The Astrophysical Journal, 2023 The dichotomy between radio-loud (RL) and radio-quiet (RQ) active galactic nuclei (AGNs) is thought to be intrinsically related to radio jet production. This difference may be explained by the presence of a strong magnetic field ( B -field) that enhances,

The Structure of Magnetic Fields in Spiral Galaxies: A Radio and Far-infrared Polarimetric Analysis
The Astrophysical Journal, 2023 We propose and apply a method to quantify the morphology of the large-scale ordered magnetic fields ( B -fields) in galaxies. This method is adapted from the analysis of Event Horizon Telescope polarization data.

Advanced Science, EarlyView.Ultraviolet (UV) imagers are important for a variety of applications but often require dedicated semiconductor process flows. Here, a versatile capacitive CMOS platform is transformed into a visible‐blind, multispectral UV imager through post‐CMOS functionalization with solution‐processed metal‐oxide nanoparticles. The UV‐induced photodielectric effect

A Simple Model of the Radio–Infrared Correlation Depending on Gas Surface Density and Redshift
The Astrophysical JournalWe introduce a simple parametric model of the radio–infrared correlation (i.e., the ratio between the IR luminosity and the 1.4 GHz radio luminosity, q _IR ) by considering the energy loss rate of high-energy cosmic-ray (CR) electrons governed by ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an
