EMU radio observations of barred spiral galaxy NGC 5938 (Araish)

Hina Zakir, M.D. Filipovic, Luke A. Barnes, R. Z. E. Alsaberi et autres

Abstract We present multi-wavelength observations of the nearby spiral galaxy NGC 5938 (Araish) to investigate the origin of its radio emission, specifically the contribution from active galactic nucleus (AGN) activity and star formation. Using Evolutionary Map of the Universe (EMU) data, we …

ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412–751016 (Anglerfish)

Miroslav D Filipović, Zachary J. Smeaton, Andy Bradley, R. Kothes et autres

Abstract We report diffuse extended radio-continuum emission spatially coinciding with the IR source, WISEA J094409.17 $-$ 751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio data from the large-scale Evolutionary Map of the Universe (EMU) survey to analyse this …

Cosmological fine-tuning: the view from 2025

Geraint F. Lewis, Luke A. Barnes, Philip K. Goff

Abstract In recent decades, it has become clear that if our universe had been born with slightly different physics, e.g. if the masses of fundamental particles were altered by a tiny fraction, it would be sterile and uninhabitable. We explore the current …

ASKAP and VLASS Search for a Radio-continuum Counterpart of Ultra-high-energy Neutrino Event KM3–230213A

Miroslav D Filipović, Zachary J. Smeaton, Andy Bradley, Dougal Dobie et autres

Abstract We present the results of an Australian Square Kilometre Array Pathfinder (ASKAP) 944 MHz and Very Large Array Sky Survey (VLASS) 3 GHz search for a radio-continuum counterpart of the recent ultra-high-energy neutrino event, KM3–230213A. Using ASKAP, we catalog 1052 radio …

ASKAP–EMU radio continuum detection of planetary nebula NGC 5189: the ‘Infinity’ nebula

Albany Asher, Zachary J. Smeaton, Miroslav D Filipović, Andrew Hopkins et autres

Abstract We report the radio continuum detection of well-known Galactic Planetary Nebula (PN) NGC 5189, observed at 943 MHz during the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) survey. Two detections of NGC 5189 have been made …

Impact Cratering on the Saturnian Moon Tethys: A Complete Population Map and Geologic Analysis.

Emma Stanton, Imogen Jones, Luke A. Barnes

Impact cratering is a valuable field of research through which the geological history, surface evolution, and formation of Saturnian moons can be understood. To increase our understanding of the formation and current composition of the Saturnian system, moons such as Tethys must …
