A Wideband Polarization Observation of Hydra A with the Jansky Very Large Array
Lerato Baidoo, Richard A. Perley, Jean Eilek +3
We present results of a wideband high-resolution polarization study of Hydra A, one of the most luminous FR I radio galaxies known and amongst the most well-studied. The radio emis…
Bayesian radio interferometric imaging with direction-dependent calibration
Jakob Roth, Philipp Arras, Martin Reinecke +3
Context: Radio interferometers measure frequency components of the sky brightness, modulated by the gains of the individual radio antennas. Due to atmospheric turbulence and variat…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
A 4~Kpc Molecular Gas Lane in Cygnus A
C. L. Carilli, R. A. Perley, D. A. Perley +4
We present the discovery of a 4 kpc molecular gas lane in the Cygnus A host galaxy, using ALMA CO 2-1 observations. The gas lane is oriented roughly perpendicular to the projected…
Puzzling large-scale polarization in the galaxy cluster Abell 523
Valentina Vacca, Federica Govoni, Matteo Murgia +13
Large-scale magnetic fields reveal themselves through diffuse synchrotron sources observed in galaxy clusters such as radio halos. Total intensity filaments of these sources have b…
Spectral study of the diffuse synchrotron source in the galaxy cluster Abell 523
Valentina Vacca, Timothy Shimwell, Richard A. Perley +26
The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it one of the most signif…
