Characterizing Extreme Emission Line Galaxies. II. A Self-consistent Model of Their Ionizing Spectrum [PDF]

Astrophysical Journal, 2021
Observations of high-redshift galaxies (z > 5) have shown that these galaxies have extreme emission lines with equivalent widths much larger than their local star-forming counterparts.

The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: exploring the halo occupation distribution model for emission line galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2020
We study the modelling of the halo occupation distribution (HOD) for the eBOSS DR16 emission line galaxies (ELGs). Motivated by previous theoretical and observational studies, we consider different physical effects that can change how ELGs populate ...

The galaxy–halo connection of emission-line galaxies in IllustrisTNG [PDF]

, 2020
We employ the hydrodynamical simulation IllustrisTNG-300-1 to explore the halo occupation distribution (HOD) and environmental dependence of luminous star-forming emission-line galaxies (ELGs) at $z \sim 1$.

Do model emission line galaxies live in filaments at z ∼ 1? [PDF]

, 2020
Current and future cosmological surveys are targeting star-forming galaxies at $z\sim 1$ with nebular emission lines. We use a state-of-the-art semi-analytical model of galaxy formation and evolution to explore the large scale environment of star-forming

OMEGA: OSIRIS Mapping of Emission-Line Galaxies in A901/2 [PDF]

Proceedings of the International Astronomical Union, 2014
This work presents the first results from an ESO Large Programme carried out using the OSIRIS instrument on the 10m GTC telescope (La Palma). We have observed a large sample of galaxies in the region of the Abell 901/902 system (z∼0.165) which has been ...

The chemical composition of metal-poor emission-line galaxies in the Data Release 3 of the Sloan Digital Sky Survey [PDF]

, 2006
We have re-evaluated empirical expressions for the abundance determination of N, O, Ne, S, Cl, Ar and Fe taking into account the latest atomic data and constructing an appropriate grid of photoionization models with state-of-the art model atmospheres ...

The Circumgalactic Medium of eBOSS Emission Line Galaxies: Signatures of Galactic Outflows in Gas Distribution and Kinematics [PDF]

Astrophysical Journal, 2018
We study the distribution and kinematics of the cool circumgalactic medium (CGM) of emission line galaxies (ELGs) traced by metal absorption lines. Using about 200,000 ELGs from SDSS-IV eBOSS and half a million background quasars from SDSS, we measure ...

Extreme emission line galaxies detected in JADES JWST/NIRSpec I: inferred galaxy properties [PDF]

Monthly notices of the Royal Astronomical Society
Extreme emission line galaxies (EELGs) exhibit large equivalent widths (EW) in their rest-optical emission lines ([OIII]λ5007 or Hα rest-frame EW>750Å) which can be tied to a recent upturn in star formation rate (SFR), due to the sensitivity of the ...

Machine-learning Classifiers for Intermediate Redshift Emission-line Galaxies [PDF]

Astrophysical Journal, 2019
Classification of intermediate redshift (z = 0.3–0.8) emission line galaxies as star-forming galaxies, composite galaxies, active galactic nuclei (AGNs), or low-ionization nuclear emission regions (LINERs) using optical spectra alone was impossible ...
