Abstract
In this paper, we present results from flux-density measurements for 21 pulsars over a wide frequency range, using the Giant Metrewave Radio Telescope (GMRT) and the Effelsberg telescope. Our sample was a set of mostly newly discovered pulsars from the selection of candidates for gigahertz-peaked spectra (GPS) pulsars. Using the results of our observations along with previously published data, we identify two new GPS pulsars. One of them, PSR J1740+1000, with dispersion measure (DM) of 24 pc cm$^{−3}$, is the first GPS pulsar with such a low DM value. We also selected several strong candidates for objects with high-frequency turnover in their spectra, which require further investigation. We also revisit our source selection criteria for future searches for GPS pulsars.
