Evolution of Star-forming Galaxies seen from Lyman Break Galaxies at $z\sim5$

TL;DR

This paper investigates the properties and evolution of Lyman Break Galaxies from redshift 5 to 2-3, highlighting their smaller stellar masses but high star formation activities at earlier cosmic times.

Contribution

It provides a comparative analysis of LBG properties at different redshifts, revealing evolutionary trends in stellar mass and star formation rates.

Findings

LBGs at z~5 have smaller stellar masses.

They exhibit high star formation rates.

Specific star formation rates are also large at z~5.

Abstract

Properties of Lyman Break Galaxies at $z\sim5$ are presented and are compared with those at $z\sim 2-3$ LBGs to see evolution of LBGs from $z\sim5$ to $z \sim3-2$. The LBGs at $z\sim5$ are tend to have smaller stellar masses, but they may show large star formation rates and specific star formation rates.
