Research Gap Sky Map
Where are the observational gaps in astronomy? Each dot is an astronomical object, colored by how many suitable observational methods have never been applied to it.
Theory Gap Matrix
Which observational methods could validate theoretical predictions, but have few papers? Rows are theory domains, columns are observational methods. Color intensity shows paper count; red borders mark gaps (suitable method, zero papers).
Suitability Matrix
Which observational methods are suitable for which object types? This matrix is the basis of the gap analysis above. Green = suitable, yellow = conditional, striped = unsuitable.
