Dynamical Age vs Spectral Age of the Lobes of Selected Giant Radio Sources (GRSs)
J. Machalski, M. Jamrozy, D. J. Saikia
Dynamical ages of the opposite lobes determined {\sl independently} of each other suggest that their ratios are between 1.1 to 1.4. Demanding similar values of the jet…
A Multifrequency Study of Double-Double Radio Galaxies
M. Jamrozy, C. Konar, D. J. Saikia +1
One of the striking examples of episodic activity in active galactic nuclei are the double-double radio galaxies (DDRGs) with two pairs of oppositely-directed radio lobes from two…
Spectral Ages of Giant Radio Sources
C. Konar, D. J. Saikia, M. Jamrozy +1
Multifrequency observations with the GMRT and the VLA are used to determine the spectral breaks in consecutive strips along the lobes of a sample of selected giant radio sources (G…
Possible Relic Lobes in Giant Radio Sources
S. Godambe, C. Konar, D. J. Saikia +1
We present low-frequency observations with the GMRT of three giant radio sources (J0139+3957, J0200+4049 and J0807+7400) with relaxed diffuse lobes which show no hotspots and no ev…
Small-scale magnetic helicity losses from a mean-field dynamo
Axel Brandenburg, Simon Candelaresi, Piyali Chatterjee
Using mean-field models with a dynamical quenching formalism we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to allevia…
A multifrequency study of giant radio sources III. Dynamical age vs. spectral age of the lobes of selected sources
J. Machalski, M. Jamrozy, D. J. Saikia
The dynamical ages of the opposite lobes of selected giant radio sources are estimated using the DYNAGE algorithm of Machalski et al., and compared with their spectral ages estimat…
