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…
