Abstract:
In the framework of the Standard Model Extension (SME), we present
improved constraints on anisotropic Lorentz invariance and
Charge-Parity-Time (CPT) violation by searching for astrophysical
signals of cosmic vacuum birefringence with broadband optical
polarimetry of high redshift astronomical sources, including Active
Galactic Nuclei and Gamma-Ray Burst afterglows. We generalize Kislat
(Constraints on lorentz invariance violation from optical polarimetry
of astrophysical objects. Symmetry, 10(11), 2018. ISSN 2073-8994.
doi:10.3390/sym10110596), which studied the SME mass dimension d=4
case, to arbitrary mass dimension for both the CPT-even and CPT-odd
cases. We then present constraints on all 10, 16, and 42 anisotropic
birefringent SME coefficients for dimension d=4, d=5, and d=6 models
respectively, using 7554 observations for odd d and 7376 observations
for even d of 1278 unique sources on the sky, which, to our knowledge
comprises the most complete catalog of optical polarization from
extragalactic sources in the literature to date. Compared to the
smaller sample of 44 and 45 broadband optical polarimetry observations
analyzed in Kislat (Constraints on lorentz invariance violation from
optical polarimetry of astrophysical objects. Symmetry, 10(11), 2018.
ISSN 2073-8994. doi:10.3390/sym10110596) and Kislat et al. (2017
Phys. Rev. D, 95(8):083013, doi: 10.1103/PhysRevD.95.083013), our
dimension d=4 and d=5 average constraints are more sensitive by
factors of 35 and 10, corresponding to a reduction in allowed SME
parameter space volume for these studies of 15 and 16 orders of
magnitude, respectively. Constraints from individual lines of sight
can be significantly stronger using spectropolarimetry, due to the
steep energy dependence of birefringence effects at increasing mass
dimension. Nevertheless, due to the increased number of observations
and lines of sight in our catalog, our average d=4 and d=5 broadband
constraints are within factors of 2 and 12 of previous constraints
using spectropolarimetry from Kislat (Constraints on lorentz
invariance violation from optical polarimetry of astrophysical
objects. Symmetry, 10(11), 2018. ISSN 2073-8994.
doi:10.3390/sym10110596) and Kislat et al. (2017, Phys. Rev. D
95(8):083013, doi: 10.1103/PhysRevD.95.083013), respectively, using an
independent data set and an improved analysis method. By contrast, our
anisotropic constraints on all 42 birefringent SME coefficients for
d=6 are the first to be presented in the literature.
Description:
The 7554 linear broadband optical polarization measurements and 7376
polarization angle measurements of 1278 extragalactic sources from the
literature, which comprises the most comprehensive such optical
polarization database in the literature to date, used to constrain
anisotropic Lorentz invariance and CPT violation in the context of the
Standard Model Extension are presented.
