Theoretical evolution of optical strong lines across cosmic time
Lisa J. Kewley,Lisa J. Kewley,Michael A. Dopita,Michael A. Dopita,Claus Leitherer,Romeel Davé,Tiantian Yuan,Mark Allen,Brent Groves,Ralph S. Sutherland +9 more
TL;DR: In this article, the authors use the optical diagnostic Baldwin-Phillips-Terlevich (BPT) diagram as a tool for investigating the spectral properties of ensembles of active galaxies.

The cosmic bpt diagram: confronting theory with observations
Lisa J. Kewley,Lisa J. Kewley,Christian Maier,Kiyoto Yabe,Kouji Ohta,Masayuki Akiyama,Michael A. Dopita,Michael A. Dopita,Tiantian Yuan +8 more
TL;DR: In this article, the authors compare a large sample of galaxies between 0.8 < z < 1.5 and z ≥ 2.5, and derive a new redshift-dependent classification line that utilizes the standard optical diagnostic line ratios [O III] /Hβ and [N II]/Hα.
Journal ArticleDOI
The role of starburst-active galactic nucleus composites in luminous infrared galaxy mergers: insights from the new optical classification scheme
TL;DR: The authors investigated the fraction of starbursts, active galactic nucleus (AGN) composites, Seyferts, and low-ionization narrow emission-line region galaxies (LINERs) as a function of infrared luminosity (L IR) and merger progress for ~500 infrared-selected galaxies.

The Role of Starburst-AGN composites in Luminous Infrared Galaxy Mergers: Insights from the New Optical Classification Scheme
TL;DR: In this article, the authors investigate the fraction of starbursts, starburst-AGN composites, Seyferts, and LINERs as a function of infrared luminosity (L_IR) and merger progress for ~500 infrared-selected galaxies.

TL;DR: Spectroscopic confirmation of a massive, quiescent galaxy at redshift z = 3.717 demonstrates that the galaxy must have formed the majority of its stars quickly, within the first billion years of cosmic history in a short, extreme starburst.
