COSMOLOGY

1 Hyeonmo's Report

Speaker: Hyeonmo Koo (University of Seoul)

Head-on Collision Fuzzy/Cold Dark Matter Halos

• Made fitting function.
• CDM is larger cooling effects than FDM.
• Deriving arguments carefully.

2 Young's report. FoF and MST algorithm

Speaker: Young Ju

FoF and MST Algorithm

• Test MGS and MST on two-dimensional random data.
  • 1. There three clusters & each cluster has 50 galaxies.
  • 2. The galaxies are spread by the Gaussian distribution (Standard deviation = 10).
  • 3. Linking-length = 10.0
• Organize order of density.

3 Hannah's Report

Speaker: Hannah Jhee (University of Seoul)

Halos infalling a cluster through filaments

• Δt is zero. → Non-revolving.
• Refer to Poisson's equation.

4 Seyeon's Report - CLML

Speaker: Se Yeon Hwang (Universe of Seoul)

Cosmology with Large scale structure using Machine Learning (CLML)

• No progress

5 Sumi's report

Speaker: Sumi Kim (University of Seoul)

Cosmology of High-Order Statistics (CHOA)

• Used n-point correlation function.

6 Dr.Sabiu's Report

Speaker: Dr Cristiano Sabiu (University of Seoul)

Deep Learning the Deep Sky: Recovering low surface brightness objects with machine learning

• No progress
