<｜begin▁of▁sentence｜>### Instruction:
As a financial planner, you have been requested to utilize the Louvain method available in the CDlib library to detect communities within the collaborative network of astrophysicists, represented by the astro-ph.gml file. Following the community detection, you are asked to calculate the hub dominance score for the identified communities and display the results for further analysis and decision-making.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Load the Astrophysics collaborations graph
G = nx.read_gml('astro-ph.gml')

# Perform community detection using the Louvain method
communities = algorithms.louvain(G)

# Compute the hub dominance for the detected communities
hub_dominance_score = evaluation.hub_dominance(G, communities)

print(hub_dominance_score)
