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 (), non--ray detected high and extreme high synchrotron peak…

CTAO LST-1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission

K. Abe, S. Abe, A. Abhishek +333

The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Investigating its potential tera-electronvolt counterpart could provi…

A Multi-Wavelength Characterization of the Obscuring Medium at the Center of NGC 6300

D. Sengupta, N. Torres-Albà, A. Pizzetti +9

Most of the super-massive black holes in the Universe accrete material in an obscured phase. While it is commonly accepted that the "dusty torus" is responsible for the nuclear obs…

Investigating the nuclear properties of highly accreting active galactic nuclei with XMM-Newton

M. Laurenti, F. Tombesi, F. Vagnetti +7

Our understanding of highly accreting AGNs is hampered by the lack of a complete systematic investigation in terms of their main spectral and variability properties, and by the rel…

XMM-Newton Ultra Narrow Deep Field survey II: X-ray spectral analysis of the brightest AGN population

M. Elías-Chávez, A. L. Longinotti, Y. Krongold +6

In this work, we present the results of a detailed X-ray spectral analysis of the brightest AGNs detected in the XMM-Newton 1.75 Ms Ultra Narrow Deep Field. We analyzed 23 AGNs tha…
