The Serendipitous Extragalactic X-Ray Source Identification (SEXSI) Program. III. Optical Spectroscopy
Megan E. Eckart, Daniel Stern, David J. Helfand +3
We present the catalog of 477 spectra from the Serendipitous Extragalactic X-ray Source Identification (SEXSI) program, a survey designed to probe the dominant contributors to the…
The Serendipitous Extragalactic X-Ray Source Identification (SEXSI) Program: II. Optical Imaging
Megan E. Eckart, Elise S. Laird, Daniel Stern +3
The Serendipitous Extragalactic X-ray Source Identification (SEXSI) Program is designed to expand significantly the sample of identified extragalactic hard X-ray sources at interme…
A Galaxy at z = 6.545 and Constraints on the Epoch of Reionization
Daniel Stern, Sarah A. Yost, Megan E. Eckart +5
We report the discovery of a Lyman-alpha-emitting galaxy at redshift z=6.545 serendipitously identified in the course of spectroscopic follow-up of hard X-ray sources on behalf of…
The Serendipitous Extragalactic X-Ray Source Identification (SEXSI) Program: I. Characteristics of the Hard X-Ray Sample
Fiona A. Harrison, Megan E. Eckart, Peter H. Mao +2
The Serendipitous Extragalactic X-ray Source Identification (SEXSI) Program is designed to extend greatly the sample of identified extragalactic hard X-ray 2-10 keV sources at inte…
Optical and Near-Infrared Spectroscopy of a High-Redshift, Hard X-ray Emitting Spiral Galaxy
Steve Dawson, Nate McCrady, Daniel Stern +4
We present optical and near-infrared Keck spectroscopy of CXOHDFN J123635.6+621424 (hereafter HDFX28), a hard X-ray source at a redshift of z = 2.011 in the flanking fields of the…
