Discovery of a 100 kpc Narrow Curved Twin Jet in the S-shaped Giant Radio Galaxy J0644+1043
The Astrophysical JournalWe report the discovery of an S-shaped morphology of the radio galaxy J0644+1043 imaged with a 30 μ Jy beam ^−1 sensitive 525 MHz broadband (bands 3 + 4) uGMRT map.

The Astrophysical JournalThe origin of diffuse high-energy neutrinos from TeV to PeV energies detected by the IceCube Observatory remains a mystery. In our previous work, we have shown that hadronuclear ( p − p ) interactions in active galactic nuclei (AGNs) jets could be ...

Probing the High-frequency Variability of NGC 5044: The Key to Active Galactic Nucleus Feedback
The Astrophysical JournalThe active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to study AGN feedback. It hosts the largest known reservoir of cold gas in any

Jetted subgalactic-size radio sources in merging galaxies
Astronomy & AstrophysicsContext. The long-standing question concerning jetted subgalactic-size (JSS) radio sources is whether they will evolve into large radio galaxies, die before escaping the host galaxy, or remain indefinitely confined to their compact size. Aims. Our main goal is to propose a scenario that explains the relative number of JSS radio sources and their ...

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars
The Astrophysical Journal LettersStudying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Astronomy & AstrophysicsContext. Early-type galaxies host low-luminosity active galactic nuclei, as indicated by radio emission spanning up to several orders of magnitude in terms of the physical scale, ranging from compact parsec-scale to extended kiloparsec-scale radio ...

Modeling Cosmological Evolution of Jetted Seyfert Galaxies for z ≲ 10
The Astrophysical JournalWe use high-resolution cosmological zoom-in simulations to model mechanical and thermal feedback from active galactic nuclei onto the evolution of Seyfert-type galaxies, studying the morphology of central galaxies growing within dark matter (DM) halos ...
