On the origin of outward migration of Population III stars
Jongwon Park, Massimo Ricotti, Kazuyuki Sugimura
Outward migration of massive binary stars or black holes in their circumbinary disc is often observed in simulations and it is key to the formation of wide black hole binaries. Usi…
Star Cluster Formation and Survival in the First Galaxies
Fred Angelo Batan Garcia, Massimo Ricotti, Kazuyuki Sugimura +1
Using radiation-hydrodynamic cosmological simulations, we present a detailed ( pc resolution), physically motivated portrait of a typical-mass dwarf galaxy before the epoch of…
Population III star formation in an X-ray background: III. Periodic radiative feedback and luminosity induced by elliptical orbits
Jongwon Park, Massimo Ricotti, Kazuyuki Sugimura
We model Pop III star formation in different FUV and X-ray backgrounds, including radiation feedback from protostars. We confirm previous results that a moderate X-ray background i…
Population III Star Formation in an X-ray background: II. Protostellar Discs, Multiplicity and Mass Function of the Stars
Jongwon Park, Massimo Ricotti, Kazuyuki Sugimura
Disc fragmentation plays an important role in determining the number of primordial stars (Pop III stars), their masses, and hence the initial mass function. In this second paper of…
Population III Star Formation in an X-ray background: I. Critical Halo Mass of Formation and Total Mass in Stars
Jongwon Park, Massimo Ricotti, Kazuyuki Sugimura
The first luminous objects forming in the universe produce radiation backgrounds in the FUV and X-ray bands that affect the formation of Population III stars. Using a grid of cosmo…
Star Formation of Merging Disk Galaxies with AGN Feedback Effects
Jongwon Park, Rory Smith, Sukyoung K. Yi
Using numerical hydrodynamics code, we perform various idealized galaxy merger simulations to study the star formation (SF) of two merging disk galaxies. Our simulations include ga…
