How to Modelize Dwarf Spheroidal Galaxies for Predicting Gamma Ray Flux?

[Atakor]

Hello !

I want to modelize a Dsph, stellar and dark matter distributions.
In particular, I'm interested in the new discovered dSphs in the Local group, as Ursa Minor, Willman, Draco..
The aim of my study is to predict the gamma ray flux due to the annihilation of dark matter particles in these objects.
(Dsph are the most dominated DM dominated systems in the universe -for now)

so, just to start..
What are the data we have ?
velocities ? velocity dispersions?

I hope a rich debate will be engaged.
Thanks.

Yes, the data that is available for these dwarf spheroidal galaxies (dSphs) includes their velocities and velocity dispersions. There is also some information about the stellar distributions and the dark matter distributions. To modelize these distributions, you can use a variety of methods such as numerical simulations, analytical models, or a combination of both. You can also use observational data, such as photometric data, to constrain the parameters of your models. Additionally, you may want to consider the effects of baryonic physics on the dynamics of the system, such as the influence of supernova explosions and stellar winds. Once you have a model of the stellar and dark matter distributions, you can then use it to predict the gamma ray flux due to dark matter annihilation.
