  • SDSS-IV MaNGA: How Galaxy I... SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei
    Steffen, Joshua L.; Fu, Hai; Brownstein, Joel R. ... The Astrophysical journal, 01/2023, Letnik: 942, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey. We ...

  • SDSS-IV MaNGA: Galaxy Pair ... SDSS-IV MaNGA: Galaxy Pair Fraction and Correlated Active Galactic Nuclei
    Fu, Hai; Steffen, Joshua L.; Gross, Arran C. ... The Astrophysical journal, 04/2018, Letnik: 856, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    We have identified 105 galaxy pairs at z ∼ 0.04 with the MaNGA integral-field spectroscopic data. The pairs have projected separations between 1 and 30 kpc, and are selected to have radial velocity ...

  • Testing the Radio-selection... Testing the Radio-selection Method of Dual Active Galactic Nuclei in the Stripe 82 Field
    Gross, Arran C.; Fu, Hai; Myers, A. D. ... The Astrophysical journal, 03/2023, Letnik: 945, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract We test the merger-induced dual active galactic nuclei (dAGNs) paradigm using a sample of 35 radio galaxy pairs from the Sloan Digital Sky Survey Stripe 82 field. Using Keck optical ...

  • SDSS-IV MaNGA: The Radial P... SDSS-IV MaNGA: The Radial Profile of Enhanced Star Formation in Close Galaxy Pairs
    Steffen, Joshua L.; Fu, Hai; Comerford, J. M. ... The Astrophysical journal, 03/2021, Letnik: 909, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract We compare the radial profiles of the specific star formation rate (sSFR) in a sample of 169 star-forming galaxies in close pairs with those of mass-matched control galaxies in the SDSS-IV ...

  • Evidence for Merger-Induced... Evidence for Merger-Induced AGN Fueling Using Integral Field Spectroscopy
    Steffen, Joshua L 01/2022
    Dissertation

    Hydrodynamical simulations of galaxy mergers have suggested that merger-induced gas-inflows may be able to fuel the central supermassive black hole (SMBH), triggering an active galactic nucleus ...

  • The Spatial Profile of Tida... The Spatial Profile of Tidally Induced Star Formation
    Steffen, Joshua L 01/2020
    Dissertation

    We use the MaNGA integral field spectroscopic (IFS) survey to study star formation in interacting galaxies. We identify a set of galaxy pairs both inside and outside of the MaNGA survey's field of ...
