>we carried out deep mapping observations of the 21 cm H i emission over a region of around 30′ × 30′ centred on SQ. ... Here we report atomic hydrogen (H i) observations in the vicinity of SQ with a smoothed sensitivity of 1σ = 4.2 × 1016 cm−2 per channel.

I searched the original paper and they don't have any discussion regarding molecular hydrogen. It is also extremely hard to directly detect molecular hydrogen as far as I know.
