We report simultaneous observations in the X-ray, infrared, and radio wavelengths of the galactic superluminal source GRS 1915+105. During episodes of rapid disappearance and follow up replenishment of the inner accretion disk evidenced by the X-ray oscillating flux, we observe the ejection of relativistic plasma clouds in the form of synchrotron flares at infrared and radio wavelengths. The expelled clouds contain very energetic particles with Lorentz factors of about 1000, or more. These ejections can be viewed as small-scale analogs of the more massive ejecta with relativistic bulk motions that have been previously observed in GRS 1915+105.

  1. Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105

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

    VLBI observations during 2025 radio flares find no detectable jet motion in GRS 1915+105, implying its obscured-state jets are slower (βΓ≲0.40) than the pre-2019 relativistic jets.

  2. Revisiting Disc-Jet Coupling in Black Hole X-ray Binaries: On the Nature of Disc Dynamics and Jet Velocity

    astro-ph.HE 2025-07 conditional novelty 5.0 of 10

    Across thirteen black hole X-ray binaries, type-A QPOs show negative lags and often precede radio flares, type-B QPOs accompany the flares, and inferred soft-intermediate-state jet velocities are moderately relativistic.

  3. A 0.03 Hz Radio Quasi-periodic Oscillation During the 2025 Flare of GRS 1915+105

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

    A recurring 0.03 Hz radio QPO was detected in the 2025 flare of GRS 1915+105 at >5.9 sigma in one epoch, identical across S- and X-bands and prior years, indicating an intrinsic accretion-jet timescale.
