We present the result of multi-wavelength observations of the microquasar GRS 1915+105 in a plateau state with a luminosity of ~7.5x10^{38) erg s-1 (~40% L_Edd), conducted simultaneously with the INTEGRAL and RXTE satellites, the ESO/NTT, the Ryle Telescope, the NRAO VLA and VLBA, in 2003 April 2-3. For the first time were observed concurrently in GRS 1915+105 all of the following properties: a strong steady optically thick radio emission corresponding to a powerful compact jet resolved with the VLBA, bright near-IR emission, a strong QPO at 2.5 Hz in the X-rays and a power law dominated spectrum without any cutoff in the 3-400 keV range.

Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105
astro-ph.HE 2026-07 conditional novelty 6.0

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.
