Testable likelihoods for beyond-the-standard model fits (2023)
Journal Article
Beck, A., Reboud, M., & van Dyk, D. (2023). Testable likelihoods for beyond-the-standard model fits. The European Physical Journal C, 83(12), Article 1115. https://doi.org/10.1140/epjc/s10052-023-12294-0

Studying potential BSM effects at the precision frontier requires accurate transfer of information from low-energy measurements to high-energy BSM models. We propose to use normalising flows to construct likelihood functions that achieve this transfe... Read More about Testable likelihoods for beyond-the-standard model fits.

FLASH: Faint Lenses from Associated Selection with Herschel (2023)
Journal Article
Bakx, T. J. L. C., Gray, B. S., González-Nuevo, J., Bonavera, L., Amvrosiadis, A., Eales, S., …Serjeant, S. (2023). FLASH: Faint Lenses from Associated Selection with Herschel. Monthly Notices of the Royal Astronomical Society, 527(3), 8865-8885. https://doi.org/10.1093/mnras/stad3759

We report the ALMA Band 7 observations of 86 Herschel sources that likely contain gravitationally lensed galaxies. These sources are selected with relatively faint 500 μm flux densities between 15 and 85 mJy in an effort to characterize the effect of...

FeynMG: A FeynRules extension for scalar-tensor theories of gravity (2023)
Journal Article
Sevillano Muñoz, S., Copeland, E. J., Millington, P., & Spannowsky, M. (2024). FeynMG: A FeynRules extension for scalar-tensor theories of gravity. Computer Physics Communications, 296, Article 109035. https://doi.org/10.1016/j.cpc.2023.109035

The ability to represent perturbative expansions of interacting quantum field theories in terms of simple diagrammatic rules has revolutionized calculations in particle physics (and elsewhere). Moreover, these rules are readily automated, a process t... Read More about FeynMG: A FeynRules extension for scalar-tensor theories of gravity.

DESI mock challenge: constructing DESI galaxy catalogues based on FastPM simulations (2023)
Journal Article
Variu, A., Alam, S., Zhao, C., Chuang, C., Yu, Y., Forero-Sánchez, D., …Zhou, Z. (2024). DESI mock challenge: constructing DESI galaxy catalogues based on FastPM simulations. Monthly Notices of the Royal Astronomical Society, 527(4), 11539-11558. https://doi.org/10.1093/mnras/stad3742

Together with larger spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI), the precision of large scale structure studies and thus the constraints on the cosmological parameters are rapidly improving. Therefore, one must buil... Read More about DESI mock challenge: constructing DESI galaxy catalogues based on FastPM simulations.

Scanning for dark matter subhaloes in Hubble Space Telescope imaging of 54 strong lenses (2023)
Journal Article
Nightingale, J. W., He, Q., Cao, X., Amvrosiadis, A., Etherington, A., Frenk, C. S., Hayes, R. G., Robertson, A., Cole, S., Lange, S., Li, R., & Massey, R. (2024). Scanning for dark matter subhaloes in Hubble Space Telescope imaging of 54 strong lenses. Monthly Notices of the Royal Astronomical Society, 527(4), 10480-10506. https://doi.org/10.1093/mnras/stad3694

The cold dark matter (DM) model predicts that every galaxy contains thousands of DM subhaloes; almost all other DM models include a physical process that smooths away the subhaloes. The subhaloes are invisible, but could be detected via strong gravit... Read More about Scanning for dark matter subhaloes in Hubble Space Telescope imaging of 54 strong lenses.

Testing high scale supersymmetry via second order gravitational waves (2023)
Journal Article
Flores, M. M., Kusenko, A., Pearce, L., Perez-Gonzalez, Y. F., & White, G. (2023). Testing high scale supersymmetry via second order gravitational waves. Physical Review D, 108, Article 123002. https://doi.org/10.1103/PhysRevD.108.123002

Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton number. Condensates in such directions form during inflation and later fragment into Q balls, which can become the building blocks of primordial black holes....

Tuning magnon spectra via interlayer coupling in pseudo-3D nanostructured artificial spin ice arrays (2023)
Journal Article
de Rojas, J., Atkinson, D., & Adeyeye, A. O. (2023). Tuning magnon spectra via interlayer coupling in pseudo-3D nanostructured artificial spin ice arrays. Applied Physics Letters, 123(23), Article 232407. https://doi.org/10.1063/5.0177447

We have investigated the static and dynamic behavior of “pseudo-3D” trilayer square artificial spin ice structures. The trilayer stack comprises of two ferromagnetic Ni81Fe19 (Permalloy, Py) layers with 30 and 70 nm thickness, separated by a nonmagne...

Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power (2023)
Journal Article
Broggio, A., Jaskiewicz, S., & Vernazza, L. (2023). Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power. Journal of High Energy Physics, 2023(12), Article 28. https://doi.org/10.1007/jhep12%282023%29028

We present a factorization theorem of the partonic Drell-Yan off-diagonal processes gq¯qg→γ∗+X in the kinematic threshold regime z=Q2/ŝ→1 at general subleading powers in the (1 − z) expansion. Focusing on the first order of the expansion (next-to-le... Read More about Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power.
