Chandra Deep Field South: The 1 Ms Catalog (2002, background): “This population of sources has been already partially identified as nearby, bright normal galaxies by Tozzi et al. (2001), Hornschemeier et al. (2001), and Barger et al. (2001).”
A CHANDRA PERSPECTIVE ON GALAXY-WIDE X-RAY BINARY EMISSION AND ITS CORRELATION WITH STAR FORMATION RATE AND STELLAR MASS: NEW RESULTS FROM LUMINOUS INFRARED GALAXIES (2010, methodology): “For each of the three bands, we constructed corresponding exposure maps following the basic procedure outlined in§3.2 of Hornschemeier et al. (2001); these maps were normalized to the effective exposures of sources located at the aim points.”
An Overview of the Performance and Scientific Results from the Chandra X‐Ray Observatory (2001, background): “…these galaxies, located in the HDF-N, the X-ray emission appears to be nonnuclear, based on the offset from the center of the optical light distribution, perhaps implying on the basis of the high X-ray luminosity that intermediate-mass black hole candidates are present (Hornschemeier et al. 2001b).”
THE XMM-NEWTON WIDE-FIELD SURVEY IN THE COSMOS FIELD (XMM-COSMOS): DEMOGRAPHY AND MULTIWAVELENGTH PROPERTIES OF OBSCURED AND UNOBSCURED LUMINOUS ACTIVE GALACTIC NUCLEI (2010, background): “Since the first source identification campaigns of hard X–rays surveys, a class of sources with high (> 10) X-ray-to-optical flux ratio (X/O6; Hornschemeier et al. 2001, Alexander et al. 2001; Giacconi et al. 2001; F03; Koekemoer et al. 2004; Eckart et al. 2006) has been found.”
The Chandra Deep Field North Survey. VI. The Nature of the Optically Faint X-Ray Source Population (2001, background): “The optical spectroscopic identification of the optically brighter (I < 24) X-ray sources is currently in progress, and the majority of the sources appear to be AGN atz <∼ 1 (e.g., Hornschemeier et al. 2001, hereafter Paper II; Tozzi et al. 2001;A.J. Barger et al. , in preparation).”
Spitzer Observations of Massive, Red Galaxies at High Redshift (2005, background): “Twelve of the 13 X-ray– detected DRGs withM 1011 M have X-ray–to–optical flux ratios log ( fX / fR) 1:0 [the remaining one has log ( fX/fR) 1:4], and these imply the presence of an AGN with LX k 1042 ergs s 1 for DRGs at zk 1:5 (e.g., Hornschemeier et al. 2001; Alexander et al. 2003).”
A Spectroscopic Survey of Redshift 1.4 ≲ z ≲ 3.0 Galaxies in the GOODS-North Field: Survey Description, Catalogs, and Properties (2006, background): “…et al. 2005), (2) direct detection in theChandra 2Ms data (Alexander et al. 2003) and an X-rayYtoYoptical flux ratio indicative of AGNs (see, e.g., Hornschemeier et al. 2001; Reddy et al. 2005), or (3) an 8 and 24 m flux excess above what one would expect from a simple star-forming population.”
Spitzer View on the Evolution of Star-forming Galaxies from z = 0 to z ~ 3 (2005, background): “…inMIR-FIR surveys, estimated in the range 10%–20% by several authors based on local samples (Rush et al. 1993), X-ray identifications consistent with an active galaxy (Brandt et al. 2001; Hornschemeier et al. 2001; Fadda et al. 2002; Rigby et al. 2004), and other methods (La Franca et al. 2004).”
“Hidden” Seyfert 2 Galaxies and the X-Ray Background (2002, methodology): “For the scans, the width of the slit was increased to 6′′ to improve our observing efficiency and to degrade the spectral resolution to 15–16 Å, comparable to that used in observations of faint Chandra sources (Barger et al. 2002; Hornschemeier et al. 2001).”
THE 2 Ms CHANDRA DEEP FIELD-NORTH SURVEY AND THE 250 Ks EXTENDED CHANDRA DEEP FIELD-SOUTH SURVEY: IMPROVED POINT-SOURCE CATALOGS (2016, methodology): “Following the basic procedure detailed in Section 3.2 of Hornschemeier et al. (2001), we produce effective-exposure maps for the three standard bands and normalize them to the effective exposures of a pixel lying at the average aim point, assuming a photon index of G = 1.4 that is the slope of the…”
Spitzer Power-Law Active Galactic Nucleus Candidates in the Chandra Deep Field-North (2007, background): “REDSHIFTS Twenty one of the power-law galaxies have secure spectroscopic redshifts (Barger et al. 2001, 2002, 2003; Hornschemeier et al. 2001; Dawson et al. 2003; Cowie et al. 2004; Swinbank et al. 2004; Wirth et al. 2004 [Team Keck Redshift Survey]; Chapman et al. 2005; the Sloan Digital Sky…”
The Bulk of the Cosmic Infrared Background Resolved by ISOCAM (2002, methodology): “The deepest soft plus hard X-ray observation currently available was performed with the Chandra X-ray Observatory in the HDFN by Hornschemeier et al. (2001) and Brandt et al. (2001, 2002).”
THE CHANDRA COSMOS LEGACY SURVEY: OPTICAL/IR IDENTIFICATIONS (2015, background): “Chandra and XMM-Newton studies extended this relation to harder bands (Hornschemeier et al. 2001, 2-8 keV; Alexander et al. 2001, 2-8 keV; Giacconi et al. 2002, 0.5-10 keV; Fiore et al. 2003, 2-10 keV; Della Ceca et al. 2004, 4.5-7.5 keV; Cocchia et al. 2007, 2-10 keV).”
INNOVATIONS IN THE ANALYSIS OF CHANDRA-ACIS OBSERVATIONS (2010, methodology): “This technique has been widely used in Chandra deep extragalactic field studies (e.g., Hornschemeier et al. 2001; Brandt et al. 2001; Lehmer et al. 2007).”
THE CHANDRA COSMOS SURVEY. III. OPTICAL AND INFRARED IDENTIFICATION OF X-RAY POINT SOURCES (2012, methodology): “With the advent ofChandraand XMM-Newton, the same relation has been used in harder bands (Hornschemeier et al. 2001, Alexander et al. 2001, Fiore et al. 2003, Della Ceca et al. 2004, Cocchia et al. 2007).”
The HELLAS2XMM Survey. II. Multiwavelength Observations of P3: An X-Ray-bright, Optically Inactive Galaxy (2002, background): “…line objects and, even more surprisingly, some 50% of the spectroscopically identified sources do not show obvious signatures of AGN activity in their optical spectra, which are instead typical of early-type “normal” galaxies (Hornschemeier et al. 2001; Giacconi et al. 2001; Barger et al. 2001).”
