Manna, A. Pal, S. Baug, T. Detection of comet 3I/ATLAS in radio wavelength during closest approach to Earth using uGMRT

The uGMRT is the upgraded Giant Metrewave Radio Telescope, an astronomical array of “dishes” in India. “Giant” is apt, but “dishes” is in quotes because the parabolic surface is wire-mesh, which you can see through. At metrewaves, fist-sized gaps are acceptable. But is the data acceptable? The authors attempt to study our little friend in uGMRT’s feasible wavebands. As of now, they certainly claim detection of the small body (some days stronger than others). Going further into detection of gas molecules or dust particles, that’s a different story. Manna et al. leave us hanging on a final analysis, and any claims of detection or non-detection at 3I/ATLAS. We’re waiting.
