Correlation between Hα Emitters and Their Cosmic Web Environment at z ∼ 1

The Astrophysical Journal
Future near-infrared spectroscopic galaxy surveys will target high-redshift emission-line galaxies (ELGs) to test cosmological models. Deriving optimal constraints from ELG clustering hinges on a robust understanding of their environmental dependence ...

Optical polarimetry studies of Seyfert galaxies [PDF]

, 1999
Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.

What powers luminous infrared galaxies?

Astronomy & Astrophysics, 1996
Based on the initial data sets taken with the ISO short wavelength spectrometer (SWS) we present a first discussion of the source of luminosity of (ultra-)luminous infrared galaxies (ULIRGs). By comparison of observations of 2.5-45 mu m lines to classical starbursts and active galactic nuclei and by modelling of the line emission we show that three key

Measuring the star formation rate density from CNOC2 [PDF]

, 2006
This thesis charts the evolution of the Universal Star Formation Rate Density (SFRD) across the redshift range 0.2 < z < 0.6, using the 2nd Canadian Network for Observational Cosmology Survey (CN0C2).

The evolution of luminous infrared galaxies through cosmic time [PDF]

(Ultra) Luminous infrared galaxies (U/LIRGs) are amongst the most powerful star forming galaxies in the universe. They play a significant role in galaxy evolution and dominate the star formation rate density at the peak of cosmic star formation, at z ∼ 2.

Characterizing the Molecular Gas in Infrared Bright Galaxies with CARMA

The Astrophysical Journal
We present the CO(1–0) maps of 28 infrared-bright galaxies from the Great Observatories All-Sky Luminous Infrared Galaxy Survey (GOALS) taken with the Combined Array for Research in Millimeter Astronomy (CARMA).

The location and kinematics of the emission line regions in Active Galactic Nuclei [PDF]

, 2008
This thesis contains the results from a study of the optical emission lines of various samples of active galactic nuclei (AGN). We have used three separate techniques to determine the precise kinematics and the relative location of the emission line ...

A Spitzer/IRS Study of Local Luminous Infrared Galaxies

, 2010
We present the first results of our program to study a sample of local luminous infrared galaxies (LIRGs, L_IR = 10^11-10^12 L_sun) with the Spitzer infrared spectrograph (IRS). In these proceedings we investigate the behavior of the 9.7 um silicate feature in LIRGs.
