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.

Utopia Remembers: The Soviet Past in the Imagined Communist Future

The Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

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

The 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.

Neural Surrogate HMC: On Using Neural Likelihoods for Hamiltonian Monte Carlo in Simulation‐Based Inference

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Bayesian inference methods such as Markov Chain Monte Carlo (MCMC) typically require repeated computations of the likelihood function, but in some scenarios, this is infeasible and alternative methods are needed. Simulation‐based inference methods address this problem by using machine learning to amortize computations.

Blast: the far-infrared/radio correlation in distant galaxies [PDF]

, 2010
We investigate the correlation between far-infrared (FIR) and radio luminosities in distant galaxies, a lynchpin of modern astronomy. We use data from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST), Spitzer, the Large Apex BOlometer ...

Radio jets and gamma-ray emission in radio-silent narrow-line Seyfert 1 galaxies

, 2018
We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet.

Predicting CO and dust emission of star-forming galaxies

Astronomy & Astrophysics
In this work, we investigate whether dwarf galaxies differ from spirals and whether star formation produces radio and far-infrared (FIR) emission in the same way as it does for spiral galaxies.

Bridging Theory and Practice: Digital Twin Simulation of a Heat Exchanger in Laboratories for Engineering Students

Computer Applications in Engineering Education, Volume 34, Issue 5, September 2026.
ABSTRACT Digital twins serve as virtual replicas of physical systems. They can be used as a tool for engineering education by revealing the underlying principles behind unit operations. The project aimed to integrate digital twins into university engineering lab courses, complementing traditional methods by bridging the gap between experimentation and ...
