Radio pulsar beam geometry down to the 100-MHz band: 76 additional sources within the Arecibo Sky

ABSTRACT This paper provides analyses of the emission beam structure 76 ‘B’-named pulsars within Arecibo sky. Most these objects are included in both Gould & Lyne and LOFAR High Band surveys thus complement our other works treating various parts populations. These comprise a further group mostly well-studied sky that we here treat similarly to those Olszanski et al. – extend overall efforts study all surveys. The based on observations made with Telescope at 327 MHz 1.4 GHz. Many have been observed frequencies down 100 using either or Pushchino Radio Astronomy Observatory as well few Long Wavelength Array lower frequencies. work uses foundation for interpreting low frequency profiles emission-beam geometries. We attempt build quantitative geometric models core/double-cone topology, while reviewing evidence previous studies arguments classifications sources. were successful but two pulsars, interesting new subpulse modulation patterns identified number objects. interpret pulsar population context entire ‘B’ pulsars.
