A Simulation.of the Depen.en.e of Tidal In.eraction.on.Galaxy Type in.Compact Groups

引用

In.ern.tion.l j.urn.l of Astron.my an. Astrophysics 2024年第2期14卷 85-100页

作者： Mark j. Hen.iksen.Mateo Mej.a Departmen. of Physics University of Maryland Baltimore USA

We have in.estigated the role that differen. galaxy types have in.galaxy-galaxy in.eraction. in.compact groups. n.body simulation. of 6 galaxies con.istin. of a differin. mixture of galaxy types were run.to compare the relative importan.e of galaxy population.demographic on.evolution. Three differen. groups with differin. galaxy con.en. were tested: all spiral, a sin.le elliptical an. 50% elliptical. Tidal in.eraction.stren.th an. duration.were recorded to assess the importan.e of an.in.eraction. A group with an.equal n.mber of spiral an. elliptical galaxies has some of the lon.est an. stron.est in.eraction. with elliptical-elliptical in.eraction. bein. most sign.fican.. These elliptical-elliptical in.eraction. are n.t domin.ted by a sin.le large even. but con.ist of multiple in.eraction.. Elliptical galaxies tidally in.eractin. with spiral galaxies, have the n.xt stron.est in.eraction.even.s. For the case when.a group on.y has a sin.le elliptical, the largest magn.tude tidal in.eraction.is an.elliptical on.a spiral. Spirals in.eract with each other through man. small in.eraction.. For a spiral on.y group, the in.eraction. are the weakest compared to the other group types. These spiral in.eraction. are n.t domin.ted by an. sin.ular even. that might be expected to lead to a merger but are more of an.on.oin. harassmen.. These results suggest that within.a compact group, early type galaxies will n.t form via merger out of an.assemblage of spiral galaxies but rather that compact groups, in.effect form aroun. an.early type galaxy.
