Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency ...

Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, ...

In the Crab Nebula, a rapidly rotating neutron star, or pulsar (white dot near the center), powers the dramatic activity seen by Chandra. The inner X-ray ring is thought to be a shock wave that marks ...

Constraining the origin of the nanohertz gravitational-wave background necessitates precise noise modelling to avoid parameter estimation biases. In this work, we find the inferred properties of the ...
