AGN Environments in the Sloan Digital Sky Survey I: Dependence on Type, Redshift, and Luminosity
Natalie E. Strand, Robert J. Brunner, Adam D. Myers
We explore how the local environment is related to the redshift, type, and luminosity of active galactic nuclei (AGN). Recent simulations and observations are converging on the vie…
Developing and Deploying Advanced Algorithms to Novel Supercomputing Hardware
Robert J. Brunner, Volodymyr V. Kindratenko, Adam D. Myers
The objective of our research is to demonstrate the practical usage and orders of magnitude speedup of real-world applications by using alternative technologies to support high per…
Dynamic load-balancing on multi-FPGA systems: a case study
Volodymyr V. Kindratenko, Robert J. Brunner, Adam D. Myers
In this case study, we investigate the impact of workload balance on the performance of multi-FPGA codes. We start with an application in which two distinct kernels run in parallel…
Robust Machine Learning Applied to Terascale Astronomical Datasets
Nicholas M. Ball, Robert J. Brunner, Adam D. Myers
We present recent results from the Laboratory for Cosmological Data Mining (http://lcdm.astro.uiuc.edu) at the National Center for Supercomputing Applications (NCSA) to provide rob…
Quasar Clustering at $25\kpch$ from a Complete Sample of Binaries
Adam D. Myers, Gordon T. Richards, Robert J. Brunner +5
We present spectroscopy of binary quasar candidates selected from Data Release 4 of the Sloan Digital Sky Survey (SDSS DR4) using Kernel Density Estimation (KDE). We present 27 new…
Higher-Order Angular Galaxy Correlations in the SDSS: Redshift and Color Dependence of non-Linear Bias
Ashley J. Ross, Robert J. Brunner, Adam D. Myers
We present estimates of the N-point galaxy, area-averaged, angular correlation functions () for = 2,...,7 for galaxies from the fifth data release of the Sloan Di…
