Warm molecular hydrogen in nearby LIRGs

Mid-infrared molecular hydrogen (H_2_) emission is a powerful cooling agent in galaxy mergers and in radio galaxies; it is a potential key tracer of gas evolution and energy...中红外（Mid-infrared）波段的分子氢（Molecular Hydrogen, H₂）辐射是星系并合与射电星系（Radio Galaxies）中一种强效的冷却剂；它亦是气体演化与能量……的潜在关键示踪剂（tracer）。
