Glitches can mildly bias EMRI inference in LISA
What the study found Streams of transient, non-Gaussian noise artifacts called glitches can bias inference for extreme mass ratio inspirals (EMRIs) in the Laser Interferometer Space Antenna (LISA), but the effect is relatively small when the glitches are moderately mitigated. The study found that EMRI inference is more robust to glitches than inference for some…
Method reduces uncertainty in precision two-body mass measurements
—
What the study found The study found that detector-related uncertainties can be analyzed more rigorously by looking at how observed mass shifts depend on the sum and difference of the daughter particle momenta in two-body decays. The authors applied this idea to the Λ hyperon (a particle made of one up quark, one down quark,…
