The MUSE <i>Hubble</i> Ultra Deep Field Survey

We investigate the specific angular momentum (sAM) j (&lt; r ) profiles of intermediate redshift (0.4 &lt; z 1.4) star-forming galaxies (SFGs) in relatively unexplored regime low masses (down to M ⋆ ∼ 10 8 ⊙ and small sizes R e 1.5 kpc), we characterize sAM scaling relation (i.e., Fall relation) its evolution. have developed a 3D methodology constrain gas using forward modeling approach with G A lP K that incorporates effects beam smearing, yielding intrinsic morpho-kinematic properties even limited spatial resolution data.
