Star-Forming Galaxies in the Sloan Digital Sky Survey -- The View from Pittsburgh
Regina E. Schulte-Ladbeck, Christopher J. Miller, Ulrich Hopp +4
We used data from the Data Release 1 (DR1) of the Sloan Digital Sky Survey (SDSS) in order to define a catalog of about 13,000 star-forming galaxies (SFG). We discuss the results o…
Limits on thermal conduction in galaxy clusters
Mikhail V. Medvedev, Adrian L. Melott, Chris Miller +1
We have calculated lower limits for the global effective thermal conductivity in a sample of 165 Abell clusters. We assumed that cluster X-ray luminosity is compensated by a conduc…
Non-Parametric Inference in Astrophysics
Larry Wasserman, Christopher J. Miller, Robert C. Nichol +6
We discuss non-parametric density estimation and regression for astrophysics problems. In particular, we show how to compute non-parametric confidence intervals for the location an…
A Non-parametric Analysis of the CMB Power Spectrum
Christopher J. Miller, Robert C. Nichol, Christopher Genovese +1
We examine Cosmic Microwave Background (CMB) temperature power spectra from the BOOMERANG, MAXIMA, and DASI experiments. We non-parametrically estimate the true power spectrum with…
Wavelength Doesn't Matter: Optical vs. X-ray Luminosities of Galaxy Clusters
Christopher J. Miller, Adrian L. Melott, Robert C. Nichol
We examine the relationship between the total X-ray and optical luminosities of groups and clusters of galaxies taken from various samples in the literature. The clusters and group…
