Constraining the synchrotron peak and estimating the VHE brightness of a sample of extreme high synchrotron peak blazars

Federica Sibani, Stefano Marchesi, Ettore Bronzini +5

We present the results of a multi-wavelength study of a population of X-ray bright ($\log ({\mathrm{F}}_{0.2-12\mathrm{keV}})>-12.5$), non-$\gamma$-ray detected high and extreme high synchrotron peak…
