Malin 1, being a class of giant low surface galaxies, continues to surprise us even today. The HST/F814W observation has shown that the central region of Malin 1 is more like a normal SB0/a galaxy, while the rest of the disk has the characteristic of a low surface brightness system. The AstroSat/UVIT observations suggest scattered recent star formation activity all over the disk, especially along the spiral arms. The central \(9''\) (\(\sim 14\,\hbox {kpc}\)) region, similar to the size of the Milky Way’s stellar disk, has a number of far-UV clumps—indicating recent star-formation activity. The high resolution UVIT/F154W image reveals far-UV emission within the bar region (\(\sim 4\,\hbox {kpc}\))—suggesting the presence of hot, young stars in the bar. These young stars from the bar region are perhaps responsible for producing the strong emission lines such as H\(\alpha \), [Oii] seen in the SDSS spectra. Malin 1B, a dwarf early-type galaxy, is interacting with the central region and probably responsible for inducing the recent star-formation activity in this galaxy.

马林 1 是一类巨大的低表面星系，即使在今天，它仍然让我们感到惊讶。HST/F814W观测表明，马林1的中心区域更像一个正常的SB0/a星系，而盘的其余部分则具有低表面亮度系统的特征。AstroSat/UVIT 的观测表明，整个圆盘上都有散布的近期恒星形成活动，尤其是沿着旋臂。中央的\(9''\) ( \(\sim 14\,\hbox {kpc}\) ) 区域与银河系的星盘大小相似，有许多远紫外线团块——表明最近的恒星- 形成活动。高分辨率 UVIT/F154W 图像揭示了条形区域内的远紫外线发射 ( \(\sim 4\,\hbox {kpc}\))——暗示酒吧里有炙手可热的年轻明星。这些来自棒区的年轻恒星可能是产生强发射线的原因，例如在 SDSS 光谱中看到的H \(\alpha \) , [O ii ]。马林 1B 是一个矮早型星系，它正在与中心区域相互作用，可能是诱发该星系近期恒星形成活动的原因。
