Joint probes
Think of it like solving a puzzle with multiple pieces. The neutrino detectors might say, "Hey, we heard something!" but then the CMB experiments could say, "Wait, let me look again." And together, using both clues, they can put all the pieces together and uncover what this mysterious dark matter is.
Technical definition
A method of combining multiple observational datasets or experimental techniques to achieve greater precision and confidence in scientific conclusions than any single dataset or technique alone.
