Optical SED models of galaxy mergers

Starburst in multiple galaxy mergers

We numerically investigate stellar and gaseous dynamical evolution of mergers between five identical late-type disk galaxies with the special emphasis on star formation history and chemical evolution of multiple galaxy mergers. We found that multiple encounter and merging can trigger repetitive massive starbursts (typically ∼ 100 M yr−1) owing to the strong tidal disturbance and the resultant g...

3D ISM-Shock Spectral Emission: X-ray models for Radio Galaxy SED Modeling

Galaxies form out of small fluctuations in a smoothly expanding Universe. However, the initial gravitational collapse phase is accompanied by the formation of supermassive black holes and clusters of massive stars. Black holes and star clusters generate powerful outflows in the form of jets and superwinds that interact with still infalling gas, possibly regulating the galaxy formation process, ...

Formation of globular clusters in galaxy mergers

Our numerical simulations first demonstrate that the pressure of ISM in a major merger becomes so high (> 105 kB K cm−3) that GMCs in the merger can collapse to form globular clusters (GCs) within a few Myr. The star formation efficiency within a GMC in galaxy mergers can rise up from a few percent to ∼ 80 percent, depending on the shapes and the temperature of the GMC. This implosive GC format...

Formation of Globular Clusters in Galaxy Mergers

We present a high-resolution simulation of globular cluster formation in a galaxy merger. For the first time in such a simulation, individual star clusters are directly identified and followed on their orbits. We quantitatively compare star formation in the merger to that in the unperturbed galaxies. The merging galaxies show a strong starburst, in sharp contrast to their isolated progenitors. ...
