On February 18, 2006, Soderberg was a member of a group of researchers who detected the gamma-ray burstGRB 060218 located 440 million light years (135 Mpc) away in the constellation Aries. The detection of the associated supernova SN2006aj provided one of the best evidence to date tying gamma-ray bursts and supernovae.[3]
Soderberg and her colleagues detected the supernova SN 2008D as it was occurring on January 9, 2008, using data from NASA's Swift Gamma-Ray Burst MissionX-rayspace telescope, from a precursor star in the spiral galaxyNGC 2770, 88 million light years away (27 Mpc). They alerted eight other orbiting and ground-based observatories to record the event.[4][5] The team was able to catch the supernova in action because they had been making observations of NGC 2770 to observe supernova SN 2007uy.[6]
