    Rosat observations of hyperluminous IRAS galaxies: Upper limits and their implications by Wilman, R

    Published 1999
    “…We discuss the implications, for the properties of hidden active nuclei and starbursts, of the non-detection of four hyperluminous IRAS galaxies with long, pointed ROSAT HRI observations.The results of a search of the ROSAT archive for serendipitous observations of ULIRGs in the catalogue of Clements et al. (1996,1998) are also presented. …”

    X-ray QSO evolution from a very deep ROSAT survey by Jones, L, McHardy, I, Merrifield, MR, Mason, K, Smith, P, Abraham, R, Branduardi-Raymont, G, Newsam, A, Dalton, G, Rowan-Robinson, M, Luppino, G

    Published 1996
    “…The survey, performed with the ROSAT PSPC, has 89% spectroscopic completeness. The QSO log(N)-log(S) relation is found to have a break to a flat slope at faint fluxes. …”

    Chandra Evidence of a Flattened, Triaxial Dark Matter Halo in the Elliptical Galaxy NGC 720 by Jeltema, Tesla E., Canizares, Claude R., Garmire, Gordon P., Buote, David A.

    Published 2013
    “…The Chandra data confirm the magnitude of the ~20° position angle (P.A.) twist discovered by ROSAT over this region. However, the twist in the Chandra data is more gradual and occurs at smaller a, also because of the point sources contaminating the ROSAT values. …”

    The Clusters Hiding in Plain Sight (CHiPS) Survey: A First Discovery of a Massive Nearby Cluster around PKS 1353−341 by Somboonpanyakul, Taweewat, McDonald, Michael, Lin, Henry W, Stalder, Brian, Stark, Antony

    Published 2021
    “…We introduce the first result of the Clusters Hiding in Plain Sight (CHiPS) survey, which aims to discover new nearby massive galaxy clusters that were incorrectly identified as isolated point sources in the ROSAT All-sky Survey. We present a Chandra X-ray observation of our first newly discovered low-redshift (z = 0.223) galaxy cluster with a central X-ray bright point source, PKS 1353-341. …”
