ADC_Keywords: Pulsars ; Radio continuum ; Surveys Keywords: catalogs; gamma rays: general; pulsars: general; radio continuum: general; surveys Abstract: We have used the 150MHz radio continuum survey (TGSS ADR) from the Giant Metrewave Radio Telescope (GMRT) to search for phase-averaged emission toward all well-localized radio pulsars north of -53° decl. We detect emission toward 200 pulsars with high confidence (≥5σ) and another 88 pulsars at fainter levels. We show that most of our identifications are likely from pulsars, except for a small number where the measured flux density is confused by an associated supernova or pulsar-wind nebula, or a globular cluster. We investigate the radio properties of the 150MHz sample and find an unusually high number of gamma-ray binary millisecond pulsars with very steep spectral indices. We also note a discrepancy in the measured flux densities between GMRT and LOFAR pulsar samples, suggesting that the flux density scale for the LOFAR pulsar sample may be in error by approximately a factor of two. We carry out a separate search of 30 well-localized gamma-ray, radio-quiet pulsars in an effort to detect a widening of the radio beam into the line of sight at lower frequencies. No steep-spectrum emission was detected either toward individual pulsars or in a weighted stack of all 30 images. Description: The GMRT was used to carry out a radio continuum survey at a frequency of 150MHz using a total of 2000hr of observations. The entirety of these data have recently been reprocessed (Giant Metrewave Radio Telescope (GMRT) 150MHz all-Sky radio Survey; TGSS ADR, Intema+ 2016arXiv160304368I), creating high-quality images of approximately 90% of the entire sky. The TGSS ADR achieves a median rms noise level of 3.5mJy/beam and an angular resolution of 25" for decl.>19°, and 25"x25"/cos(decl.-19°) for more southern decl. LOFAR has carried out a search for pulsed emission from all northern radio pulsars (Bilious+ 2016A&A...591A.134B; Kondratiev+ 2016A&A...585A.128K). This census was primarily conducted with the LOFAR high-band antennas (HBAs) between 110 and 188MHz, with 400 channels each of 0.195MHz in width, or a bandwidth of 78MHz. We find 92 pulsars commonly detected in both the LOFAR and TGSS ADR surveys (Tables 1 and 2). File Summary:
