The Dark Energy Survey Data Management System
Joseph J. Mohr, Wayne Barkhouse, Cristina Beldica +17
The Dark Energy Survey collaboration will study cosmic acceleration with a 5000 deg2 griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM…
Molecular hydrogen adsorbed on benzene: insights from a quantum Monte Carlo study
Todd D. Beaudet, Michele Casula, Jeongnim Kim +2
We present a quantum Monte Carlo study of the hydrogen-benzene system where binding is very weak. We demonstrate that the binding is well described at both variational Monte Carlo…
Robust Machine Learning Applied to Terascale Astronomical Datasets
Nicholas M. Ball, Robert J. Brunner, Adam D. Myers
We present recent results from the LCDM (Laboratory for Cosmological Data Mining; http://lcdm.astro.uiuc.edu) collaboration between UIUC Astronomy and NCSA to deploy supercomputing…
Robust Machine Learning Applied to Astronomical Datasets III: Probabilistic Photometric Redshifts for Galaxies and Quasars in the SDSS and GALEX
Nicholas M. Ball, Robert J. Brunner, Adam D. Myers +3
We apply machine learning in the form of a nearest neighbor instance-based algorithm (NN) to generate full photometric redshift probability density functions (PDFs) for objects in…
Molecular Line Observations of the SiO Maser Source IRAS 19312+1950
Jun-ichi Nakashima, Shuji Deguchi, Hiroshi Imai +1
IRAS 19312+1950 is a unique SiO maser source, exhibiting a rich set of molecular radio lines, although SiO maser sources are usually identified as oxygen-rich evolved stars, in whi…
