LIRGI includes 42 local (D < 260 Mpc) galaxies of the most luminous infra-red galaxies selected from the IRAS revised Bright Galaxy Sample in the Northern Hemisphere, with L= log(Lir/Lsol) >11.4. The galaxies of the sample have properties of area star formation densities, gas and radiation densities similar to star-forming galaxies a high redshift. LIRGI will provide a much needed high-spatial resolution radio complement to the legacy observations made with the NASA Great Observatories (GOALS). The e-MERLIN LIRGI project has observed at C- and L-band (both in continuum and spectra line mode), as well as EVN for the whole sample, and access to LOFAR data for a sub-sample of LIRGI. In addition, there is ancillary JVLA data for the whole sample. This project exploits the combined dataset of e-MERLIN/LOFAR/JVLA, to trace the nature of the ISM in LIRGs (clumpy vs. uniform media), as well as for unveiling nuclear outflows.

LIRGI 包括从北半球 IRAS 修订的明亮星系样本中选出的最亮红外星系中的 42 个本地 (D < 260 Mpc) 星系，L= log(Lir/Lsol) >11.4。样本星系具有与恒星形成星系相似的区域恒星形成密度、气体和辐射密度的特性以及高红移。 LIRGI 将为 NASA 大天文台 (GOALS) 的传统观测提供急需的高空间分辨率无线电补充。 e-MERLIN LIRGI 项目在 C 和 L 波段（连续谱和谱线模式）以及整个样本的 EVN 进行了观测，并获取了 LIRGI 子样本的 LOFAR 数据。此外，还有整个样本的辅助 JVLA 数据。该项目利用 e-MERLIN/LOFAR/JVLA 的组合数据集，追踪 LIRG 中 ISM 的性质（块状介质与均匀介质），并揭示核外流。
