Normalized torques as a function of planetary mass and semimajor axis, assuming circular and coplanar orbits. The different migration regimes are indicated, separating inward from outward migration. The mass required

Graphical Abstract Viruses play essential roles in shaping the structure and function of microbial communities, including those inhabiting extreme environments. The Qaidam Basin is a unique Mars-analog desert characterised by

Peak emission wavelength of a Dyson Swarm as a function of swarm temperature, following Wien’s displacement law, λmax = b/TDS. The shaded regions indicate the approximate wavelength coverage of key
