Cresting the wave: proper motions of the Eastern Banded Structure (2017)
Journal Article
Deason, A., Belokurov, V., & Koposo, V. S. (2018). Cresting the wave: proper motions of the Eastern Banded Structure. Monthly Notices of the Royal Astronomical Society, 473(2), 2428-2433. https://doi.org/10.1093/mnras/stx2528

We study the kinematic properties of the Eastern Banded Structure (EBS) and Hydra I overdensity using exquisite proper motions derived from the Sloan Digital Sky Survey (SDSS) and Gaia source catalogue. Main sequence turn-off stars in the vicinity of... Read More about Cresting the wave: proper motions of the Eastern Banded Structure.

Space Telescope and Optical Reverberation Mapping Project. VII. Understanding the Ultraviolet Anomaly in NGC 5548 with X-Ray Spectroscopy (2017)
Journal Article
Mathur, S., Gupta, A., Page, K., Pogge, R., Krongold, Y., Goad, M., …Zu, Y. (2017). Space Telescope and Optical Reverberation Mapping Project. VII. Understanding the Ultraviolet Anomaly in NGC 5548 with X-Ray Spectroscopy. Astrophysical Journal, 846(1), Article 55. https://doi.org/10.3847/1538-4357/aa832b

During the Space Telescope and Optical Reverberation Mapping Project observations of NGC 5548, the continuum and emission-line variability became decorrelated during the second half of the six-month-long observing campaign. Here we present Swift and... Read More about Space Telescope and Optical Reverberation Mapping Project. VII. Understanding the Ultraviolet Anomaly in NGC 5548 with X-Ray Spectroscopy.

The slight spin of the old stellar halo (2017)
Journal Article
Deason, A. J., Belokurov, V., Koposov, S. E., Gómez, F. A., Grand, R. J., Marinacci, F., & Pakmor, R. (2017). The slight spin of the old stellar halo. Monthly Notices of the Royal Astronomical Society, 470(2), 1259-1273. https://doi.org/10.1093/mnras/stx1301

We combine Gaia data release 1 astrometry with Sloan Digital Sky Survey (SDSS) images taken some ∼10–15 years earlier, to measure proper motions of stars in the halo of our Galaxy. The SDSS–Gaia proper motions have typical statistical errors of 2 mas... Read More about The slight spin of the old stellar halo.

Space Telescope and Optical Reverberation Mapping Project. V. Optical Spectroscopic Campaign and Emission-line Analysis for NGC 5548 (2017)
Journal Article
Pei, L., Fausnaugh, M., Barth, A., Peterson, B., Bentz, M., De Rosa, G., …Zu, Y. (2017). Space Telescope and Optical Reverberation Mapping Project. V. Optical Spectroscopic Campaign and Emission-line Analysis for NGC 5548. Astrophysical Journal, 837(2), Article 131. https://doi.org/10.3847/1538-4357/aa5eb1

We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned six months and achieved an almost daily cadence with observations from... Read More about Space Telescope and Optical Reverberation Mapping Project. V.

The Clouds are breaking: tracing the Magellanic system with Gaia DR1 Mira variables (2017)
Journal Article
Deason, A., Belokurov, V., Erkal, D., Koposov, S., & Mackey, D. (2017). The Clouds are breaking: tracing the Magellanic system with Gaia DR1 Mira variables. Monthly Notices of the Royal Astronomical Society, 467(3), 2636-2647. https://doi.org/10.1093/mnras/stx263

We exploit the first data release from the Gaia mission to identify candidate Mira variables in the outskirts of the Magellanic Clouds. The repeated observations of sources during the initial phase of the Gaia mission is used to identify stars that s...
