Many TDEs can be found in dusty galaxies. Dust obscures many wavelengths of radiation, from optical to X-rays, but long infrared wavelengths are much less susceptible to scattering and absorption. When the team checked galaxies in the infrared, they found 18 TDEs that had eluded astronomers before.
Most of the TDEs discovered by the research team had not previously been detected in the optical band by the WISE or NEOWISE infrared observatory mission. When they looked for these events in data from NASA's WISE (Wide-Field Infrared Survey Explorer) and NEOWISE missions, along with data from other mission
