Testing the Blazar Sequence: Synchrotron Peak Frequency Against Bolometric Luminosity in a Representative Sample

This paper addresses a single accounting question in the physics of relativistic jets: whether more luminous blazars really peak at lower synchrotron frequencies, as the blazar sequence proposes, when the trend is fitted to a representative set of published spectral energy distributions. Using synchrotron peak frequencies and bolometric luminosities for eight representative blazars spanning the full peak range, the calculation derives new bounds and budgets from standard synchrotron and special-relativistic relations, with every number produced by the deposited compute script. The headline results are: loglog slope = -0.994, spearman rho = -1, n = 8. The fitted trend is negative, with a slope near minus one in the logarithmic plane and a perfect negative rank ordering in this representative set: as bolometric luminosity rises by four orders of magnitude, the synchrotron peak falls by about four. The study is a computation from stated assumptions and published inputs; it is simulated, not measured, and its conclusions are stated at the precision those inputs support.
