Diffuse Radio Emission from Galaxy Clusters
Sign Up to like & getrecommendations! Published in 2019 at "Space Science Reviews"
DOI: 10.1007/s11214-019-0584-z
Abstract: In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies. The radio emission reveal the presence of cosmic rays and magnetic… read more here.

DOI: 10.1017/pasa.2018.26
Abstract: Abstract We present new observations of the large-scale radio emission surrounding the lenticular galaxy NGC 1534 with the Australia Telescope Compact Array and Murchison Widefield Array. We find no significant compact emission from the nucleus… read more here.

DOI: 10.1038/s41550-019-0765-4
Abstract: The central nuclei of galaxies, where supermassive black holes (SMBHs) are thought to reside, can experience phases of activity when they become active galactic nuclei (AGNs). An AGN can eject winds and jets and produce… read more here.

DOI: 10.1051/0004-6361/201730948
Abstract: Context. The binary system AR Sco contains an M star and the only known radio-pulsing white dwarf. The system shows emission from radio to X-rays, likely dominated by synchrotron radiation. The mechanism that produces most… read more here.

DOI: 10.1088/1674-4527/acd16b
Abstract: This paper presents an automatic multi-band source cross-identification method based on deep learning to identify the hosts of extragalactic radio emission structures. The aim is to satisfy the increased demand for automatic radio source identification… read more here.

A rotation-driven pulsar radio emission mechanism

DOI: 10.1093/mnras/staa3529
Abstract: We propose and discuss an alternative pulsar radio emission mechanism that relies on rotation-driven plasma oscillations, rather than on a beam-driven instability, and suggest that it may be the generic radio emission mechanism for pulsars.… read more here.

DOI: 10.1093/mnras/stab1965
Abstract: Low-mass (M500 < 5 × 1014 M⊙) galaxy clusters have been largely unexplored in radio observations, because of the inadequate sensitivity of existing telescopes. However, the upgraded Giant Metrewave Radio Telescope (uGMRT) and the Low Frequency ARray… read more here.
