A Search for Technosignatures toward the Galactic Centre at 150 MHz
Chenoa D. Tremblay, Danny C. Price, Steven J. Tingay
This paper is the fourth in a series of low-frequency searches for technosignatures. Using the Murchison Widefield Array over two nights we integrate 7 hours of data toward the Gal…
Early Science from POSSUM: Shocks, turbulence, and a massive new reservoir of ionised gas in the Fornax cluster
C. S. Anderson, G. H. Heald, J. A. Eilek +19
We present the first Faraday rotation measure (RM) grid study of an individual low-mass cluster -- the Fornax cluster -- which is presently undergoing a series of mergers. Exploiti…
First Search for Low-Frequency CH with a Square Kilometre Array Precursor Telescope
Chenoa D. Tremblay, James A. Green, Stacy L. Mader +2
The diatomic free radical methylidyne (CH) is an important tracer of the interstellar medium and the study of it was critical to our earliest understanding of star formation. Altho…
Low-Frequency Carbon Recombination Lines in the Orion Molecular Cloud Complex
Chenoa D. Tremblay, Christopher H. Jordan, Maria Cunningham +2
We detail tentative detections of low-frequency carbon radio recombination lines from within the Orion molecular cloud complex observed at 99-129 MHz. These tentative detections in…
A First Look for Molecules between 103 and 133 MHz using the Murchison Widefield Array
Chenoa Tremblay, Natasha Hurley-Walker, Maria Cunningham +4
We detail and present results from a pilot study to assess the feasibility of detecting molecular lines at low radio frequencies. We observed a 400 square degree region centred on…
Compact Symmetric Objects and Supermassive Binary Black Holes in the VLBA Imaging and Polarimetry Survey
S. E. Tremblay, G. B. Taylor, A. A. Ortiz +3
We present multi-frequency Very Long Baseline Array (VLBA) follow-up observations of VLBA Imaging and Polarimetry Survey sources identified as likely compact symmetric objects (CSO…
