Constraining Cosmology with Big Data Statistics of Cosmological Graphs

Sungryong Hong, Donghui Jeong, Ho Seong Hwang +7

By utilizing large-scale graph analytic tools implemented in the modern Big Data platform, Apache Spark, we investigate the topological structure of gravitational clustering in fiv…

Statistics of Two-point Correlation and Network Topology for Lyman Alpha Emitters at

Sungryong Hong, Arjun Dey, Kyung-Soo Lee +9

We investigate the spatial distribution of Lyman alpha emitting galaxies (LAEs) at , selected from the NOAO Deep Wide-Field Survey (NDWFS), using two-point statisti…

A census of galaxy constituents in a Coma Progenitor observed at z>3

Ke Shi, Kyoung-Soo Lee, Arjun Dey +15

We present a detailed census of galaxies in and around PC217.96+32.3, a spectroscopically confirmed Coma analog at z=3.78. Diverse galaxy types identified in the field include Lya…

Discovery of a Very Large (~20 kpc) Galaxy at z=3.72

Kyoung-Soo Lee, Arjun Dey, Thomas Matheson +12

We report the discovery and spectroscopic confirmation of a very large star-forming Lyman Break galaxy, G6025, at z_spec=3.721+/-0.003. In the rest-frame ~2100A, G6025 subtends ~24…

Spectroscopic Confirmation of a Protocluster at z=3.786

Arjun Dey, Kyoung-Soo Lee, Naveen Reddy +5

We present new observations of the field containing the z=3.786 protocluster, PC217.96+32.3. We confirm that it is one of the largest and most overdense high-redshift structures kn…

The Network Behind the Cosmic Web

B. C. Coutinho, Sungryong Hong, Kim Albrecht +5

The concept of the cosmic web, viewing the Universe as a set of discrete galaxies held together by gravity, is deeply engrained in cosmology. Yet, little is known about the most ef…
