Astrophysics Collaborations Network

Weighted network of co-authorships between scientists posting preprints

Weighted network of co-authorships between scientists posting preprints on the Astrophysics E-Print Archive between Jan 1, 1995 and December 31, 1999. The edge weight indicates the strength of the collaboration between pairs of individuals.

(16706 vertices, 121251 edges)

Examples

Basic Examples

Retrieve the graph:

In[1]:=
ResourceData["Astrophysics Collaborations Network"]
Out[1]=

View a property summary:

In[2]:=
ResourceData["Astrophysics Collaborations Network", "Summary"]
Out[2]=

Basic Applications

Visualize the network of the neighborhood around the author with the most collaborations:

In[3]:=
g = ResourceData["Astrophysics Collaborations Network"];
In[4]:=
vertex = First[MaximalBy[VertexList[g], VertexDegree[g, #] &]]
Out[4]=
In[5]:=
NeighborhoodGraph[g, vertex, Sequence[ VertexLabels -> {vertex -> Placed["Name", Above]}, VertexStyle -> (vertex -> Red), EdgeStyle -> Opacity[0.1]]]
Out[5]=
