Ultra-Steep Spectrum Radio `Jellyfish' Uncovered in Abell 2877
Torrance Hodgson, Iacopo Bartalucci, Melanie Johnston-Hollitt +3
We report on the discovery of a mysterious ultra-steep spectrum (USS) synchrotron source in the galaxy cluster Abell 2877. We have observed the source with the Murchison Widefield…
SPT-CL J2032-5627: a new Southern double relic cluster observed with ASKAP
S. W. Duchesne, M. Johnston-Hollitt, I. Bartalucci +2
We present a radio and X-ray analysis of the galaxy cluster SPT-CL J2032-5627. Investigation of public data from the Australian Square Kilometre Array Pathfinder (ASKAP) at 943 MHz…
Low(er) frequency follow-up of 28 candidate, large-scale synchrotron sources
Torrance Hodgson, Melanie Johnston-Hollitt, Benajmin McKinley +2
We follow up on a report by Vacca et al. (2018) of 28 candidate large-scale diffuse synchrotron sources in an 8°8° area of the sky (centred at RA 5h0m0s Dec 5°48'0''). Thes…
ASKAP reveals giant radio halos in two merging SPT galaxy clusters -- Making the case for a direction-dependent pipeline --
Amanda G. Wilber, Melanie Johnston-Hollitt, Stefan W. Duchesne +4
Early science observations from the Australian Square Kilometre Array Pathfinder (ASKAP) have revealed clear signals of diffuse radio emission associated with two clusters detected…
