The idea of neutron stars was conceived in the 1930s by Walter Baden and Fritz Zwicky, who collaborated to be perhaps the most important forecast in the history of astronomy, with the radical proposal of the possibility of a supernova representing the transition from a common star to a neutron star. In 1967, Jocelyn Bell, from the University of Cambridge, detected precisely periodic pulses coming from the sky, where she believed to be from an extraterrestrial civilization that she called Little Green Man, in December of the same year she found another pulsating radio source and claimed it was a natural radio source from our galaxy. Pulsars are magnetized neutron stars that appear to emit periodic short pulses of radio radiation, such an object is similarly compared to a beacon, they emit rotating beams of radiation continuously and appear to blink each time the beam passes through the observer's line of sight. It is relevant for the study of pulsars to highlight some important physical properties that are: rotation periods; mass and radius; spindonw luminosity; magnetic dipole radiation; characteristic age; dispersion measures. We have covered some general information about the BINGO radio telescope. We made a sketch of the celestial map using pulsed data from ATNF with the settings adapted for BINGO. Finally, we show the schematic of a mini radio telescope that is being built at UFCG, which will be coupled to the CALLISTO spectrometer to measure pulsar signals.
