  • Fig. 1 Superradiance models (solid curves) for the G107.298+5.639 flaring event occurring between MJD 57,260 to 57,300 in Fig. 3 of Szymczak et al. (20) (that is, day 7260 to 7300 in our figure) for the vlsr = −8.57 km s−1 6.7-GHz methanol (red dots) and vlsr = −7.86 km s−1 22-GHz water (blue dots) spectral features.

    These flares were repeated on an approximately 34.4-day period (20). The methanol and water data/models use the vertical axes on the left-hand and right-hand sides, respectively. For methanol, the model parameters are Embedded Image, Embedded Image, and Embedded Image, yielding a mean inverted column density of Embedded Image, whereas for water, the parameters are Embedded Image, Embedded Image, Embedded Image, and Embedded Image. Both superradiance models were initiated at the same time, on day 7261.5. Data is taken from Szymczak et al. 2016 (20). See Supplementary Materials for data.
