The optical spectra of the brightest mid-IR-selected galaxies

TL;DR

This study analyzes the optical spectra of bright mid-infrared galaxies selected by Spitzer/MIPS at 24 microns in the COSMOS field, focusing on their spectral properties up to redshift 1.

Contribution

It provides initial insights into the optical spectral characteristics of bright mid-IR galaxies across different IR luminosities and redshifts.

Findings

Optical spectra of bright mid-IR galaxies at z<1 are characterized.

Spectral features correlate with IR luminosity.

Results help understand galaxy evolution in IR-bright populations.

Abstract

We present here some of the first results we have obtained on the study of the optical spectra of Spitzer/MIPS 24 micron-selected galaxies in the COSMOS field. This is part of a series of studies we are conducting to analyse the optical spectral properties of mid-infrared (mid-IR) galaxies with different IR luminosities up to high redshifts. The results shown here correspond to the brightest S(24 micron)>2 mJy IR galaxy population at z<1.
