The nature of LINER galaxies: Ubiquitous hot old stars and rare accreting black holes (2013, background): “Since the sample selection LINERs outnumber classical Seyferts 5:1, were often counted into the AGN class (Kauffmann et al. 2003; Kauffmann & Heckman 2009; Schawinski et al. 2007), and were being impacted by the different physical apertures covered at different redshifts (Fig.”

On the sources of ionization for the gas in elliptical and lenticular galaxies (2009, background): “We measured the values for the [OIII ] equivalent width and the [OIII ]/Hβ ratio for the total emission in such apertures and compared our results with the emission-line measurements for the morphologically-selected sample of earlytype galaxies of Schawinski et al. (2007).”

Galaxy formation theory (2010, background): “Observational evidence in support of AGN feedback is beginning to emerge (Schawinski et al. 2007) and seems to favor a radio mode scenario (Schawinski 2009).”
Relativistic jet feedback in high-redshift galaxies – I. Dynamics (2016, background): “1 IN T RO D U C T I O N Feedback from active galactic nuclei (AGNs) has long been identified as playing an important role in the evolution of galaxies (e.g. Silk & Rees 1998; Di Matteo, Springel & Hernquist 2005; Bower et al. 2006; Croton et al. 2006; Schawinski et al. 2007).”
DRIVING OUTFLOWS WITH RELATIVISTIC JETS AND THE DEPENDENCE OF ACTIVE GALACTIC NUCLEUS FEEDBACK EFFICIENCY ON INTERSTELLAR MEDIUM INHOMOGENEITY (2012, background): “Several studies find statistical correlations between AGN activity, outflows, and the suppression of star formation (e.g., Schawinski et al. 2007; Farrah et al. 2012), but the connection between AGN jets and star formation remains ambiguous (Dicken et al. 2012; Hayashi et al. 2012).”
BAT AGN Spectroscopic Survey. I. Spectral Measurements, Derived Quantities, and AGN Demographics (2017, methodology): “For the [N II]λ6583 diagnostic, we further separate the star forming (HII) galaxies and composite galaxies, and separate AGN into LINERs and Seyferts (following Schawinski et al. 2007b).”
THE DEPENDENCE OF QUENCHING UPON THE INNER STRUCTURE OF GALAXIES AT 0.5 ⩽ z < 0.8 IN THE DEEP2/AEGIS SURVEY (2012, unknown): “There have been various works that support this idea (e.g., Schawinski et al. 2007; Alexander et al. 2010; Cano-Diaz et al. 2011; Farrah et al. 2011).”
The correlation of star formation quenching with internal galaxy properties and environment (2008, background): “There is also mounting observational evidence that AGN are associated with the quenching of star formation (Schawinski et al. 2006; Salim et al. 2007, hereafter S07; Schawinski et al. 2007b).”
Revisiting the Hubble sequence in the SDSS DR7 spectroscopic sample: a publicly available Bayesian automated classification (2010, result): “This result confirms that a pure color selection is not enough to select ellipticals or S0 galaxies since it is highly polluted by edge-on spirals as already shown in previous works (e.g. Schawinski et al. 2007; Lintott et al. 2008; Bernardi et al. 2010b).”
Galaxy Zoo Green Peas: discovery of a class of compact extremely star-forming galaxies (2009, methodology): “We employ a method similar to that of Schawinski et al.

Galaxy Zoo: a sample of blue early-type galaxies at low redshift (2009, methodology): “We measure the local environment using the measure of Schawinski et al. (2007a) and Yoon et al.

Active galactic nuclei flicker: an observational estimate of the duration of black hole growth phases of ∼105 yr (2015, background): “Seyfert AGN and LINERs (low ionization nuclear emission regions) beyond the extreme starburst line can further be separated (Schawinski et al. 2007; Kewley et al. 2006).”
GAMA: towards a physical understanding of galaxy formation (2009, methodology): “All spectra will be flux calibrated using in-house software and then processed by a modified version of GANDALF (Sarzi et al. 2006, Schawinski et al. 2007) to separate the continuum (with its stellar absorption lines) from the nebular emission lines.”
The Coevolution of Galaxies and Supermassive Black Holes: Insights from Surveys of the Contemporary Universe (2014, result): “These results pertain to the region within a radius of ∼ 1 to 2 kpc. Qualitatively similar results from SDSS were found by Schawinski et al. (2007) for galaxies selected morphologically to be ellipticals.”
