DESCRIPTION:Stellar counter-rotation (CR)\, where a large fraction of stars
  rotate opposite to the old stellar disk\, is a striking dynamical signatur
 e of past galaxy interactions. Such kinematically decoupled structures are 
 thought to form after the accretion of gas or during fine-tuned collisions 
 of galaxies that bring in material with opposite angular momentum. Using Ma
 NGA survey data\, we have identified over one hundred CR galaxies\, but one
  system stands out: NGC 5717\, the most massive known CR galaxy. This galax
 y is a brightest cluster galaxy\, morphologically resembling an elliptical 
 with an embedded\, massive disk with young stellar population and ongoing s
 tar formation. The scale and persistence of this structure in a dense envir
 onment challenge current views on how disks survive and reform after mergin
 g. In this talk\, I will present the sample of such galaxies\, the properti
 es of NGC 5717\, and discuss its implications for understanding disk assemb
 ly and the role of galaxy collisions in shaping CR-galaxies.\n\nImported fr
