<｜begin▁of▁sentence｜>### Instruction:
Given the Astrophysics collaborations graph which you can read from a GML file named astro-ph.gml, can you use the Asynchronous Fluid Communities detection algorithm from cdlib to detect 3 communities within the collaborative network? Please provide the JSON representation of the detected communities after running the algorithm.
### Response:
import networkx as nx
from cdlib import algorithms

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

# Apply the Asynchronous Fluid Communities algorithm to find 3 communities
coms = algorithms.async_fluid(G, k=3)

# Convert communities to JSON object
coms_json = coms.to_json()

# Print the JSON representation of the detected communities
print(coms_json)
