ANDES, The High Resolution Spectrograph For The ELT: Science Goals, Project Overview And Future Developments
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph).

Replication of Filtered Interferometer Measurements In Interstellar Communications
Interstellar communication signals have been conjectured to be present, albeit difficult to identify. Experiments conducted since 2018 indicate an anomalous presence of a type of speculated interstellar signal, delta-t delta-f […]
