Question
An early success in this field of astronomy involved observations of neutrinos, then optical light, then X-rays and gamma rays in 1987. For 10 points each:
[10h] Name this nascent field of astronomy that studies sources by observing “multi” namesake modes of data describing different types of emission from the same source.
ANSWER: multi-messenger astronomy
[10e] That 1987 event was a “type II” example of these enormous explosions of dying stars.
ANSWER: supernovae [accept type II supernovae or supernova 1987 A; prompt on SNs or SN 1987 A; accept supernovas in place of “supernovae”]
[10m] Different “messengers” from the same source can arrive at different times due to interactions with this phenomenon, like in the mechanism of the GZK limit. Penzias and Wilson discovered this universe-filling phenomenon.
ANSWER: cosmic microwave background radiation [or CMBR; prompt on microwave background or MBR] (The GZK limit is due to interactions between protons and the CMBR.)
