Cosmic evolution of submillimeter galaxies and their contribution to stellar mass assembly

open access: yes, 2010
The nature of galaxies selected at submillimeter wavelengths (SMGs, S_850 > 3 mJy), some of the bolometrically most luminous objects at high redshifts, is still elusive.

Antineutrino Geophysics with Liquid Scintillator Detectors [PDF]

open access: yes, 1997
Detecting the antineutrinos emitted by the decay of radioactive elements in the mantle and crust could provide a direct measurement of the total abundance of uranium and thorium in the Earth.

Optical Morphologies of Millijansky Radio Galaxies Observed by HST and in the VLA FIRST Survey

open access: yes, 2008
We report on a statistical study of the 51 radio galaxies at the millijansky flux level from the Faint Images of the Radio Sky at Twenty centimeters, including their optical morphologies and structure obtained with the Hubble Space Telescope. Our optical

A critical analysis of interpretive research studies in cooperative education and internships [PDF]

open access: yes, 2009
Much research in co-op has utilized a quantitative or experimental approach within a positivist paradigm. Here we present a critical analysis of interpretive/qualitative studies in terms of output, diversity, quality, along with an overview of the topics

The HELLAS2XMM Survey. XII. The infrared/sub-millimeter view of an X-ray selected Type 2 quasar at z=2

open access: yes, 2009
We present multi-wavelength observations (from optical to sub-millimeter, including Spitzer and SCUBA) of H2XMMJ 003357.2-120038 (also GD158_19), an X-ray selected, luminous narrow-line (Type 2) quasar at z=1.957 selected from the HELLAS2XMM survey.

The Chandra Deep Field North Survey. IX. Extended X-ray Sources

open access: yes, 2001
The ~1 Ms Chandra Deep Field North observation is used to study the extended X-ray sources in the region surrounding the Hubble Deep Field North (HDF-N), yielding the most sensitive probe of extended X-ray emission at cosmological distances to date.

Generalized Height-diameter Models for Acacia Mangium Willd. Plantations in South Sumatra [PDF]

open access: yes, 2010
The aim of this study was to develop a generalized height-diameter model for predicting tree height of Acacia mangium plantations in South Sumatra that could account for the variability of site and stand conditions.
