Multipole Functions for Image Analysis II: Equal Area Weighting and Application to Supernova Remnant Images
D. A. Leahy, S. Ranasinghe, M. D. Filipovic +1
New basis functions for 2 dimensional (2D) image analysis with a circular boundary (referred to as multipole analysis) are derived which are equal-area weighted. We present open ac…
The Salamander: A case study of the magnetic field and peculiar morphology of G309.8-2.6 through radio polarimetry
Wenhui Jing, Jennifer L. West, Xiaohui Sun +17
Studying the interaction between core-collapse supernova remnants (SNRs) and their surrounding environments is essential to understanding the mechanism for energy transfer to the i…
WALLABY pilot survey: Blinded by the light -- discovery of a fourth member in the ESO 179-013 system
Rayssa Guimarães Silva, Marco Grossi, Denise R. Gonçalves +12
We present new ASKAP/WALLABY HI observations of the nearby dwarf galaxy system ESO 179-013 (Kathryn's Wheel), the nearest known collisional ring galaxy, located 10 Mpc away in the…
Multi-frequency radio-continuum study of the LMC SNR N206 (Goat's Eye) and its "zig-zag" PWN
M. Ghavam, Z. J. Smeaton, M. D. Filipovic +17
We present new radio-continuum observations of the Large Magellanic Cloud (LMC) supernova remnant (SNR) N206, which we give the name "Goat's Eye". Goat's Eye contains an interior r…
Evolutionary Map of the Universe: A pilot survey to detect high Galactic latitude pulsars in variance images with ASKAP
A. Ahmad, S. Dai, E. Lenc +13
It has been proposed that radio pulsars can be distinguished from other point-like radio sources in continuum images by their unique interstellar scintillation signatures. Using da…
New ASKAP radio-continuum surveys of the Small Magellanic Cloud
O. K. Khattab, M. D. Filipovic', Z. J. Smeaton +5
We present two new radio continuum images from the ASKAP POSSUM survey in the direction of the Small Magellanic Cloud. The two new source lists contain 36,571 radio continuum sourc…
