human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "hunting for supernovae articles in the universe of scientometrics"):
  Abstract: This short note records an unusual situation with some Google Scholar's profiles that imply the existence of "supernovae" articles, i.e., articles whose impact -- in terms of number of citations -- in a single year gets (almost) an order of magnitude higher than the previous year and immediate drops (and remains steady) to a very low level after the next year. We analyse the issue and resolve the situation providing an answer whether there exist supernovae articles.
