Next-to-leading order QCD corrections to diphoton-plus-jet production through gluon fusion at the LHC (2021)
Journal Article
Badger, S., Gehrmann, T., Marcoli, M., & Moodie, R. (2022). Next-to-leading order QCD corrections to diphoton-plus-jet production through gluon fusion at the LHC. Physics Letters B, 824, Article 136802. https://doi.org/10.1016/j.physletb.2021.136802

We compute the next-to-leading order (NLO) QCD corrections to the gluon-fusion subprocess of diphoton-plus-jet production at the LHC. We compute fully differential distributions by combining two-loop virtual corrections with one-loop real radiation u...

Updated detection prospects for relic neutrinos using coherent scattering (2021)
Journal Article
Shergold, J. D. (2021). Updated detection prospects for relic neutrinos using coherent scattering. Journal of Cosmology and Astroparticle Physics, 2021(11), Article 052. https://doi.org/10.1088/1475-7516/2021/11/052

We review the existing proposals to detect relic neutrinos using the coherent scattering of a neutrino wind on a test mass. By considering the transformation of the neutrino momentum between reference frames, we demonstrate that the induced accelerat...

We introduce the ABACUSHOD model and present two applications of ABACUSHOD and the ABACUSSUMMIT simulations to observations. ABACUSHOD is a Halo Occupation Distribution (HOD) framework written in PYTHON that is particle-based, multitracer, highly gen...

I describe and demonstrate a new approach to using spectroscopic data to exploit Poisson sampling fluctuations in unresolved stellar populations. The method is introduced using spectra predicted for independent samples of stars from a 10 Gyr populati...

Monthly Notices of the Royal Astronomical Society, 509(4), 6111-6118. https://doi.org/10.1093/mnras/stab3399

Ground-based photometry of bright stars is expected to be limited by atmospheric scintillation, although in practice observations are often limited by other sources of systematic noise. We analyse 122 nights of bright star (Gmag ≲ 11.5) photometry us... Read More about Scintillation-limited photometry with the 20-cm NGTS telescopes at Paranal Observatory.

Astrophysical Journal, 922(2), Article 151. https://doi.org/10.3847/1538-4357/ac2159

We present the first results from the ongoing, intensive, multiwavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this active galactic nucleus was, in part, selected for its historically unobscured nature, we discovered tha... Read More about AGN STORM 2. I.

Making use of sub-resolution haloes in N-body simulations (2021)
Journal Article
Armijo, J., Baugh, C. M., Padilla, N. D., Norberg, P., & Arnold, C. (2022). Making use of sub-resolution haloes in N-body simulations. Monthly Notices of the Royal Astronomical Society, 510(1), 29-33. https://doi.org/10.1093/mnrasl/slab122

Conservative mass limits are often imposed on the dark matter halo catalogues extracted from N-body simulations. By comparing simulations with different mass resolutions, at z = 0 we find that even for haloes resolved by 100 particles, the lower reso...

Shortly after its discovery, General Relativity (GR) was applied to predict the behavior of our Universe on the largest scales, and later became the foundation of modern cosmology. Its validity has been verified on a range of scales and environments...

We present a Spitzer/IRAC survey of H-faint (H160 ≳ 26.4, < 5σ) sources in 101 lensing cluster fields. Across a CANDELS/Wide-like survey area of ∼648 arcmin2 (effectively ∼221 arcmin2 in the source plane), we have securely discovered 53 sources in th...
