High-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies selected from the UKIDSS Ultra Deep Survey at z > 1, we perform a stacking a...

Increasing AGN sample completeness using long-term near-infrared variability (2024)
Journal Article
Green, K., Elmer, E., Maltby, D. T., Almaini, O., Merrifield, M., & Hartley, W. G. (2024). Increasing AGN sample completeness using long-term near-infrared variability. Monthly Notices of the Royal Astronomical Society, 531(2), 2551-2562. https://doi.org/10.1093/mnras/stae1322

In this work, we use 8 years of deep near-infrared imaging to select and study a new set of 601 active galaxies identified through long-term near-infrared (NIR) variability in the UKIDSS Ultra Deep Survey (UDS). These objects are compared to 710 X-ra... Read More about Increasing AGN sample completeness using long-term near-infrared variability.
