Observation, Signal & Reconstruction
Begin with what a detector actually receives. These four themes separate source history, propagation history, receiver response and model-based reconstruction.

01
What Do We Actually Observe?
Measurement begins with radiation received here. Source history is reconstructed through a causal and mathematical chain.
02Redshift: Source History or Signal History?
The shift is measured. The physical story assigned to it belongs to a model.
03Supernova Duration and the Shape of the Signal
Spectral redshift and the longer light curve are frequency-domain and time-domain descriptions of one coherent scaling.
04The Soft Horizon: The Edge of Knowing
A source may remain detectable after its surviving signal no longer determines one unique source history.
