Constraints on Lorentz violation from gravitational Cerenkov radiation
Limits on gravitational Cerenkov radiation by cosmic rays are obtained and used to constrain coefficients for Lorentz violation in the gravity sector associated with operators of even mass dimensions, including orientationdependent effects. We use existing data from cosmicray telescopes to obtain conservative twosided constraints on 80 distinct Lorentzviolating operators of dimensions four, six, and eight, along with conservative onesided constraints on three others. Existing limits on the nine minimal operators at dimension four are improved by factors of up to a billion, while 74 of our explicit limits represent stringent first constraints on nonminimal operators. As a result, prospects are discussed for future analyses incorporating effects of Lorentz violation in the matter sector, the role of gravitational Cerenkov radiation by highenergy photons, data from gravitationalwave observatories, the tiredlight effect, and electromagnetic Cerenkov radiation by gravitons.
