The paper presents a new method for inverting polyphase filter banks using a circulant formalism and FFT-based algorithm, enabling high-resolution spectral analysis in radio astronomy with effective quantization noise mitigation.
A tiny UK-developed satellite, CosmoCube, will use the far side of the Moon as a shield to detect faint signals from the early universe, aiming to study the cosmic dark ages and the role of dark matter.
An Australian teen team has developed an affordable radio astronomy system to make the field accessible to schools, particularly in rural areas.
