Extended Data Fig. 6: Average X-ray (0.3-5 keV) power density spectrum of AT2022cmc.

The frequency resolution and the Nyquist frequency are 1/950 Hz and 1/8 Hz, respectively. This power spectrum is an average of 29 individual PDS. The dashed, red curve is the best-fit power-law model. Systematic variability on timescales of ~ 1000 s (lowest frequency bin) is evident. All the frequencies and hence the timescales are as measured in the observer frame. The error bars represent 1σ uncertainties.
