HIGHLIGHTS

• who: Junais and colleagues from the CNRS, CNES, LAM, France Department of Physics and, Stony Brook University, Stony Brook, NY, USA have published the research: First spectroscopic study of ionised gas emission lines in the extreme low surface brightness galaxy Malin 1, in the Journal: (JOURNAL)
• what: The authors show that in the inner regions dynamics may be dominated by the stars (although none of the models can explain the highest velocities measured) but that at large radii massive dark matter halo remains necessary.
• how: The authors compared the data with existing data . . .
