Detection of Time Lags between Quasar Continuum Emission Bands Based On Pan-STARRS Light Curves (2017)
Journal Article
Jiang, Y., Green, P., Greene, J., Morganson, E., Shen, Y., Pancoast, A., …Waters, C. (2017). Detection of Time Lags between Quasar Continuum Emission Bands Based On Pan-STARRS Light Curves. Astrophysical Journal, 836(2), Article 186. https://doi.org/10.3847/1538-4357/aa5b91

As photons from different bands emerge from different radial ranges in the accretion disk, the lags constrain the sizes of the accretion disks. We select 240 quasars with redshifts of z ≈ 1 or z ≈ 0.3 that are relatively emission-line free. The light...

Identification of partially resolved binaries in Pan-STARRS 1 data (2017)
Journal Article
Deacon, N., Magnier, E., Best, W., Liu, M., Dupuy, T., Chambers, K., …Waters, C. (2017). Identification of partially resolved binaries in Pan-STARRS 1 data. Monthly Notices of the Royal Astronomical Society, 468(3), 3499-3515. https://doi.org/10.1093/mnras/stx440

Using shape measurement techniques developed for weak lensing surveys, we have identified three new ultracool binaries in the Pan-STARRS 1 (Chambers et al.) survey. Binary companions that are not completely resolved can still alter the shapes of stel... Read More about Identification of partially resolved binaries in Pan-STARRS 1 data.

We present the discovery of a 360 au separation T3 companion to the tight (3.1 au) M4.5+M6.5 binary 2MASS J02132062+3648506. This companion was identified using Pan-STARRS 1 data and despite its relative proximity to the Sun (22.2 +6.4−4.0 −4.0+6.4 p...

We present a systematic search for periodically varying quasars and supermassive black hole binary (SMBHB) candidates in the Pan-STARRS1 (PS1) Medium Deep Survey's MD09 field. From a color-selected sample of 670 quasars extracted from a multi-band de...

Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores (2016)
Journal Article
Green, T., Edge, A., Ebeling, H., Burgett, W., Draper, P., Kaiser, N., …Waters, C. (2017). Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores. Monthly Notices of the Royal Astronomical Society, 465(4), 4872-4885. https://doi.org/10.1093/mnras/stw3059

A key challenge in understanding the feedback mechanism of active galactic nucleus (AGN) in Brightest Cluster Galaxies (BCGs) is the inherent rarity of catching an AGN during its strong outburst phase. This is exacerbated by the ambiguity of differen... Read More about Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores.

The Pan-STARRS1 Distant z > 5.6 Quasar Survey: More than 100 Quasars within the First Gyr of the Universe (2016)
Journal Article
Bañados, E., Venemans, B., Decarli, R., Farina, E., Mazzucchelli, C., Walter, F., …Yang, Q. (2016). The Pan-STARRS1 Distant z > 5.6 Quasar Survey: More than 100 Quasars within the First Gyr of the Universe. Astrophysical Journal Supplement, 227(1), Article 11. https://doi.org/10.3847/0067-0049/227/1/11

Luminous quasars at $z\gt 5.6$ can be studied in detail with the current generation of telescopes and provide us with unique information on the first gigayear of the universe. Thus far, these studies have been statistically limited by the number of q...

We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift z = 0.5215 discovered in the last months of the Pan-STARRS1 Medium Deep Survey. PS1-14bj stands out because of its extremely slow evolution... Read More about PS1-14bj: A Hydrogen-poor Superluminous Supernova With a Long Rise and Slow Decay.
