Study of the Correlations of the Properties of the Host Galaxy Based on a Sample of Spitzer/ IRAS Spiral Galaxies

EasyChair Preprint 1879

Abstract

A sample of 40 Spitzer/IRAS (3.6µm) spiral galaxies was selected. This sample consisted of ranging of Hubble types from Sa to Sc to discover new correlations. The total mass (M⋆) of the stellar associated with the subhalo was used, which it finds directly from the simulation outputs. We used a large sample of accurate estimates of host galaxy velocity dispersions (σ*) coupled with libraries of the total mass of the stellar (M^∗), total mass of halo (M_halo), and mass of dark matter (M_DM), of the host galaxies. We explored correlations between the spheroid velocity dispersion (σ*) and mass of the total stellar (M∗) (σ*-M∗), the mass of dark matter (M_DM) (σ*-M_DM) and, the mass of total halo (M_halo) (σ*-M_halo) of host galaxies.

Keyphrases: Spiral Galaxies, dark matter, dispersion velocity, halo mass
