“…Furthermore, the details of exactly how, or indeed if, these AGNs impact upon the evolution of their host galaxies remain controversial and uncertain (e.g. Husemann et al 2016;Villar-Martín et al 2016;Maiolino et al 2017;Harrison 2017;Cresci & Maiolino 2018;Perna et al 2018;Rosario et al 2018;Baron et al 2018;Scholtz et al 2018Scholtz et al , 2020do Nascimento et al 2019;Brownson et al 2020;Yesuf & Ho 2020;Greene et al 2020;Bluck et al 2020;Bischetti et al 2020). Building a multiwavelength quasar survey to address these questions is the focus of the Quasar Feedback Survey, which we introduce here.…”

We present the first results from the Quasar Feedback Survey, a sample of 42 z < 0.2, [O iii] luminous AGN (L[O III] > 1042.1 ergs s−1) with moderate radio luminosities (i.e. L1.4GHz > 1023.4 W Hz−1; median L1.4GHz = 5.9 × 1023 W Hz−1). Using high spatial resolution (∼0.3–1 arcsec), 1.5–6 GHz radio images from the Very Large Array, we find that 67 percent of the sample have spatially extended radio features, on ∼1–60 kpc scales. The radio sizes and morphologies suggest that these may be lower radio luminosity versions of compact, radio-loud AGN. By combining the radio-to-infrared excess parameter, spectral index, radio morphology and brightness temperature, we find radio emission in at least 57 percent of the sample that is associated with AGN-related processes (e.g. jets, quasar-driven winds or coronal emission). This is despite only 9.5–21 percent being classified as radio-loud using traditional criteria. The origin of the radio emission in the remainder of the sample is unclear. We find that both the established anti-correlation between radio size and the width of the [O iii] line, and the known trend for the most [O iii] luminous AGN to be associated with spatially-extended radio emission, also hold for our sample of moderate radio luminosity quasars. These observations add to the growing evidence of a connection between the radio emission and ionised gas in quasar host galaxies. This work lays the foundation for deeper investigations into the drivers and impact of feedback in this unique sample.

“…The majority of these 111 galaxies were selected as BOSS ancillary targets because their ugriz or WISE colors resembled those of high-redshift quasars or LRGs. Several others were selected because they had matches in the Chandra Source Catalog (Evans et al 2010) or the FIRST radio survey (Becker et al 1995, see also Greene et al 2020). Galaxies with non-CMASS target flags tend to be slightly brighter and lie at lower redshifts than the median of the full SQuIGG LE sample.…”

“…We fit for stellar mass and metallicity using the massmetallicity prior described in Leja et al (2019b). We also fit for the velocity dispersion of the SDSS spectra, using a gaussian prior with the mean and sigma of the output pPXF (Cappellari 2017) velocity dispersion fits (see Greene et al 2020). We assume the Kriek & Conroy (2013) dust law, with a free A v and dust index; in this dust law, the bump strength is tied to the slope.…”

We describe the SQuIGG LE survey of intermediate-redshift post-starburst galaxies. We leverage the large sky coverage of the SDSS to select ∼1300 recently-quenched galaxies at 0.5 < z ≤ 0.9 based on their unique spectral shapes. These bright, intermediate-redshift galaxies are ideal laboratories to study the physics responsible for the rapid quenching of star formation: they are distant enough to be useful analogs for high-redshift quenching galaxies, but low enough redshift that multi-wavelength follow-up observations are feasible with modest telescope investments. We use the Prospector code to infer the stellar population properties and non-parametric star formation histories of all galaxies in the sample. We find that SQuIGG LE galaxies are both very massive (M * ∼ 10 11.25 M ) and quenched, with inferred star formation rates 1M yr −1 , more than an order of magnitude below the star-forming main sequence. The best-fit star formation histories confirm that these galaxies recently quenched a major burst of star formation: > 75% of SQuIGG LE galaxies formed at least a quarter of their total stellar mass in the recent burst, which ended just ∼ 200 Myr before observation. We find that SQuIGG LE galaxies are on average younger and more burst-dominated than most other z 1 poststarburst galaxy samples. This large sample of bright post-starburst galaxies at intermediate redshift opens a wide range of studies into the quenching process. In particular, the full SQuIGG LE survey will investigate the molecular gas reservoirs, morphologies, kinematics, resolved stellar populations, AGN incidence, and infrared properties of this unique sample of galaxies in order to place definitive constraints on the quenching process.

“…Tracing the features of active galactic nuclei (AGN) activity across cosmic time has highlighted more evidence of co-evolution. For example, total AGN accretion rate density is highly correlated with changes in star-formation rate (SFR) density (Madau & Dickinson 2014;Delvecchio et al 2014;Aird et al 2015); the effect of AGN on their host galaxies in the form of feedback is associated with the quenching of star formation (Di Matteo et al 2005;Fabian 2012;Greene et al 2020); and feedback could also explain the observed bi-modality in colour-magnitude and colour-mass space (Baldry et al 2004; ★ E-mail: klb69@leicester.ac.uk Martin et al 2007;Schawinski et al 2014).…”

We present the identification and analysis of an unbiased sample of AGN that lie within the local galaxy population. Using the MPA-JHU catalogue (based on SDSS DR8) and 3XMM DR7 we define a parent sample of 25,949 local galaxies (𝑧 ≤ 0.33). After confirming that there was strictly no AGN light contaminating stellar mass and star-formation rate calculations, we identified 917 galaxies with central, excess X-ray emission likely originating from an AGN. We analysed their optical emission lines using the BPT diagnostic and confirmed that such techniques are more effective at reliably identifying sources as AGN in higher mass galaxies: rising from 30% agreement in the lowest mass bin to 93% in the highest. We then calculated the growth rates of the black holes powering these AGN in terms of their specific accretion rates (∝ 𝐿 𝑋 /𝑀 * ). Our sample exhibits a wide range of accretion rates, with the majority accreting at rates ≤ 0.5% of their Eddington luminosity. Finally, we used our sample to calculate the incidence of AGN as a function of stellar mass and redshift. After correcting for the varying sensitivity of 3XMM, we split the galaxy sample by stellar mass and redshift and investigated the AGN fraction as a function of X-ray luminosity and specific black hole accretion rate. From this we found the fraction of galaxies hosting AGN above a fixed specific accretion rate limit of 10 −3.5 is constant (at ≈ 1%) over stellar masses of 8 < log M * /M < 12 and increases (from ≈ 1% to 10%) with redshift.
