Observational Evidence for a Correlation between the Magnetic Field of Jets and Star Formation Rate in Host Galaxies

The Astrophysical Journal
Accretion supermassive black holes in the center of active galaxies usually produce “jet”-collimated bipolar outflows of relativistic particles. Magnetic fields near the black hole event horizon may play a crucial role in the formation of jets/outflows ...

Detection of Periodic Radio Signal from the Blazar J1043+2408

Galaxies, 2018
The search for periodic signals from blazars has become a widely discussed topic in recent years. In the scenario that such periodic changes originate from the innermost regions of blazars, the signals bear imprints of the processes occurring near the ...

The Use of Binary Black Holes Merging in Active Galactic Nuclei Disks for Hubble Constant Measurements

The Astrophysical Journal
We study the impact of environmental effects on the measurement of the Hubble constant ( H _0 ) from gravitational-wave (GW) observations of binary black hole mergers residing in active galactic nuclei (AGNs) near the central supermassive black hole ...
