  "abstract": "We report the detailed spectral measurements over a wide frequency range of three pulsars: J1741-3016, J1757-2223 and J1845-0743, using the Giant Metrewave Radio Telescope, which allowed us to identify them as a new gigahertz-peaked spectra pulsars. Our results indicate that their spectra show turnovers at frequencies of 620 MHz, 640 MHz and 650 MHz, respectively. Our analysis proves that wide-band observations improve the estimation of the spectral nature using a free-free thermal absorption model and thus allow a more accurate approximation of the maximum energy in the spectrum. While there is no evidence as of yet that these objects are associated with a supernova remnant or pulsar wind nebula, they are good targets for looking for interesting environments in the future, more sensitive sky surveys.",
