Non-thermal emission in jets and winds: Expected emission and spectral index distributions
M. Meenakshi, D. Mukherjee, G. Bodo +5
The origin of synchrotron emission in compact radio sources associated with active galactic nuclei (AGN) remains poorly understood. In a series of papers, we have examined diagnost…
Dual AGN and Multiple SMBH Systems in the Era of SKAO
Q. D'Amato, L. Cui, R. Deane +23
We present a radio-oriented review of current strategies for the detection and characterization of dual active galactic nuclei (DAGN) and supermassive black hole binaries (SMBHBs),…
A Rare Gamma-ray Flaring episode of the Narrow-Line Seyfert 1 Galaxy 1H 0323+342
Aminabi Thekkoth, Vaidehi S. Paliya, Preeti Kharb
Gamma-ray-emitting narrow-line Seyfert 1 (-NLSy1) galaxies represent an enigmatic class of active galactic nuclei (AGNs) bridging populations of radio-quiet and radio-loud AGNs…
Survey of compact sources for pulsars and exotic objects -- I. Overview and initial discoveries
Yogesh Maan, Apurba Bera, Dharam Vir Lal +4
Targeted searches for pulsars based on their counterparts in radio images have resulted in the discovery of interesting pulsars including the first ever discovered millisecond puls…
VLTI-GRAVITY observations of blazars
Talvikki Hovatta, Elina Lindfors, Heidi Korhonen +5
Parsec-scale jets of blazars have so far been spatially resolved only in millimeter and submillimeter wavelengths, where very long baseline interferometry can be used to obtain mil…
AGN Fueling and Radio Jet Evolution in the Galaxy Group NGC 5044 revealed by VLBA HI Absorption and Proper-Motion Radio Observations
Francesco Ubertosi, Ewan O'Sullivan, Gerrit Schellenberger +8
The role of cooling gas in triggering active galactic nucleus (AGN) feedback in the centers of galaxy groups and clusters remains a key open question. NGC 5044, the X-ray brightest…
