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...

We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint (mR = 27.5 mag, zph ∼ 2.2) host in the CANDELS survey. The X-ray event is comprised of 115 +12−11 −11+12... Read More about A new, faint population of X-ray transients.

We present an analysis of the mid-infrared Wide-field Infrared Survey Explorer (WISE) sources seen within the equatorial GAMA G12 field, located in the North Galactic Cap. Our motivation is to study and characterize the behavior of WISE source popula... Read More about Galaxy and Mass Assembly (GAMA): Exploring the WISE Web in G12.

A measurement of the z = 0 UV background from Halpha fluorescence (2017)

We report the detection of extended Halpha emission from the tip of the HI disk of the nearby edge-on galaxy UGC 7321, observed with the Multi Unit Spectroscopic Explorer (MUSE) instrument at the Very Large Telescope. The Halpha surface brightness fa... Read More about A measurement of the z = 0 UV background from Halpha fluorescence.

Next-to-Next-to Leading Order QCD Predictions for Single Jet Inclusive Production at the LHC (2017)

We report the first calculation of fully differential jet production at leading color in all partonic channels at next-to-next-to leading order in perturbative QCD and compare to the available ATLAS 7 TeV data. We discuss the size and shape of the pe... Read More about Next-to-Next-to Leading Order QCD Predictions for Single Jet Inclusive Production at the LHC.

A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR (2017)
Journal Article

NGC 1448 is one of the nearest luminous galaxies (L8−1000μm> 109L⊙) to ours (z = 0.00390), and yet the active galactic nucleus (AGN) it hosts was only recently discovered, in 2009. In this paper, we present an analysis of the nuclear source across th... Read More about A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR.

Identification of partially resolved binaries in Pan-STARRS 1 data (2017)
Journal Article

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.

Weak lensing by galaxy troughs with modified gravity (2017)
Journal Article

We study the imprints that theories of gravity beyond GR can leave on the lensing signal around line of sight directions that are predominantly halo-underdense (called troughs) and halo-overdense. To carry out our investigations, we consider the norm... Read More about Weak lensing by galaxy troughs with modified gravity.

We compare four- and five-flavor scheme predictions for b-associated production of Z and Higgs bosons. The results are obtained with SHERPA ’s MC@NLO implementation for the four-flavor scheme, treating the b’s as massive, and with multijet merging at...
