SZ effect from radio-galaxy lobes: astrophysical and cosmological relevance [PDF]
, 2008 We derive the SZ effect arising in radio-galaxy lobes that are filled with high-energy, non-thermal electrons. We provide here quantitative estimates for SZ effect expected from the radio galaxy lobes by normalizing it to the Inverse-Compton light ...

Symmetry in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1982 One of the most striking properties of the radio galaxies is the predominance of a symmetrical double lobed structure. Any model to explain the energy release and collimation in radio galaxies must be able to produce this symmetry as the normal morphology.

Gas Outflows in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 2004 We present a summary of our recent results on gas outflows in radio galaxies. Fast outflows (up to 2000 km s−1) have been detected both in ionized and neutral gas. The latter is particularly surprising as it shows that, despite the extremely energetic phenomena occurring near an AGN, some of the outflowing gas remains, or becomes again, neutral.

Probing the evolution of galaxy clusters using SZ effect and non-thermal emission: First results from A1413 [PDF]
EPJ Web of ConferencesMass is the most fundamental property of galaxy clusters. However, measuring it is still a challenge. Calibrating mass from intracluster medium observables such as the Sunyaev-Zel’dovich (SZ) effect is subject to uncertainty and biases because of the ...

Subarcsecond-resolution Imaging of M51 with the International LOFAR Telescope
The Astrophysical Journal, 2023 We present an International LOFAR Telescope (ILT) subarcsecond-resolution image of the nearby galaxy M51 with a beam size of 0.″436 × 0.″366 and rms of 46 μ Jy. We compare this image with a European VLBI Network study of M51 and discuss the supernovae in

Radio Galaxies—The TeV Challenge [PDF]
Galaxies, 2018 Over the past decade, our knowledge of the γ -ray sky has been revolutionized by ground- and space-based observatories by detecting photons up to several hundreds of tera-electron volt (TeV) energies. A major population of the γ -ray bright objects are active galactic nuclei (AGN) with their relativistic jets pointed along our line-of-sight ...

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.
