The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
The X-rayUV Luminosity Relation of eROSITA Quasars
Andrea Sacchi, Guido Risaliti, Matilde Signorini +3
The non-linear relation between the UV and X-ray luminosity in quasars has been studied for decades. However, as we lack a comprehensive model able to explain it, its investigation…
X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA
Andrea Sacchi, Akos Bogdan, Urmila Chadayammuri +1
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass gal…
The power of the rings: the GRB 221009A soft X-ray emission from its dust-scattering halo
Andrea Tiengo, Fabio Pintore, Beatrice Vaia +11
GRB 221009A is the brightest gamma-ray burst (GRB) ever detected and occurred at low Galactic latitude. Owing to this exceptional combination, its prompt X-ray emission could be de…
Supersoft, luminous X-ray sources in galactic nuclei
Andrea Sacchi, Guido Risaliti, Giovanni Miniutti
Tidal disruption events (TDEs) are usually discovered at X-ray or optical wavelengths through their transient nature. A characteristic spectral feature of X-ray detected TDEs is a…
What causes the fragmentation of debris streams in TDEs?
Andrea Sacchi, Giuseppe Lodato, Claudia Toci +1
A tidal disruption event (TDE) occurs when a star passes too close to a supermassive black hole and gets torn apart by its gravitational tidal field. After the disruption, the stel…
"Failed" tidal disruption events and X-ray flares from the Galactic Center
Andrea Sacchi, Giuseppe Lodato
The process of tidal disruption of stars by a supermassive black hole (SMBH) provides luminous UV and soft X-ray flares with peak luminosities of ergs/sec and dur…
