[O I] 63 micron Emission from High and Low Luminosity AGN Galaxies

Daniel A. Dale, George Helou, James R. Brauher +3

The Infrared Space Observatory was used to search for a tracer of the warm and dense neutral interstellar medium, the [O I] 63.18 micron line, in four ultraluminous IRAS sources ly…

Three Lyman-alpha Emitters at z approx 6: Early GMOS/Gemini Data from the GLARE Project

Elizabeth R. Stanway, Karl Glazebrook, Andrew J. Bunker +14

We report spectroscopic detection of three z~6 Lyman-alpha emitting galaxies, in the vicinity of the Hubble Ultra Deep Field, from the early data of the Gemini Lyman- at Reionis…

172 ks Chandra Exposure of the LALA Boötes Field: X-ray Source Catalog

J. X. Wang, S. Malhotra, J. E. Rhoads +7

We present an analysis of a deep, 172 ks Chandra observation of the Large Area Lyman Alpha Survey (LALA) Boötes field, obtained with the Advanced CCD Imaging Spectrometer (ACIS-I)…

No X-ray Bright Type II Quasars Among the Lyman-alpha Emitters

S. Malhotra, J. X. Wang, J. E. Rhoads +2

The Lyman-alpha emitters found at z=4.5 and 5.7 by the Large Area Lyman Alpha (LALA) survey have high equivalent widths in the Lyman-alpha line. Such lines can be produced by narro…

Infrared Emission of Normal Galaxies from 2.5 to 12 Microns: ISO Spectra, Near-Infrared Continuum and Mid-Infrared Emission Features

Nanyao Lu, George Helou, Michael W. Werner +6

We present ISO-PHOT spectra of the regions 2.5-4.9um and 5.8-11.6um for a sample of 45 disk galaxies from the U.S. ISO Key Project on Normal Galaxies. The spectra can be decomposed…
