... Untangling an extremely warped dwarf galaxy . ... Warps in neutral hydrogen (HI) disks are common in spiral galaxies. ... To do this in many hundreds of galaxies we have developed a code that can fit all kinds of warps in HI disks, the Fully Automated Tilted Ring Fitting Code (FAT, Kamphuis et al. 2015, submitted). ... With FAT we can now apply this fitting technique to a large sample and thus investigate the origin of warps. | ... today * ATNF | ...
