Title:On the hypothesis of an advection-dominated flow in the core of NGC 1052: new constraints from a BeppoSAX observation
View PDFAbstract: We report the results of a broadband (0.1-100 keV) X-ray observation of the nearby elliptical galaxy NGC1052, performed with the BeppoSAX observatory. We confirm the presence of a bright (2-10 keV luminosity ~ 4 x 10^{42} erg/s) and strongly absorbed (NH ~ 2 x 10^{23} atoms/cm/cm) X-ray source. The flatness of the X-ray spectrum (photon index ~1.4), the estimated low accretion rate (m-dot \~ 10^{-4}) and the radio-to-X-ray spectral energy distribution suggest that this observation may represent the first direct measurement above 10 keV of an accretion-dominated flow in an elliptical galaxy.

arXivLabs: experimental projects with community collaborators
arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.
Both individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them.
