Opportunity Lost in Searching for Technosignatures
Steve Prabu, David DeBoer, Andrew Siemion +6
The sensitivity of radio technosignature searches has improved dramatically over the last five decades; however, as the RFI environment from which these searches are conducted has…
The Lunar Farside Transients and Technology Telescope (LFT3) Mission
David R. DeBoer, Charlie K. Ashe, Owen A. Johnson +12
We present here an overview of the Lunar Farside Transients and Technology Telescope (LFT3) mission to take advantage of the extremely clear radio frequency environment on the luna…
Modelling Radio Frequency Interference on the Lunar Farside
Charlie K. Ashe, Ella J. Marshall, Evan F. Keane +3
Technological progress is a double-edged sword in the world of radio astronomy: improvements in antennas, receivers, and digital backends increase sensitivity, but rapid growth in…
A cooler look at the environment of Cygnus X-1: Searching for dynamical interactions within cold molecular gas
Pau Bosch-Cabot, Alexandra J. Tetarenko, Valentí Bosch-Ramon +7
We present IRAM--30m observations aimed at identifying potential outflow-interstellar medium interaction sites in the vicinity of the black hole X-ray binary Cygnus X--1, which dis…
Searching for Extraterrestrial Intelligence with the SKA
Chenoa D. Tremblay, Alex Andersson, Joe Bright +19
The search for technosignatures (also known as the Search for Extraterrestrial Intelligence or SETI) depends critically on our ability to distinguish artificial signals from the ri…
A jet bent by a stellar wind in the black hole X-ray binary Cygnus X-1
Steve Prabu, James C. A. Miller-Jones, Arash Bahramian +7
Jets provide an important channel for kinetic feedback from accreting black holes into their environment, without which models of the formation of large-scale structure in the univ…
On the distance to the black hole X-ray binary Swift J1727.81613
Benjamin J. Burridge, James C. A. Miller-Jones, Arash Bahramian +11
We review the existing distance estimates to the black hole X-ray binary Swift J1727.81613, present new radio and near-UV spectra to update the distance constraints, and discuss…
Enhanced detection and identification of satellites using an all-sky multi-frequency survey with prototype SKA-Low stations
Dylan Grigg, Steven Tingay, Steve Prabu +2
With the low Earth orbit environment becoming increasingly populated with artificial satellites, rockets, and debris, it is important to understand the effects they have on radio a…
The Subparsec-scale Structure and Evolution of Centaurus A. III. A Multi-Epoch Spectral And Polarimetric VLBA Study
Steve Prabu, Steven J Tingay, Arash Bahramian +3
The Centaurus A radio galaxy, due to its proximity, presents itself as one of the few systems that allow the study of relativistic jet outflows at sub-parsec distances from the cen…
Swift J1727.8-1613 has the Largest Resolved Continuous Jet Ever Seen in an X-ray Binary
Callan M. Wood, James C. A. Miller-Jones, Arash Bahramian +21
Multi-wavelength polarimetry and radio observations of Swift J1727.8-1613 at the beginning of its recent 2023 outburst suggested the presence of a bright compact jet aligned in the…
A Near-Field Treatment of Aperture Synthesis Techniques using the Murchison Widefield Array
Steve Prabu, Steven J. Tingay, Andrew Williams
Typical radio interferometer observations are performed assuming the source of radiation to be in the far-field of the instrument, resulting in a two-dimensional Fourier relationsh…
Detection of intended and unintended emissions from Starlink satellites in the SKA-Low frequency range, at the SKA-Low site, with an SKA-Low station analog
Dylan Grigg, Steven Tingay, Marcin Sokolowski +3
Intended and unintended radio emissions from satellites can interfere with sensitive radio telescopes in the frequency ranges of key experiments in astrophysics and cosmology. We d…
Demonstration of Orbit Determination for LEO Objects using the Murchison Widefield Array
S. Prabu, P. Hancock, X. Xiang +1
The rapidly increasing number of satellites in Earth's orbit motivates the development of Space Domain Awareness (SDA) capabilities using wide field-of-view sensor systems that can…
Improved Sensitivity for Space Domain Awareness Observations with the Murchison Widefield Array
Steve Prabu, Paul J Hancock, Xiang Zhang +4
Our previously reported survey of the Low Earth Orbit (LEO) environment using the Murchison Widefield Array (MWA) detected over 70 unique Resident Space Objects (RSOs) over multipl…
The GLEAMing of the first supermassive black holes: II. A new sample of high-redshift radio galaxy candidates
J. W. Broderick, G. Drouart, N. Seymour +27
While unobscured and radio-quiet active galactic nuclei are regularly being found at redshifts , their obscured and radio-loud counterparts remain elusive. We build upon our…
A Low Frequency Blind Survey of the Low Earth Orbit Environment using Non-Coherent Passive Radar with the Murchison Widefield Array
Steve Prabu, Paul J Hancock, Zhang Xiang +1
We have extended our previous work to use the Murchison Widefield Array (MWA) as a non-coherent passive radar system in the FM frequency band, using terrestrial FM transmitters to…
The Development of Non-coherent Passive Radar Techniques for Space Situational Awareness with the Murchison Widefield Array
Steve Prabu, Paul J Hancock, Xiang Zhang +1
The number of active and non active satellites in Earth orbit has dramatically increased in recent decades, requiring the development of novel surveillance techniques to monitor an…
