Homework Statement
This is not an homework. This is an term project for which I have to research. I can get help from anyone unless someone is not doing everthing. I can ask questions for this project.
Relevant Equations
I donot have any equation
Hello, I have asked a similar question before, but this time I want to ask it a bit differently to be understood better.

I am a physics student at a university and this semester I am going to make a term project about Dark Matter Density Distribution by using rotation curves. However, I am a bit lost. I have checked some papers related to this topic, but have not found everything that I am looking for. I may need to research it in much more detailed. So if you have papers related to the questions that I am going to ask, I would appreciate if you provide them to me.

I want to know what I will need to have as data and the methods I am going to use, step by step.

I have data of rotation curves for some galaxies. As I saw it in some papers, I will need V_bulge , V_disk , V_gas to find out V_DM. Then, I will need to use one of the profiles such as NFW.

These are so far what I have understood or I think I understood it. Could you guide me step by step if possible provide me with data and papers, please?

Thank you all

That is not how term projects at university work: you need to find these things out for yourself.

Related to How to Approach a Term Project on Dark Matter Density Distribution?

What is dark matter density distribution?

Dark matter density distribution refers to the way dark matter is spread out or concentrated in different regions of the universe. It describes the variation in density of dark matter in space, helping scientists understand how it influences the formation and evolution of cosmic structures like galaxies and clusters.

How is dark matter density distribution measured?

Dark matter density distribution is measured indirectly through its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Methods include observing the rotation curves of galaxies, gravitational lensing, and studying the cosmic microwave background radiation. These observations help infer the presence and distribution of dark matter.

Why is dark matter density distribution important?

Understanding dark matter density distribution is crucial for explaining the formation and evolution of cosmic structures. It helps in constructing accurate models of galaxy formation, understanding the large-scale structure of the universe, and providing insights into the nature of dark matter itself, which remains one of the biggest mysteries in cosmology.

What are the challenges in studying dark matter density distribution?

One of the main challenges is that dark matter does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects. This indirect detection requires precise measurements and sophisticated modeling. Additionally, distinguishing dark matter effects from other astrophysical phenomena adds complexity to the study.

What are the current models of dark matter density distribution?

Current models of dark matter density distribution include the Cold Dark Matter (CDM) model, which suggests that dark matter consists of slow-moving particles that clump together under gravity. Another model is the Warm Dark Matter (WDM) model, which proposes slightly faster-moving particles. These models are used to simulate and predict the distribution of dark matter in the universe, with the CDM model being the most widely accepted.
