TXS 0506+056 and IceCube-170922A: what remains open
Question
What remains open in the association of IceCube-170922A with TXS 0506+056?
Answer
The strongest single blazar candidate, not yet a definitive identification.
- IceCube-170922A, a ~290 TeV track during a gamma-ray flare: about 3–3.5σ.
- 2014–15 archival excess of 13 ± 5 events: about 3.5σ, with PKS 0502+049 1.2° away as a possible contributor.
- One-zone hadronic models are strongly disfavored for the 2014–15 flare: they overproduce X-rays or need 1050–1052 erg s−1.

How this answer was made
The ideation agent compared the published evidence for the association with what emission models allow, and listed where they disagree. The answer cites papers for its statements, and each reference links to its NASA ADS record. The full answer cites 9 papers; four are shown here.
