Spectroscopy from Photometry: A Population of Extreme Emission Line Galaxies at 1.7 ≲ z ≲ 6.7 Selected with JWST Medium Band Filters [PDF]

Astrophysical Journal Letters, 2023
We use JWST/NIRCam medium band photometry in a single pointing of the Canadian NIRISS Unbiased Cluster Survey to identify 118 extreme emission-line galaxies (EELGs) over 1.7 ≲ z ≲ 6.7, selected using a set of color cuts that target galaxies with extreme [

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

Monthly Notices of the Royal Astronomical Society, 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 $z \sim 1$.

KILOPARSEC-SCALE PROPERTIES OF EMISSION-LINE GALAXIES [PDF]

, 2014
We perform a detailed study of the resolved properties of emission-line galaxies at kiloparsec scales to investigate how small-scale and global properties of galaxies are related. We use a sample of 119 galaxies in the GOODS fields.

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 ...
