Supermassive black holes lying in the center of galaxies can launch relativistic jets of
plasma along their polar axis. The physics of black-hole jets is a very active research topic in …

In this work the tensile behaviour of selective laser melted (SLMed) aluminium alloy A357 in
the as-fabricated and heat-treated states is explained using scanning electron microscopy …

The recent hint of correlated γ-ray and neutrino emission from the blazar TXS 0506+ 056
has renewed interest in blazars as the source of high-energy neutrinos, in which the …

The first statistically significant detection of the cosmic γ-ray horizon (CGRH) that is
independent of any extragalactic background light (EBL) model is presented. The CGRH is a …

In this work, a time-dependent modelling is developed to study the emission properties of
blazars in the low state. Motivated by various observations, we speculate and assume that …

The blazar TXS 0506+ 056 got into the spotlight of the astrophysical community in 2017
September, when a highenergy neutrino detected by IceCube (IceCube-170922A) was …

The study of blazar jet has been performed for several decades via VLBI technique, while its
generation and propagation stay unclear. In the present work, we compiled a sample of 407 …

We have analysed a large sample of clean blazars detected by Fermi Large Area Telescope
(LAT). Using the literature and calculation, we obtained intrinsic γ-ray luminosity excluding …

The extragalactic γ-rays sky observed by the Fermi Large Area Telescope (LAT) is
dominated by blazars. In the fourth release of the Fermi LAT Point Source Catalog (4FGL) …

In the study of radiation mechanisms of active galactic nuclei (AGN) jets, hadronuclear (pp)
interactions are commonly neglected, because the number density of cold protons in the jet …
