DESCRIPTION:Nuclear star clusters (NSCs) are found in at least 70% of all g
 alaxies\; however\, despite their abundance it is still debated how they f
 orm. The currently discussed scenarios propose that NSCs could either form
  from infalling gas directly at the galactic center or through the accreti
 on of globular clusters (GCs) that spiral inwards due to dynamical frictio
 n\, but also a composite scenario is possible. In the GC accretion scenari
 o\, the NSC would reflect the low angular momentum and low metallicities o
 f the surrounding GC population\, whereas the in-situ scenario would lead 
 to a higher angular momentum and higher metallicities from subsequent star
  bursts.\nConstraining NSC formation in galaxies therefore requires a comp
 lete view of both the kinematics and chemical properties of the host galax
 y\, the NSC and the GC system. To achieve this task\, we use IFU data from
  the MUSE instrument of the early-type galaxy FCC47\, which has a remarkab
 ly large NSC (Reff ~ 66 pc) and a very rich GC system.\nIn addition to an 
 analysis of the galaxy light kinematics and stellar population properties\
 , we extract optical spectra of the GCs to determine radial velocities and
  metallicities. In combination with a dynamical model\, our panoramic view
  of the galaxy and its star clusters allows to put constraints on the form
 ation of FCC47’s massive NSC. https://astronomia.uc.cl/2jucext1/institutoa
