    The nature of the ultraluminous X-ray sources inside galaxies and their relation to local QSOs

    Get PDF
    It is suggested that many of the ultraluminous compact x-ray sources now being found in the main bodies of galaxies, particularly those that are active, like M82, NGC 3628 and others, are "local" QSOs, or BL Lac objects, with high intrinsic redshifts in the process of being ejected from those galaxies. Evidence in support of this hypothesis is summarized.Comment: submitted to A&A Letter

    The Discovery of a High Redshift X-ray Emitting QSO Very Close to the Nucleus of NGC 7319

    A strong X-ray source only 8" from the nucleus of the Sy2 galaxy NGC 7319 in Stephan's Quintet has been discovered by Chandra. We have identified the optical counterpart and show it is a QSO with ze=2.114z_e = 2.114. It is also a ULX with Lx=1.5x1040ergsec−1L_x = 1.5 x 10^{40} erg sec^{-1}. From the optical spectra of the QSO and interstellar gas in the galaxy (z = .022) we show that it is very likely that the QSO and the gas are interacting.Comment: 8 figures, 5 color, minimized ps siz
