I want to explain my problem by the following sentence.
Among those scientists recently exploring 'terra cognita' were psychologists from the State University of New York at Stony Brook.
In that sentence, what is the subject of the auxiliary verb "were"? I think, subject of auxiliary verb is 'there' and it has been omitted in this sentence. Am I right?
If I wish to place 'that/who' before the word 'exploring' in that sentence, will it be legal? And if I do this, the form of 'exploring' will be 'explore'. Am I right?
