Description
The third-generation gravitational-wave detector Einstein Telescope will observe a large population of compact binary coalescences (CBCs), whose superposition is expected to form an unresolved astrophysical background, particularly relevant at low frequencies. This foreground may affect searches for continuous gravitational waves (CWs) from spinning neutron stars.
In this work, we investigate the impact of the unresolved CBC background on CW searches with the Einstein Telescope. Using realistic simulations of the unresolved CBC population, we analyze its effect on CW signals with the Frequency Hough pipeline, focusing on the low-frequency band: [2,256]Hz.
Our results indicate that the presence of the CBC foreground effectively acts as an additional noise source, reducing CW detection efficiency, with the strongest impact observed around 7 Hz.
