Over the last few years, the number of known eclipsing radio millisecond pulsar systems in the Galactic field has dramatically increased, with many being associated with Fermi gamma-ray sources. All are in tight binaries (orbital period < 24 hr) with many being classical "black widows" which have very low mass companions (companion mass Mc << 0.1 Msol) but some are "redbacks" with low mass (Mc ~ 0.2 - 0.4Msol) companions which are probably non-degenerate. These latter are systems where the mass transfer process may have only temporarily halted, and so are transitional systems between low mass X-ray binaries and ordinary binary millisecond pulsars. Here we review the new discoveries and their multi-wavelength properties, and briefly discuss models of shock emission, mass determinations, and evolutionary scenarios.

  1. Coherent Signal Detection with Pruning -- I. Finding Short-Period Binary Pulsars in Circular Orbits

    astro-ph.HE 2026-07 conditional novelty 8.0

    A hierarchical pruning framework reduces the computational cost of fully coherent circular-orbit binary pulsar searches by up to 10 orders of magnitude, enabling sensitivity 3-5x better than acceleration searches.

  2. An Acceleration is Worth a Hundred Thousand Phase Space Measurements

    astro-ph.GA 2026-06 unverdicted novelty 7.0

    One acceleration measurement equals ~10^5 phase-space measurements for local dark matter density estimation, with acceleration outperforming Jeans modeling in both equilibrium and perturbed Milky Way simulations.

  3. A new likely pulsar binary in 47~Tucanae from continuum searches

    astro-ph.HE 2026-07 conditional novelty 6.0

    47 Tuc W41 is a redback millisecond-pulsar binary with Lx ~ 3e31 erg/s, steep-spectrum radio continuum, and an irradiated ~0.5 Msun secondary on a 10.4-hr orbit.

  4. Understanding the Neutron Star Population with the SKAO Telescopes

    astro-ph.HE 2026-07 accept novelty 3.5

    SKAO AA* and AA4 surveys are projected to discover thousands of ordinary pulsars and ~800–1000 MSPs, enabling population synthesis, mass measurements and tests of gravity and emission physics.

  5. Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO

    astro-ph.HE 2026-07 accept novelty 3.5

    SKAO's sensitivity, surveys and sub-arraying will deliver tighter NS mass, MoI, spin, glitch and precession constraints that, with X-ray and GW data, probe cold ultra-dense matter.

  6. Understanding Pulsar Wind Nebulae with the SKA

    astro-ph.HE 2026-06 unverdicted novelty 2.0

    SKA will enable spatially resolved radio studies of pulsar wind nebulae to probe particle acceleration and propagation in ultra-relativistic outflows.
