![Schematic of the flow-map encoder–operator–decoder architecture used to emulate chemical kinetics. The encoder maps the current normalized input state (and global parameters) to a latent space. The latent dynamics operator evolves this latent state using the time step and global parameters, and the decoder reconstructs the predicted future normalized species state. Optional residual connections can be applied in latent space and/or on the normalized model outputs.-- astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Accelerating.png?resize=1200%2C718&ssl=1)

Accelerating Chemical Kinetics For Exoplanet Atmospheres Using Neural Networks
[astro-ph.EP] Observations increasingly reveal the coupled radiative, chemical, and dynamical processes that shape exoplanet atmospheres. Interpreting these atmospheres requires models that can capture this complexity.

pyEDITH: The Coronagraphic Exposure Time Calculator For The Habitable Worlds Observatory
[astro-ph.IM] To support the development of next-generation missions for the search and characterization of habitable planets, high-fidelity tools for astrophysical and instrumental noise simulations are needed.
![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)

Slysh Haloes: The Waste Heat Of Cold Computing As A Submillimetre Technosignature
[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 […]
