Analyzing the Clustering of Point Sources in the 74 MHz VLSS
By John Capodilupo
Looking up at night, it is easy to get lost in the grandeur of the view. Space seems infinite and the myriad stars inspire a multitude of feelings. Ever since I can remember, I wanted to understand the great mysteries of the universe first getting excited via buzz words like “black holes” and “curved space time.” Such fascinating ideas easily captivated my childhood curiosity . . . My interest started to become more tangible in elementary school when the school’s librarian recommended me to read Stepehen Hawking’s “A Brief History of Time.” With the help of my father I finished the book and became noticeably more interested in astrophysics. I began dreaming of becoming a research scientist much like Einstein and discovering how the universe “works.” . . . My research project looked at a mathematical function called the two-point correlation function and applied it to measure the clustering of galaxies in a radio survey of the sky. This is important because it was the first time such an analysis was done in a frequency relevant to a new area of astrophysics called 21 cm tomography which hopes to give us precise measurements of cosmological parameters and insight into the very early universe…
