    • Bipolar ionization cones in the extended narrow-line region of nearby QSO2s 

      Storchi-Bergmann, Thaisa; Oliveira, Bruno Dall'Agnol de; Micchi, L. F. Longo; Schmitt, Henrique Roberto; Fischer, Travis C.; Kraemer, S. B.; Crenshaw, Daniel Michael; Maksym, W. Peter; Elvis, Martin; Fabbiano, Giuseppina; Colina, Luis (2018) [Journal article]
      We have used narrowband [O III] λλ4959, 5007 and Hα+[N II] λλ6548, 84 Hubble Space Telescope (HST) images of nine luminous (L[O III]>1042 erg s−1) type 2 QSOs with redshifts 0.1<z<0.5 in order to constrain the geometry of ...
    • CHEERS results from NGC 3393 : III. Chandra x-ray spectroscopy of the narrow line region 

      Maksym, W. Peter; Fabbiano, Giuseppina; Elvis, Martin; Karovska, Margarita; Paggi, Alessandro; Raymond, John Charles; Wang, Junfeng; Storchi-Bergmann, Thaisa; Risaliti, Guido (2019) [Journal article]
      We present spatially resolved Chandra narrow-band imaging and imaging spectroscopy of NGC 3393. This galaxy hosts a Compton-thick Seyfert 2 active galactic nucleus (AGN) with sub-kpc bipolar outflows that are strongly ...
    • CHEERS results from NGC 3393 : II. Investigating the extended narrow-line region using deep Chandra observations and Hubble Space Telescope narrow-line imaging 

      Maksym, W. Peter; Fabbiano, Giuseppina; Elvis, Martin; Karovska, Margarita; Paggi, Alessandro; Raymond, John Charles; Wang, Junfeng; Storchi-Bergmann, Thaisa (2017) [Journal article]
      The CHandra Extended Emission Line Region Survey (CHEERS) is an X-ray study of nearby active galactic nuclei (AGNs) designed to take full advantage of Chandraʼs unique angular resolution by spatially resolving feedback ...
    • Mapping Seyfert and LINER excitation modes in the inner kpc of NGC 3393 

      Maksym, W. Peter; Fabbiano, Giuseppina; Elvis, Martin; Karovska, Margarita; Paggi, Alessandro; Raymond, John Charles; Wang, Junfeng; Storchi-Bergmann, Thaisa (2016) [Journal article]
      We mapped the extended narrowline region (ENLR) of NGC 3393 on scales of r  4 (~1 kpc) from the nucleus using emission line images of Hα λ6563, [O III]l5007, and [S II]ll6717, 6731, taken with the Hubble Space Telescope ...
    • Quantifying feedback from narrow line region outflows in nearby active galaxies II. Spatially resolved mass outflow rates for the QSO2 Markarian 34 

      Revalski, Mitchell; Dashtamirova, D.; Crenshaw, Daniel Michael; Kraemer, S. B.; Fischer, Travis C.; Schmitt, Henrique Roberto; Gnilka, C. L.; Schmidt, Jana G.; Elvis, Martin; Fabbiano, Giuseppina; Storchi-Bergmann, Thaisa; Maksym, W. Peter; Gandhi, Poshak (2018) [Journal article]
      We present spatially resolved mass outflow rate measurements (M˙ out) for the narrow line region of Markarian 34, the nearest Compton-thick type 2 quasar (QSO2). Spectra obtained with the Hubble Space Telescope and at ...
