A simple toy model for the electromagnetic variability of lump-dominated circumbinary disks around binary black holes
R. Mignon-Risse, P. Varniere, F. Casse
The electromagnetic detection of circumbinary disks around pre-merger binary black holes (BBHs) relies on theoretical predictions. These are generally obtained through expensive nu…
Direct observation of the X-ray counterpart of the Hα filaments and of the sloshing spiral in the Perseus galaxy cluster
