Summary
This summary is machine-generated.

Researchers set direct upper limits on gravitational waves from 28 radio pulsars using LIGO data. This study provides the first direct upper limits for 26 pulsars, constraining their shapes.

Area of Science:

  • * Astrophysics
  • * Gravitational Wave Astronomy
  • * Pulsar Physics

Background:

  • * Isolated radio pulsars are potential sources of continuous gravitational waves.
  • * Detecting these waves requires sensitive instruments like the Laser Interferometer Gravitational-Wave Observatory (LIGO).
  • * Previous searches for pulsar gravitational waves have relied on less precise methods.

Purpose of the Study:

  • * To establish direct upper limits on the amplitude of gravitational waves emitted by 28 isolated radio pulsars.
  • * To utilize coordinated radio observations for improved gravitational wave signal detection.
  • * To constrain the physical properties, such as ellipticity, of these pulsars.

Main Methods:

  • * Coherent multidetector analysis of data from the second LIGO science run.

  • * Development and application of radio-guided phase templates for gravitational wave signal matching.
  • * Direct upper limit setting on gravitational wave strain.

    • Main Results:

    • * Direct upper limits on gravitational wave amplitudes were placed for 28 isolated radio pulsars.
    • * These represent the first direct upper limits for 26 of the studied pulsars.
    • * Strain upper limits reached levels as low as a few times 10^-24.
    • * Equatorial ellipticities were constrained to be less than 10^-5 for the four nearest pulsars.

    Conclusions:

    • * The study successfully established new direct upper limits on gravitational waves from isolated radio pulsars.
    • * The use of radio-guided templates significantly enhanced the search sensitivity.
    • * The results provide valuable constraints on the astrophysical properties of pulsars.
