![Waste-heat temperature–luminosity phase space. Existing midinfrared searches occupy the warm band (orange); cold computational radiators fall in the far-infrared/submillimetre band (green) towards the CMB floor. Grey lines show 345-GHz flux-density contours for a source at 100 pc, from equation (10), which is linear in the fractional waste-heat luminosity 𝑓 on the vertical axis; the figure thus covers partial swarms and complete spheres (𝑓 = 1) alike. Markers indicate a complete 1 L⊙ cold sphere, the level of the archival debris-survey limits (Section 6.1), and the domain of warm mid-infrared searches. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Slysh.png?resize=1200%2C720&ssl=1)
[astro-ph.IM] Searches for Dysonian waste heat have operated almost exclusively in the mid-infrared and are therefore sensitive primarily to technology radiating at 100-600K. We argue that mature, computation-dominated civilisations may […]

Observations Of Low-mass Protostellar Systems Show Evidence Of Rich Complex Organic Chemistry.
Observations of low-mass protostellar systems show evidence of rich complex organic chemistry. Their low luminosity, however, makes determining abundance distributions of complex organic molecules (COMs) within the water snowline challenging.
