Narrative:

While on a training flight and on final approach to runway 32 at 800 ft. MSL (700 ft. AGL) it was noticed on my ads-B in that there was a traffic conflict with another aircraft at an altitude 100 ft. Above me going to the intersecting runway 27.I made numerous attempts to call the aircraft by the tail number that their ads-B out was reporting.after numerous attempts were made with no response and at 400 ft. MSL (300 ft. AGL) on short final I made the decision to go around. The FBO had heard the exchange and reported to this writer that when she advised the aircraft Y crew that another aircraft went around due to them not talking on the radio they made the statement to the effect of 'we didn't know where to find the frequency and the tower is closed'.after the flight and finding out this information I conducted a ground with my student to make it a teaching moment of 91.103 and 91.13. I explained how 91.103 requires the PIC to be familiar with all pertinent airport information. That we as the PIC need to do our due diligence in not putting others or the general public at risk and that the go around was the safest option while keeping aircraft Y in sight in case they rejected their landing. I also explained to the student that while radio communications at a pilot controlled field are not required it could be conceived by others that it could be a violation of 91.13 by being careless in not using radios when they are equipped and not giving right of way to the aircraft that is lower than you on an intersecting runway.
