction Defining an experimental configuration is a complex decision problem for early‐stage researchers, who must map goals, constraints, and requirements onto datasets, algorithms, and parameter settings that directly affect experimental outcomes.

Radio Galaxies at TeV Energies: Preface
Galaxies, 2020 The majority of the known extragalactic sky from TeV gamma-ray energies consists of blazars having plasma jets pointing in the direction of the line-of-sight, which results in a large Doppler boosting of their emission.

Radio Galaxy Classification: #Tags, Not Boxes
Galaxies, 2021 After six decades of studying radio galaxies, we are now delightfully overwhelmed by their exponentially expanding numbers and the complexity of their structures.
