Discovery of sulfur oxides in the ejecta of a B[e] supergiant
C. Bordiu, J. Ricardo Rizzo, D. Navarro-Almaida +12
B[e] supergiants represent a rare class of luminous, evolved massive stars surrounded by dusty circumstellar disks. Since their intense UV fields were long thought to sterilize the…
MeerKAT discovery of 164 compact radio rings toward the Galactic Plane
C. Bordiu, F. Bufano, G. Umana +14
We report the discovery of 164 compact (radius < 1 arcmin) radio rings using MeerKAT 1.3 GHz data from the SARAO MeerKAT Galactic Plane Survey (l=2-60deg, 252-358deg, |b|<1.5deg) a…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky
A. M. Hopkins, A. Kapinska, J. Marvil +70
We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
ASKAP and VLASS search for a radio-continuum counterpart of ultra-high-energy neutrino event KM3-230213A
M. D. FilipoviÄ, Z. J. Smeaton, A. C. Bradley +23
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…
Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35
Miroslav D. FilipoviÄ, S. LazareviÄ, M. Araya +41
We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
