The stellar mass content of submillimeter-selected galaxies (2011)
Journal Article
Hainline, L., Blain, A., Smail, I., Alexander, D., Armus, L., Chapman, S., & Ivison, R. (2011). The stellar mass content of submillimeter-selected galaxies. Astrophysical Journal, 740(2), Article 96. https://doi.org/10.1088/0004-637x/740/2/96

We present a new study of stellar mass in a sample of ~70 submillimeter-selected galaxies (SMGs) with accurate spectroscopic redshifts. We fit combinations of stellar population synthesis models and power laws to the galaxies' observed-frame optical... Read More about The stellar mass content of submillimeter-selected galaxies.

Revealing a Population of Heavily Obscured Active Galactic Nuclei at z ≈ 0.5-1 in the Chandra Deep Field-South (2011)
Journal Article
Luo, B., Brandt, W., Xue, Y., Alexander, D., Brusa, M., Bauer, F., …Vignali, C. (2011). Revealing a Population of Heavily Obscured Active Galactic Nuclei at z ≈ 0.5-1 in the Chandra Deep Field-South. Astrophysical Journal, 740(1), Article 37. https://doi.org/10.1088/0004-637x/740/1/37

Heavily obscured (N H >~ 3 × 1023 cm-2) active galactic nuclei (AGNs) not detected even in the deepest X-ray surveys are often considered to be comparably numerous to the unobscured and moderately obscured AGNs. Such sources are required to fit the c... Read More about Revealing a Population of Heavily Obscured Active Galactic Nuclei at z ≈ 0.5-1 in the Chandra Deep Field-South.

NICMOS Polarimetry of ''Polar-scattered'' Seyfert 1 Galaxies (2011)
Journal Article
Batcheldor, D., Robinson, A., Axon, D., Young, S., Quinn, S., Smith, J., …Alexander, D. (2011). NICMOS Polarimetry of ''Polar-scattered'' Seyfert 1 Galaxies. Astrophysical Journal, 738(1), Article 90. https://doi.org/10.1088/0004-637x/738/1/90

The nuclei of Seyfert 1 galaxies exhibit a range of optical polarization characteristics that can be understood in terms of two scattering regions producing orthogonal polarizations: an extended polar scattering region (PSR) and a compact equatorial...

A New Diagnostic of Active Galactic Nuclei: Revealing Highly Absorbed Systems at Redshift >0.3 (2011)
Journal Article
Juneau, S., Dickinson, M., Alexander, D., & Salim, S. (2011). A New Diagnostic of Active Galactic Nuclei: Revealing Highly Absorbed Systems at Redshift >0.3. Astrophysical Journal, 736(2), Article 104. https://doi.org/10.1088/0004-637x/736/2/104

We introduce the Mass-Excitation (MEx) diagnostic to identify active galactic nuclei (AGNs) in galaxies at intermediate redshift. In the absence of near-infrared spectroscopy, necessary for using traditional nebular line diagrams at z > 0.4, we demon...

The LABOCA survey of the Extended Chandra Deep Field-South : a photometric redshift survey of submillimetre galaxies (2011)
Journal Article
Wardlow, J., Smail, I., Coppin, K., Alexander, D., Brandt, W., Danielson, A., …van der Werf, P. (2011). The LABOCA survey of the Extended Chandra Deep Field-South : a photometric redshift survey of submillimetre galaxies. Monthly Notices of the Royal Astronomical Society, 415(2), 1479-1508. https://doi.org/10.1111/j.1365-2966.2011.18795.x

We derive photometric redshifts from 17-band optical to mid-infrared photometry of 78 robust radio, 24-μm and Spitzer IRAC counterparts to 72 of the 126 submillimetre galaxies (SMGs) selected at 870 μm by LABOCA observations in the Extended Chandra D...
