Figure caption: Left: posteriors of Fourier component variance Φ i  for the CURN free (left) and HD free (right) models (see Section 2), plotted at their corresponding frequencies f  i  = i/T, with T the 16.03 yr extent of the data set. Excess power is observed in bins 1–8 (somewhat marginally in bin 6); Hellings–Downs-correlated power in bins 1–5 and 8. The dashed line plots the best-fit power law, which has γ ≃ 3.2 (as in Figure 1(d)); the fit is pushed to lower γ by bins 1 and 8. The dotted line plots the best-fit power law when γ is fixed to 13/3; it overshoots in bin 1 and undershoots in bin 8. Right: posteriors of variance Φ2 in Fourier bin 2 (f 2 = 3.95 nHz) in a CURN free + HD free + MONOPOLE free + DIPOLE free model, showing evidence of a quasi-monochromatic monopole process (dashed). No monopole or dipole power is observed in all other bins of that joint model, with ΦCURN,i  and ΦHD,i  posteriors consistent with the left panel.

Figure caption: Support for CURN  γ  (blue) and HD  γ  correlations (orange) in each pulsar, as measured by a dropout analysis. Dropout factors greater than 1 indicate support for the CURN  γ  or HD  γ , while those less than 1 show that the pulsar disfavors it. We find significant spread in the dropout factors among pulsars with long observation times, but overall more pulsars favor CURN  γ  participation and HD  γ  correlations than disfavor them.

Figure caption: Posteriors of HD  γ  amplitude (for f ref = 1 yr−1) and spectral slope for the 15 yr data set (blue), compared to power-law fits to simulated GWB spectra (red dashed) from a population of SMBHBs generated by HOLODECK (L. Z. Kelley et al. 2023, in preparation) under the assumption of purely GW-driven binary evolution and narrowly distributed model parameters based on galaxy merger observations. We show 1σ/2σ/3σ regions, and the dashed line indicates γ = 13/3. The broad contours confirm that population variance can lead to a significant spread of spectral characteristics.

Figure caption: Power-law (CURN  γ ; blue) and t-process power-law (CURN TPS; orange) spectral posteriors. Left: reconstructed spectra, compared to free-spectral bin-variance posteriors (CURN TPS; violin plots). Right: joint ﹩({\mathrm{log}}_{10}A,\gamma )﹩ posteriors. The “fuzzy” t-process allows local deviations from a perfect power law, producing wider constraints that are more consistent with γ = 13/3 (dashed line).

Figure caption: S/N growth as a function of time and number of pulsars. As we move from left to right we add an additional 6 months of data at each step. New pulsars are added when they accumulate 3 yr of data. The blue violin plot shows the distribution of the optimal statistic S/N over CURN  γ  noise parameters. The dashed orange line shows the number of pulsars used for each time slice.

Figure caption:  CURN  γ  posterior distributions using DMGP (red) and DMX (blue) to model DM variations. The dashed line marks γ CURN = 13/3. While the posteriors are broadly consistent, DMGP shifts the γ CURN posterior to higher values, making it more consistent with γ CURN = 13/3.

Figure caption: Top: sky locations of the 67 pulsars used in the 15 yr GWB analysis. Markers indicate which telescopes observed the pulsar. Bottom: distribution of angular separations probed by the pulsars in the full data set (orange), the Arecibo data set (blue), and the GBT data set (red). Because Arecibo and GBT mostly observed pulsars at different declinations, there are few intertelescope pairs at small angular separations, resulting in a deficit of pairs for the full data set in the first bin.
