Jets from a hungry black hole blaze with the power of 10,000 suns

Astronomers using the Square Kilometre Array measured jets blasting from the Cygnus X-1 black hole as it siphons material from a blue supergiant companion. The jets carry about 10% of the energy of the infalling matter and emit as much energy as 10,000 suns, with speeds around half the speed of light. The finding provides a robust anchor for jet power in black holes and helps calibrate how these jets influence galaxies across the cosmos.

Square Kilometre Array's Data Center Uses Dual Faraday Cages to Prevent RF Leaks

The SKA's datacenter in Western Australia, nearly complete, is protected by two Faraday cages to prevent RF leaks that could interfere with the world's largest radio telescope, which aims to explore the universe with unprecedented sensitivity. The project involves extensive antenna installation and will continue until 2029, with scientific proposals starting in 2024 and initial tests in 2027.

"Filtering Satellite Interference for Square Kilometre Array Precursor"

The Australian Square Kilometre Array Pathfinder (ASKAP) is developing techniques to mitigate satellite interference as it copes with increased satellite traffic, particularly in the bands used for its observations. The project's head of data operations, Dr. Matthew Whiting, highlighted concerns about the impact of satellite signals on ASKAP's operations and discussed efforts to predict and mitigate interference. ASKAP's use of Pawsey's "Setonix" supercomputer has also presented challenges due to the project's high data rate, producing four terabytes an hour at its peak.

"SKA Prototype Telescope Achieves First Light, Revealing Milky Way Core"

The Square Kilometre Array's radio telescope prototype, SKAMPI, has achieved first light in South Africa, demonstrating its spectral and pulsar capabilities by capturing the Southern sky at 2.5GHz wavelength. The telescope's success will inform the development of the 197-dish SKA-Mid telescope and the construction of the SKA-Low facility in Australia. India has also recently become a full member of the Square Kilometre Array project.

Unveiling Dark Matter: The 21-cm Forest Probe's Cosmological Revolution

A joint research team has proposed using the 21-cm forest probe to study dark matter and the formation of early galaxies simultaneously. This novel approach, made possible by the ongoing Square Kilometre Array project and the discovery of high-redshift radio-loud quasars, could provide insights into the thermal history of the universe and help constrain dark matter properties. The 21-cm forest probe, which measures the 1-D power spectrum of atomic hydrogen gas, offers a viable means of understanding dark matter and the first galaxies beyond the reach of other observations.
