Relativistic Jets in Gamma-Ray-Emitting Narrow-Line Seyfert 1 Galaxies

open access: yesGalaxies, 2019
Before the launch of the Fermi Gamma-ray Space Telescope satellite only two classes of active galactic nuclei (AGN) were known to generate relativistic jets and thus to emit up to the γ -ray energy range: blazars and radio galaxies, both hosted

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

A multi-wavelength study of powerful high redshift radio galaxies [PDF]

open access: yes, 2021
Philosophiae Doctor - PhDWe present a new sample of distant powerful radio galaxies, in order to study their host-galaxy properties and provide targets for future observations of Hi absorption with new radio telescopes.

Minor epic: Notes toward a different “Anthropoetry”

open access: yesAnthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival

The Nuclear Structure of the Giant Radio Galaxy 3C236 [PDF]

open access: yesSymposium - International Astronomical Union, 2002
We present the nuclear structure of the radio galaxy 3C236 obtained by VLBI and MERLIN observations at both 1.663 and 5 GHz. Comparison with an HST WFPC-2 image of 3C236 suggests that the radio axis is at an angle of ∼ 30° to the plane of the sky, and 3C236 has an overall size of 4.5 Mpc and contains the longest jet known in the universe.

A Morphological Identification and Study of Radio Galaxies from LoTSS DR2. I. The “Winged” Radio Galaxies

open access: yesThe Astrophysical Journal Supplement Series
We conducted an extensive identification and analysis of various morphological classes and subclasses of radio galaxies using the latest high-resolution data from the second data release of the LOFAR Two-metre Sky Survey.

A Possible Solution to the Mystery of the ANITA Anomalous Events

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

SwarmGenomics: A Unified Pipeline for Individual‐Based Whole‐Genome Analyses

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Advances in sequencing technologies have made whole‐genome data widely accessible, enabling research in population genetics, evolutionary biology, and conservation. However, analysing whole‐genome sequencing (WGS) data remains challenging, often requiring multiple specialised tools and substantial bioinformatics expertise.
