Swift J164449.3+573451 event: generation in the collapsing star cluster?

, 2012
We discuss the multiband energy release in a model of a collapsing galactic nucleus, and we try to interpret the unique super-long cosmic gamma-ray event Swift J164449.3+573451 (GRB 110328A by early classification) in this scenario.
