You can't see me: Super-Eddington growth hindering X-ray detection in high-z broad-line active galactic nuclei
Alessandro Trinca, Alessandro Lupi, Francesco Haardt +1
We revisit black hole mass estimates for high-redshift broad-line active galactic nuclei (AGNs) discovered with JWST by jointly analysing their broad emission lines and their syste…
X-ray investigation of possible super-Eddington accretion in a radio-loud quasar at
L. Ighina, A. Caccianiga, T. Connor +19
We present radio and X-ray observations of the recently discovered radio-powerful quasar RACS J032021.44352104.1 using uGMRT, ATCA, LBA, and Chandra. The observed radio…
Cyclostationary signals in LISA: a practical application to Milky Way satellites
Federico Pozzoli, Riccardo Buscicchio, Antoine Klein +3
One of the primary sources of gravitational waves (GWs) anticipated to be detected by the Laser Interferometer Space Antenna (LISA) are Galactic double white dwarf binaries (DWDs).…
25 years of XMM-Newton observations of the Sgr A complex: 3D distribution and internal structure of the clouds
G. Stel, G. Ponti, F. Haardt +1
Sgr A* is currently very faint. However, X-ray radiation reflected by the Sgr A complex, a group of nearby molecular clouds, suggests that it went through one or more periods of hi…
