BlackHoleWeather -- Jet-regulated chaotic cold accretion across the meso scale: Variability and kinematics
Vieri Cammelli, Massimo Gaspari, Filippo Barbani +10
Chaotic cold accretion (CCA) predicts that supermassive black holes are fed by multiphase clouds condensing from turbulent hot atmospheres. In jet-regulated systems cold gas must a…
The very faint X-ray transient Swift J174610-290018 at the Galactic center
Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17
Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
An acceleration-radiation model for nonthermal flares from Sgr A
Maria Petropoulou, Gabriele Ponti, Giovanni Stel +1
(Abridged) Sgr A is the electromagnetic counterpart of the accreting supermassive black hole in the Galactic center. Its emission is variable in the near-infrared (NIR) and…
The High Energy X-ray Probe (HEX-P): resolving the nature of Sgr A* flares, compact object binaries and diffuse X-ray emission in the Galactic Center and beyond
Kaya Mori, Gabriele Ponti, Matteo Bachetti +24
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ( FWHM) and broad spectral coverage (0.2-80 keV) with an effective area far sup…
Iron K-alpha echoes from the circumnuclear disk orbiting Sgr A*
G. Stel, G. Ponti, F. Haardt
Molecular clouds in the Galactic center (GC) reprocess radiation from past outbursts of nearby high-energy sources, generating a bright Fe K-alpha fluorescence at 6.4 keV. The clos…
