On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo (2023)
Journal Article
Bianconi, M., Smith, G. P., Nicholl, M., Ryczanowski, D., Richard, J., Jauzac, M., Massey, R., Robertson, A., Sharon, K., & Ridley, E. (2023). On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo. Monthly Notices of the Royal Astronomical Society, 521(3), 3421-3430. https://doi.org/10.1093/mnras/stad673

We search for gravitational wave (GW) events from LIGO-Virgo’s third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and alters their amplitude – thus biasing the inferred progenitor masses....

Modelling gas around galaxy pairs and groups using the Q0107 quasar triplet (2023)
Journal Article
Beckett, A., Morris, S. L., Fumagalli, M., Tejos, N., Jannuzi, B., & Cantalupo, S. (2023). Modelling gas around galaxy pairs and groups using the Q0107 quasar triplet. Monthly Notices of the Royal Astronomical Society, 521(1), 1113-1143. https://doi.org/10.1093/mnras/stad596

We examine to what extent disc and outflow models can reproduce observations of H I gas within a few virial radii of galaxies in pairs and groups. Using highly sensitive HST/COS and FOS spectra of the Q0107 quasar triplet covering Ly α for z≲1, as we...

High energy resummed predictions for the production of a Higgs boson with at least one jet (2023)
Journal Article
Andersen, J. R., Hassan, H., Maier, A., Paltrinieri, J., Papaefstathiou, A., & Smillie, J. M. (2023). High energy resummed predictions for the production of a Higgs boson with at least one jet. Journal of High Energy Physics, 2023(3), Article 1 (2023). https://doi.org/10.1007/jhep03%282023%29001

We present all-order predictions for Higgs boson production plus at least one jet which are accurate to leading logarithm in s^/|p⊥|2. Our calculation includes full top and bottom quark mass dependence at all orders in the logarithmic part, and to hi...

A Complex Dust Morphology in the High-luminosity AGN Mrk 876 (2023)
Journal Article
Landt, H., Mitchell, J. A., Ward, M. J., Mercatoris, P., Pott, J.-U., Horne, K., Hernández Santisteban, J. V., Malhotra, D., Cackett, E. M., Goad, M. R., Romero Colmenero, E., & Winkler, H. (2023). A Complex Dust Morphology in the High-luminosity AGN Mrk 876. Astrophysical Journal, 945(1), Article 62. https://doi.org/10.3847/1538-4357/acb92d

Recent models for the inner structures of active galactic nuclei (AGNs) advocate the presence of a radiatively accelerated dusty outflow launched from the outer regions of the accretion disk. Here, we present the first near-IR variable (rms) spectrum... Read More about A Complex Dust Morphology in the High-luminosity AGN Mrk 876.

Precision Modeling of JWST's First Cluster Lens SMACS J0723.3–7327* (2023)
Journal Article
Mahler, G., Jauzac, M., Richard, J., Beauchesne, B., Ebeling, H., Lagattuta, D., Natarajan, P., Sharon, K., Atek, H., Claeyssens, A., Clément, B., Eckert, D., Edge, A., Kneib, J.-P., & Niemiec, A. (2023). Precision Modeling of JWST's First Cluster Lens SMACS J0723.3–7327*. Astrophysical Journal, 945(1), Article 49. https://doi.org/10.3847/1538-4357/acaea9

Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens model for the massive galaxy cluster SMACS J0723.3−7323 (SMACS J0723; z = 0.388) that significantly improves upon earlier work. Building on strong-lensing cons... Read More about Precision Modeling of JWST's First Cluster Lens SMACS J0723.3–7327*.

The hyperluminous X‐ray source population (2023)
Journal Article
MacKenzie, A., Roberts, T., & Walton, D. (2023). The hyperluminous X‐ray source population. Astronomische Nachrichten, 344(4), Article e230028. https://doi.org/10.1002/asna.20230028

We have recently published a catalog of 1843 candidate ultraluminous X-ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross-correlating recent serendipitous source catalogs from the XMM-Newton, Swift, and Chandra obs...

Nanoscale probing of local dielectric changes at the interface between solids and aqueous saline solutions (2023)
Journal Article
Trewby, W., & Voïtchovsky, K. (2023). Nanoscale probing of local dielectric changes at the interface between solids and aqueous saline solutions. Faraday Discussions, 246, 387-406. https://doi.org/10.1039/d3fd00021d

The mobility of dissolved ions and charged molecules at interfaces underpins countless processes in science and technology. Experimentally, this is typically measured from the averaged response of the charges to an electrical potential. High-resoluti...

A new method for age-dating the formation of bars in disc galaxies (2023)
Journal Article

The epoch in which galactic discs settle is a major benchmark for testing models of galaxy formation and evolution but remains largely unknown. Once discs settle and become sufficiently self-gravitating, stellar bars are able to form; therefore, dete... Read More about A new method for age-dating the formation of bars in disc galaxies.

NP-hard but no longer hard to solve? Using quantum computing to tackle optimization problems (2023)
Journal Article

In the last decade, public and industrial research funding has moved quantum computing from the early promises of Shor’s algorithm through experiments to the era of noisy intermediate scale quantum devices (NISQ) for solving real-world problems. It i... Read More about NP-hard but no longer hard to solve? Using quantum computing to tackle optimization problems.
