Guessing that a ultrasonic microphone from a bioaccoustics site should fit the bill - otherwise, what could researchers pick themselves?
This one, for example, picks up to 200kHz for €1050:

It should be on the materials & methods section of the papers.
I hope it doesn't go all the way to 200khz. Consumer audio can go up to a 192kHz sampling rate, which can't even record 100 kHz sounds.
It seems the equipment will be costly.
