| 英文摘要 | We search for the isotropic stochastic gravitational-wave background, including the nontensorial polarizations that are allowed in general metric theories of gravity, in the Parkes Pulsar Timing Array (PPTA) second data release (DR2). We find no statistically significant evidence that the common-spectrum process reported by the PPTA collaboration has tensor transverse, scalar transverse, vector longitudinal, or scalar longitudinal correlations in PPTA DR2. Therefore, we place a 95% upper limit on the amplitude of each polarization mode, as ATT less than or similar to 3.2 x 10(-15), A(ST) less than or similar to 1.8 x 10(-15,) A(VL) less than or similar to 3.5 x 10(-16), and A(SL) less than or similar to 4.2 10(-17) or, equivalently, a 95% upper limit on the energy density parameter per logarithm frequency, as Omega(TT)(GW) less than or similar to 1.4 10(-8), Omega(ST)(GW) less than or similar to 4.5 x 10(-9), Omega(VL)(GW) less than or similar to 1.7 x 10(-10), and Omega(SL)(GW) less than or similar to 2.4 x 10(-12), at a frequency of 1/yr. |
