GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) III: Galactic Plane
S. Mantovanini, N. Hurley-Walker, K. Ross +3
We present the third data release for the Galactic and Extragalactic All-Sky Murchison Widefield Array eXtended (GLEAM-X) survey, covering = 3800 deg2 of the southern Galactic Plan…
Low radio frequency detections of known pulsars and identification of new candidates with GLEAM-X: GP
Silvia Mantovanini, N. Hurley-Walker, G. Anderson +3
Image-based searches have become a complementary approach for identifying pulsars, particularly at MHz frequencies where scattering and high dispersion measures affect high-time re…
Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant
Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35
We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…
A Search for Low-frequency Radio Pulses from Long Gamma-ray Bursts with the Murchison Widefield Array
Fan Xu, G. E. Anderson, Jun Tian +10
It has been proposed that coherent radio emission could be emitted during or shortly following a gamma-ray burst (GRB). Here we present a low-frequency ( MHz) search for r…
Detecting the Black Hole Candidate Population in M51's Young Massive Star Clusters: Constraints on Accreting Intermediate Mass Black Holes
Kristen C. Dage, Evangelia Tremou, Bolivia Cuevas Otahola +24
Intermediate mass black holes (10^2 < M_BH< 10^5 Msun) are an open question in our understanding of black hole evolution and growth. They have long been linked to dense star cluste…
