DOI: 10.1016/j.jastp.2017.05.016
Abstract: Abstract We present the results of observing the Cygnus-A radio source scintillation in the Earth's ionosphere under quiet and disturbed geomagnetic conditions by using the Irkutsk incoherent scattering radar (IISR). The scintillation method applied for… read more here.

DOI: 10.1093/mnras/staa1172
Abstract: Feedback from radio jets associated with Active Galactic Nuclei (AGN) plays a profound role in the evolution of galaxies. Kinetic power of these radio jets appears to show temporal variation, but the mechanism(s) responsible for… read more here.

DOI: 10.1093/mnras/sty3070
Abstract: We investigate the role of environment on radio galaxy properties by constructing a sample of large (≳100 kpc), nearby (???? < 0.3) radio sources identified as part of the Radio Galaxy Zoo citizen science project.… read more here.

DOI: 10.1126/science.abg6037
Abstract: Description Radio evidence of a stellar merger Core collapse supernovae occur when a massive star exhausts its fuel and explodes. Theorists have predicted that a similar explosion could occur if an evolved massive star merges… read more here.
