The Properties and Redshift Evolution of Intermediate-Luminosity Off-Nuclear X-Ray Sources in the Chandra Deep Fields (2007)
Journal Article
Lehmer, B., Brandt, W., Hornschemeier, A., Alexander, D., Bauer, F., Koekemoer, A., …Steffen, A. (2007). The Properties and Redshift Evolution of Intermediate-Luminosity Off-Nuclear X-Ray Sources in the Chandra Deep Fields. Astronomical Journal, 131(5), 2394-2405. https://doi.org/10.1086/503107

We analyze a population of intermediate-redshift (z~0.05-0.3) off-nuclear X-ray sources located within optically bright galaxies in the Great Observatories Origins Deep Survey and Galaxy Evolution from Morphology and SEDs fields. A total of 24 off-nu... Read More about The Properties and Redshift Evolution of Intermediate-Luminosity Off-Nuclear X-Ray Sources in the Chandra Deep Fields.

X-Ray Properties of Lyman Break Galaxies in the Great Observatories Origins Deep Survey (2007)
Journal Article
Lehmer, B., Brandt, W., Alexander, D., Bauer, F., Conselice, C., Dickinson, M., …Schneider, D. (2007). X-Ray Properties of Lyman Break Galaxies in the Great Observatories Origins Deep Survey. Astronomical Journal, 129(1), 1-8. https://doi.org/10.1086/426335

We constrain the X-ray emission properties of Lyman break galaxies (LBGs) at z 3–6 using the 2 Ms Chandra Deep Field North and 1 Ms Chandra Deep Field South. Large samples of LBGs were discovered using the Hubble Space Telescope as part of the Great...

The X-Ray Evolution of Early-Type Galaxies in the Extended Chandra Deep Field-South (2007)
Journal Article
Lehmer, B., Brandt, W., Alexander, D., Bell, E., McIntosh, D., Bauer, F., …Steffen, A. (2007). The X-Ray Evolution of Early-Type Galaxies in the Extended Chandra Deep Field-South. Astrophysical Journal, 657(1), 681-699. https://doi.org/10.1086/511297

We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since ) of the average X‐ray properties of early‐type galaxies within the Extended Chandra Deep Field–South (E‐CDF‐S). Our early‐type galaxy sample includes 539 objects with red... Read More about The X-Ray Evolution of Early-Type Galaxies in the Extended Chandra Deep Field-South.
