Errors quoted on results are often given in asymmetric form. An account is given of the two ways these can arise in an analysis, and the combination of asymmetric errors is discussed. It is shown that the usual method has no basis and is indeed wrong. For asymmetric systematic errors, a consistent method is given, with detailed examples. For asymmetric statistical errors a general approach is outlined.

  1. Searches for CE{\nu}NS and Physics beyond the Standard Model using Skipper-CCDs at CONNIE

    hep-ex 2024-03 unverdicted novelty 7.0 of 10

    CONNIE's first Skipper-CCD run at Angra-2 yields no CEνNS excess, comparable prior limits on neutrino rates, improved bounds on light vector mediators, and record surface DM-electron limits via diurnal modulation.

  2. Magnetic excitations and interactions in the Weyl ferrimagnet NdAlSi

    cond-mat.str-el 2024-12 conditional novelty 6.0 of 10

    Measurements of magnetic excitations in NdAlSi reveal sign-changing exchange interactions and show that a low-symmetry DM interaction, not Weyl-node symmetry, stabilizes the helical spin spiral.

  3. Physical characterization of the FeLoBAL outflow in SDSS J0932+0840: Analysis of VLT/UVES observations

    astro-ph.GA 2024-12 conditional novelty 6.0 of 10

    A FeLoBAL outflow in quasar J0932+0840 has hydrogen density 10^4.8 cm^-3, lies at 0.7 kpc from the black hole, and its kinetic luminosity is only about 0.5e-4 of Eddington, so it does not contribute significant AGN feedback.

  4. The impact of source and survey modelling on the connection between [O III] emitters and Ly $\alpha$ forest transmission at z ~ 6

    astro-ph.CO 2026-06 unverdicted novelty 5.0 of 10

    Empirical halo-to-[O III] emitter modeling with realistic JWST survey mocks produces cross-correlations consistent with z~6 data within large scatter, but with a ~10 cMpc offset in the 1D peak.

  5. On the impact of magnetic-field models in galaxy clusters on constraints on axion-like particles from the lack of irregularities in high-energy spectra of astrophysical sources

    astro-ph.HE 2019-08 conditional novelty 5.0 of 10

    For a purely regular magnetic field in the X-ray cavity of NGC 1275, the ALP-photon coupling constraints from Fermi-LAT spectral smoothness are much weaker than for the purely turbulent field assumed in previous work,...
