I describe a colour scheme that is appropriate for the screen display of intensity images. This -- unlike many currently available schemes -- is designed to be monotonically increasing in terms of its perceived brightness. Also, when printed on a black and white postscript printer, the scheme results in a greyscale with monotonically increasing brightness. This scheme has recently been incorporated into the radio astronomical analysis packages CASA and AIPS.

  1. The Rapid ASKAP Continuum Survey VII: Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) Second Data Release -- Unveiling the Magnetised Sky

    astro-ph.GA 2026-05 unverdicted novelty 6.0 of 10

    SPICE-RACS DR2 produces the largest single Faraday rotation measure catalog to date from RACS-low3 observations, with 2.5e5 RMs at 6.7 per square degree over most of the southern sky.

    astro-ph.GA 2026-05 unverdicted novelty 6.0 of 10

    SPICE-RACS DR2 delivers the largest single Faraday rotation measure catalog from a radio survey, with 250,000-340,000 RMs across most of the sky at median uncertainty of 2 rad m^{-2}.

  3. The $M_{\rm BH}$$-$$R_{\rm b}$ relation and the high-mass end of the $M_{\rm BH}$$-$$\sigma$ relation

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

    Updated M_BH-R_b relation for core-Sérsic galaxies has slope 1.16 and 0.28 dex scatter; large-core galaxies drive a high-mass upturn in M_BH-σ attributed to successive dry mergers.

  4. Line-of-sight shear in SLACS strong lenses II: validation tests with an extended sample

    astro-ph.CO 2025-12 conditional novelty 4.0 of 10

    Line-of-sight shear in 45 SLACS lenses is often larger than N-body expectations (mean |γ_LOS| ≈ 0.085–0.11), and adding mass octupoles or checking image properties does not remove the excess.
