Abstract: The background power spectral density (PSD) of underwater acoustic signals carries important information about the environment. However, loud transients from human or natural sources are ...

Abstract: Spectral redshift navigation (SRN) is an emerging navigation method for deep space exploration, where the redshifts of spectral signal are taken as the measurements in Kalman filtering to ...

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

Replaced the XSL SSP models with those embedded with the pPXF distribution in .npz format. These templates are automatically downloaded by SPAN the first time they are called in the "Stars and gas ...
