资源简介:

The three N-body snapshot files included in the .tar.gz correspond to each NSC in the manuscript. Each snapshot includes all particles from the simulation (background galaxy, NSC/GC particles). Data inside the snapshots is arranged as follows: First three lines are the header of the snapshot, arranged as:[snapshot number][total # particles] [# of BH particles] [# of DM particles] [# of stellar particles][Snapshot time] After the header starts the main body of the snapshot, where each row contains information about a particle in the simulation. The columns are arranged as:Col 1: particle index (goes from 0 to max # particles). Col 2: particle mass. Cols 3, 4, 5: x, y, z position of particle, respectively. Cols 5, 6, 7: vx, vy, vz velocities of particle, respectively. Col 8: Softening used for particle For snapshots nsc1.dat and nsc2.dat, the first 75083 particles correspond to the GC particles (from index 0 to 75082, particles from which the NSC is also made of). For snapshot nsc3.dat, the first 396351 particles correspond to GC particles (from index 0 to 396350). All quantities in the snapshots are given in N-body units. Use the following conversion factors to convert to physical units: [L] = 1 pc for nsc1.dat and nsc2.dat.[L] = 100 pc for nsc3.dat [M] = 5e8 solar masses [T] = 0.0006667 Myr for nsc1.dat and nsc2.dat[T] = 0.6667 Myr for nsc3.dat [V] = 1464.624 km/s for nsc1.dat and nsc2.dat[V] = 146.462 km/s for nsc3.dat
