・HI gas falls down due to close encounter of LMC & SMC
・Fast(~100km/s) HI gas collision occur @LMC
・Massive Star clusters are formed in HI gas colliding region

Compact gas clump?
Detailed analysis

Gas clump in shock compressed layer

10/15

What is the gas that forms the star cluster?

Gas needs to be packed into a compact
area before star formation occurs➢ We identify dense gas clumps➢ Is star formation is occurringat the clump

Dense clumps are identiﬁed by friend-of-friend algorithm

Future work
Parameter survey will be done by future work
(metallicity , B-ﬁeld , collision speed …)
Lagrangian dynamics of clumps will be studied (Test particles)
