We report new radio imaging of the large scale radio structure of M87 with the VLA at 90 cm. These new images show the complex structure of the radio emission more clearly than previous attempts, some of which date back to the 1940's. The images suggest that the outward flow from the M87 nucleus extends well beyond the 2 kpc jet. Two ``bubbles'' of synchrotron emission appear to be inflated by this flow. A simple model of the emission, combined with our knowledge of the inner jet, suggests that the energy input into this region from the M87 nucleus exceeds the energy being radiated away as X-rays. This argues that the region within 40 kpc of the center of M87 is currently dominated by energy input from the M87 nucleus. The gas in the region is expanding, not flowing inward as is envisioned in the cooling flow model.

  1. Numerical Simulations of Restarted Jets -- I. Dynamics

    astro-ph.HE 2026-07 accept novelty 6.5 of 10

    Restarted jets propagate ballistically through rarefied remnant cocoons with minimal backflow, decelerating only at dense entrained structures, after the cocoon evolves through conical-cylindrical-mushroom phases shap...

  2. Fermi-Large Area Telescope Detection of Very High Energy (>100 GeV) Emission from Compton-Dominated Blazars

    astro-ph.HE 2026-07 accept novelty 6.0 of 10

    Systematic Fermi-LAT search detects VHE emission from 14 Compton-dominated blazars (4 new at >5σ) and constrains the emitting region to >1.1–1.4 BLR radii.

  3. Constraining the jet base emission of M87* with past and future Event Horizon Telescope observations

    astro-ph.HE 2026-06 unverdicted novelty 4.0 of 10

    Synthetic EHT data from semi-analytic jet models show that the 2022 array configuration enables robust recovery of faint horizon-scale jet emission in M87* when jet intensity exceeds a determined lower limit.
