Mid-infrared spectroscopy of candidate active galactic nuclei-dominated submillimeter galaxies (2010)
Journal Article
Coppin, K., Pope, A., Menéndez-Delmestre, K., Alexander, D., Dunlop, J., Egami, E., …Yun, M. (2010). Mid-infrared spectroscopy of candidate active galactic nuclei-dominated submillimeter galaxies. Astrophysical Journal, 713(1), 503-519. https://doi.org/10.1088/0004-637x/713/1/503

Spitzer spectroscopy has revealed that sime80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining sime20% that show signs of harboring powerful active galactic nuclei (AGNs). We have obtained Spi...

Journal Article
Lutz, D., Mainieri, V., Rafferty, D., Shao, L., Hasinger, G., Weiß, A., …Xue, Y. (2010). The LABOCA survey of the extended Chandra Deep Field South : two modes of star formation in active galactic nucleus hosts?. Astrophysical Journal, 712(2), 1287-1301. https://doi.org/10.1088/0004-637x/712/2/1287

We study the co-existence of star formation and active galactic nucleus (AGN) activity in Chandra X-ray-selected AGN by analyzing stacked 870 μm submillimeter emission from a deep and wide map of the Extended Chandra Deep Field South (ECDFS), obtaine...

X-ray constraints on the active galactic nuclei properties in Spitzer-infrared spectrograph identified z ~ 2 ultraluminous infrared galaxies (2010)
Journal Article
Bauer, F., Yan, L., Sajina, A., & Alexander, D. (2010). X-ray constraints on the active galactic nuclei properties in Spitzer-infrared spectrograph identified z ~ 2 ultraluminous infrared galaxies. Astrophysical Journal, 710(1), 212-226. https://doi.org/10.1088/0004-637x/710/1/212

We report Chandra X-ray constraints for 20 of the 52 high-redshift ultraluminous infrared galaxies (ULIRGs) identified in the Spitzer Extragalactic First Look Survey with f ν(24 μm)>0.9 mJy, log ({ν f_{ν}(24 μm)\over ν f_{ν}(R)})>1, and log ({ν f_{ν...
