The Birth of a Relativistic Outflow in the Unusual γ-ray Transient Swift J164449.3+573451
B. A. Zauderer, E. Berger, A. M. Soderberg +24
Active galactic nuclei (AGN), powered by long-term accretion onto central supermassive black holes, produce relativistic jets with lifetimes of greater than one million yr that pre…

A Relativistic Type Ibc Supernova Without a Detected Gamma-ray Burst
A. M. Soderberg, S. Chakraborti, G. Pignata +21
Long duration gamma-ray bursts (GRBs) mark the explosive death of some massive stars and are a rare sub-class of Type Ibc supernovae (SNe Ibc). They are distinguished by the produc…

An extremely luminous X-ray outburst at the birth of a supernova
A. M. Soderberg, E. Berger, K. L. Page +40
Massive stars end their short lives in spectacular explosions, supernovae, that synthesize new elements and drive galaxy evolution. Throughout history supernovae were discovered ch…
