Journal Article
Pagul, A., Sánchez, F. J., Davidzon, I., Koekemoer, A. M., Mobasher, B., Jauzac, M., Steinhardt, C. L., Atek, H., Cen, R., Chemerynska, I., Furtak, L. J., Lagattuta, D. J., Mahler, G., Montes, M., Nonino, M., Sharon, K., & Weaver, J. R. (2024). Self-consistent Combined HST, K -band, and Spitzer Photometric Catalogs of the BUFFALO Survey Fields. Astrophysical Journal Supplement, 273(1), Article 10. https://doi.org/10.3847/1538-4365/ad40a1

This article presents new astronomical source catalogs using data from the BUFFALO Survey. These catalogs contain detailed information for over 100,000 astronomical sources in the six BUFFALO clusters: A370, A2744, AS1063, MACS 0416, MACS 0717, and M...

Strong gravitational lensing’s ‘external shear’ is not shear (2024)
Journal Article
Etherington, A., Nightingale, J., Massey, R., Tam, S.-I., Cao, X., Niemiec, A., He, Q., Robertson, A., Li, R., Amvrosiadis, A., Cole, S., Diego, J., Frenk, C., Frye, B., Harvey, D., Jauzac, M., Koekemoer, A., Lagattuta, D., Lange, S., Limousin, M., …Steinhardt, C. (2024). Strong gravitational lensing’s ‘external shear’ is not shear. Monthly Notices of the Royal Astronomical Society, 531(3), 3684-3697. https://doi.org/10.1093/mnras/stae1375

The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power-law plus ‘external shear’, which notionally accounts for neighbouring galaxies and cosmic shear along our line of sight. A small amount of e... Read More about Strong gravitational lensing’s ‘external shear’ is not shear.

BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1 (2024)
Journal Article
Diego, J. M., Li, S. K., Meena, A. K., Niemiec, A., Acebron, A., Jauzac, M., …Pascale, M. (2024). BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1. Astronomy & Astrophysics, 681, Article A124. https://doi.org/10.1051/0004-6361/202346761

In this work, we present a constraint on the abundance of supergiant (SG) stars at redshift z ≈ 1, based on recent observations of a strongly lensed arc at this redshift. First we derived a free-form model of MACS J0416.1-2403 using data from the Be...

A full reconstruction of two galaxy clusters intra-cluster medium with strong gravitational lensing (2024)
Journal Article
Allingham, J. F. V., Bœhm, C., Eckert, D., Jauzac, M., Lagattuta, D., Mahler, G., …Ettori, S. (2024). A full reconstruction of two galaxy clusters intra-cluster medium with strong gravitational lensing. Monthly Notices of the Royal Astronomical Society, 528(2), 1711-1736. https://doi.org/10.1093/mnras/stae107

Whilst X-rays and Sunyaev–Zel’dovich observations allow to study the properties of the intra-cluster medium (ICM) of galaxy clusters, their gravitational potential may be constrained using strong gravitational lensing. Although being physically relat... Read More about A full reconstruction of two galaxy clusters intra-cluster medium with strong gravitational lensing.
