  • Observational Evidence for ... Observational Evidence for Cosmological Coupling of Black Holes and its Implications for an Astrophysical Source of Dark Energy
    Farrah, Duncan; Croker, Kevin S.; Zevin, Michael ... Astrophysical journal. Letters, 02/2023, Volume: 944, Issue: 2
    Journal Article
    Peer reviewed
    Open access

    Abstract Observations have found black holes spanning 10 orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is, however, provisional as its behavior at infinity ...

  • A Preferential Growth Chann... A Preferential Growth Channel for Supermassive Black Holes in Elliptical Galaxies at z ≲ 2
    Farrah, Duncan; Petty, Sara; Croker, Kevin S. ... Astrophysical journal/˜The œAstrophysical journal, 02/2023, Volume: 943, Issue: 2
    Journal Article
    Peer reviewed
    Open access

    Abstract The assembly of stellar and supermassive black hole (SMBH) mass in elliptical galaxies since z ∼ 1 can help to diagnose the origins of locally observed correlations between SMBH mass and ...

  • Stellar and black hole asse... Stellar and black hole assembly in z < 0.3 infrared-luminous mergers: intermittent starbursts versus super-Eddington accretion
    Farrah, Duncan; Efstathiou, Andreas; Afonso, Jose ... Monthly notices of the Royal Astronomical Society, 05/2022, Volume: 513, Issue: 4
    Journal Article
    Peer reviewed
    Open access

    ABSTRACT We study stellar and black hole mass assembly in a sample of 42 infrared-luminous galaxy mergers at z < 0.3 by combining results from radiative transfer modelling with archival measures of ...

  • Star formation rates in lum... Star formation rates in luminous quasars at 2 < z < 3
    Harris, Kathryn; Farrah, Duncan; Schulz, Bernhard ... Monthly Notices of the Royal Astronomical Society, 04/2016, Volume: 457, Issue: 4
    Journal Article
    Peer reviewed
    Open access

    We investigate the relation between star formation rates ( $\dot{{M}}_s$ ) and AGN properties in optically selected type 1 quasars at 2 < z < 3 using data from Herschel and the SDSS. We find that ...

  • The mid-infrared and CO gas... The mid-infrared and CO gas properties of an extreme star-forming FeLoBAL quasar
    Pitchford, Lura K; Farrah, Duncan; Alatalo, Katherine ... Monthly Notices of the Royal Astronomical Society, 08/2019, Volume: 487, Issue: 3
    Journal Article
    Peer reviewed
    Open access

    ABSTRACT We present a detailed study of a high-redshift iron low-ionization broad absorption line (FeLoBAL) quasar (SDSS1214 at $z$ = 1.046), including new interferometric 12CO J = 2–1 observations, ...

    Runburg, Jack; Farrah, Duncan; Sajina, Anna ... Astrophysical journal/˜The œAstrophysical journal, 01/2022, Volume: 924, Issue: 2
    Journal Article
    Peer reviewed
    Open access

    Abstract The luminosity function of active galactic nuclei (AGN) probes the history of supermassive black hole assembly and growth across cosmic time. To mitigate selection biases, we present a ...

  • Molecular Gas Heating, Star... Molecular Gas Heating, Star Formation Rate Relations, and AGN Feedback in Infrared-Luminous Galaxy Mergers
    Farrah, Duncan; Efstathiou, Andreas; Afonso, Jose ... Universe, 01/2023, Volume: 9, Issue: 1
    Journal Article
    Peer reviewed
    Open access

    We examine the origin of molecular gas heating in a sample of 42 infrared-luminous galaxies at z<0.3 by combining two sets of archival data: first, integrated CO line luminosities in the 1–0 and 5–4 ...
