Tracing the assembly histories of galaxy clusters in the nearby universe

César A. Caretta, Heinz Andernach, Marcel Chow-Martínez +10

We have compiled a sample of 67 nearby ( < 0.15) clusters of galaxies, for which on average more than 150 spectroscopic members are available, and, by applying different methods…

Deep Learning for Morphological Identification of Extended Radio Galaxies using Weak Labels

Nikhel Gupta, Zeeshan Hayder, Ray P. Norris +7

The present work discusses the use of a weakly-supervised deep learning algorithm that reduces the cost of labelling pixel-level masks for complex radio galaxies with multiple comp…

Hydra II: Characterisation of Aegean, Caesar, ProFound, PyBDSF, and Selavy source finders

M. M. Boyce, A. M. Hopkins, S. Riggi +24

We present a comparison between the performance of a selection of source finders using a new software tool called Hydra. The companion paper, Paper~I, introduced the Hydra tool and…

Hydra I: An extensible multi-source-finder comparison and cataloguing tool

M. M. Boyce, A. M. Hopkins, S. Riggi +24

The latest generation of radio surveys are now producing sky survey images containing many millions of radio sources. In this context it is highly desirable to understand the perfo…

MeerKAT discovery of a double radio relic and odd radio circle: connecting cluster and galaxy merger shocks

Bärbel S. Koribalski, Angie Veronica, Klaus Dolag +11

We present the serendipitous discovery of (1) a large double radio relic associated with the galaxy cluster PSZ2 G277.93+12.34 and (2) a new odd radio circle, ORC J1027-4422, both…

A Quick Look at the 3GHz Radio Sky. II. Hunting for DRAGNs in the VLA Sky Survey

Yjan A. Gordon, Lawrence Rudnick, Heinz Andernach +9

Active Galactic Nuclei (AGN) can often be identified in radio images as two lobes, sometimes connected to a core by a radio jet. This multi-component morphology unfortunately creat…
