  • The radio properties of 4C21.53 have been an enigma for many years. First, the object displays interplanetary scintillations (IPS) at 81 MHz, indicating structure smaller than 1 are s, despite its low galactic latitude (−0.3°)1. IPS modulation is rare at low latitudes because of interstellar angular broadening. Second, the source has an extremely steep (∼v−2) spectrum at decametric wavelengths2. This combination of properties suggested that 4C21.53 was either an undetected pulsar or a member of… CONTINUE READING
