Abstract
We present a search for gravitational waves from 222 pulsars with rotation frequencies ≳10 Hz. We use advanced LIGO data from its first and second observing runs spanning 2015–2017, which provides the highest-sensitivity gravitational-wave data so far obtained. In this search we target emission from both the l = m = 2 mass quadrupole mode, with a frequency at twice that of the pulsar's rotation, and the l = 2, m = 1 mode, with a frequency at the pulsar rotation frequency. The search finds no evidence for gravitational-wave emission from any pulsar at either frequency. For the l = m = 2 mode search, we provide updated upper limits on the gravitational-wave amplitude, mass quadrupole moment, and fiducial ellipticity for 167 pulsars, and the first such limits for a further 55. For 20 young pulsars these results give limits that are below those inferred from the pulsars' spin-down. For the Crab and Vela pulsars our results constrain gravitational-wave emission to account for less than 0.017% and 0.18% of the spin-down luminosity, respectively. For the recycled millisecond pulsar J0711−6830 our limits are only a factor of 1.3 above the spin-down limit, assuming the canonical value of 10^(38) kg m^2 for the star's moment of inertia, and imply a gravitational-wave-derived upper limit on the star's ellipticity of 1.2 × 10^(−8). We also place new limits on the emission amplitude at the rotation frequency of the pulsars.

This work has been assigned LIGO document number LIGO-P1800344. Facilities: Arecibo - Arecibo observatory, Fermi - , LIGO - , Lovell - , Molonglo Observatory - , MtPO:26 m - , NICER - , NRT - , Parkes. - Software: Much of the analysis described in the paper was performed using the publicly available LALSuite library (LIGO Scientific Collaboration 2018). Production of many of the pulsar timing ephemerides used in this analysis was performed with Tempo206 and Tempo2 (Hobbs et al. 2006b).
