摘　　要：(极)亮红外星系在星系演化过程中扮演了重要的角色,其主要由富气体的旋涡星系并合形成,并伴随着剧烈的恒星形成活动以及可能的活动星系核活动。受星暴和活动星系核加热的尘埃在红外波段的再辐射使这类星系有极高的红外光度。随着各种先进天文观测设备的投入使用,对近邻宇宙中(极)亮红外星系的观测研究取得了许多重要进展。首先介绍了由最新研究获得的近邻(极)亮红外星系在各波段的观测特征,然后介绍了与近邻(极)亮红外星系相关的研究热点,最后讨论了未来相关的研究计划。(Ultra)Luminous infrared galaxies((U)LIRGs,LIR>1011(12)L⊙)play an important role in the evolution of galaxies.Most of the(U)LIRGs are the consequences of mergers between gas-rich spirals,which lead to intense starbursts and possible AGN activity.The re-emission from the dust heated by starbursts and/or AGN is a key process that is responsible for the high infrared luminosity of(U)LIRGs.With the rapid development of instruments,substantial progress has been made in observing nearby(U)LIRGs.In this review article,we first present the multi-wavelength properties of nearby(U)LIRGs obtained by the latest observational studies.Then,we introduce several research topics relating to(U)LIRGs.Future observing plans are also discussed at the end of this paper.
