Journal Article
Jin, C., Done, C., & Ward, M. (2021). Re-observing the NLS1 galaxy RE J1034+396 – II. New insights on the soft X-ray excess, QPO, and the analogy with GRS 1915+105. Monthly Notices of the Royal Astronomical Society, 500(2), 2475-2495. https://doi.org/10.1093/mnras/staa3386

The active galactic nucleus (AGN) RE J1034+396 displays the most significant X-ray quasi-periodic oscillation (QPO) detected so far. We perform a detailed spectral-timing analysis of our recent simultaneous XMM–Newton, NuSTAR, and Swift observations.... Read More about Re-observing the NLS1 galaxy RE J1034+396 – II.

The evolution of gas-phase metallicity and resolved abundances in star-forming galaxies at z ≍ 0.6-1.8 (2020)
Journal Article
Gillman, S., Tiley, A., Swinbank, A., Dudzevičiūtė, U., Sharples, R., Smail, I., …Stott, J. P. (2021). The evolution of gas-phase metallicity and resolved abundances in star-forming galaxies at z ≍ 0.6-1.8. Monthly Notices of the Royal Astronomical Society, 500(3), 4229-4247. https://doi.org/10.1093/mnras/staa3400

We present an analysis of the chemical abundance properties of ≈650 star-forming galaxies at z ≈ 0.6–1.8. Using integral-field observations from the K-band multi-object spectrograph (KMOS), we quantify the [N II]/H α emission-line ratio, a proxy for...

The Pan-STARRS1 (PS1) Science Consortium has carried out a set of imaging surveys using the 1.4 gigapixel GPC1 camera on the PS1 telescope. As this camera is composed of many individual electronic readouts and covers a very large field of view, great... Read More about Pan-STARRS Pixel Processing: Detrending, Warping, Stacking.

Pan-STARRS Photometric and Astrometric Calibration (2020)
Journal Article
Magnier, E. A., Schlafly, E. F., Finkbeiner, D. P., Tonry, J., Goldman, B., Röser, S., …Wainscoat, R. (2020). Pan-STARRS Photometric and Astrometric Calibration. Astrophysical Journal Supplement, 251(1), Article 6. https://doi.org/10.3847/1538-4365/abb82a

We present the details of the photometric and astrometric calibration of the Pan-STARRS1 3π Survey. The photometric goals were to reduce the systematic effects introduced by the camera and detectors, and to place all of the observations onto a photom...

A Positive Resampler for Monte Carlo events with negative weights (2020)
Journal Article
Andersen, J. R., Gütschow, C., Maier, A., & Prestel, S. (2020). A Positive Resampler for Monte Carlo events with negative weights. The European Physical Journal C, 80(11), Article 1007. https://doi.org/10.1140/epjc/s10052-020-08548-w

We propose the Positive Resampler to solve the problem associated with event samples from state-of-the-art predictions for scattering processes at hadron colliders typically involving a sizeable number of events contributing with negative weight. The... Read More about A Positive Resampler for Monte Carlo events with negative weights.

Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae (2020)
Journal Article
Turnbull, L. A., Birch, M. T., Laurenson, A., Bukin, N., Burgos-Parra, E. O., Popescu, H., …Hatton, P. D. (2021). Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae. ACS Nano, 15(1), 387-395. https://doi.org/10.1021/acsnano.0c07392

Nanoscopic lamellae of centrosymmetric ferromagnetic alloys have recently been reported to host the biskyrmion spin texture; however, this has been disputed as the misidentication of topologically trivial type-II magnetic bubbles. Here we demonstrate... Read More about Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae.
