Revealing galaxy candidates out to z ∼ 16 with JWST observations of the lensing cluster SMACS0723 (2022)
Journal Article
Atek, H., Shuntov, M., Furtak, L. J., Richard, J., Kneib, J.-P., Mahler, G., Zitrin, A., McCracken, H., Charlot, S., Chevallard, J., & Chemerynska, I. (2023). Revealing galaxy candidates out to z ∼ 16 with JWST observations of the lensing cluster SMACS0723. Monthly Notices of the Royal Astronomical Society, 519(1), 1201 - 1220. https://doi.org/10.1093/mnras/stac3144

One of the main goals of the JWST is to study the first galaxies in the Universe. We present a systematic photometric analysis of very distant galaxies in the first JWST deep field towards the massive lensing cluster SMACS0723. As a result, we report...

Gravitational lensing effects of supermassive black holes in cluster environments (2022)
Journal Article
Mahler, G., Natarajan, P., Jauzac, M., & Richard, J. (2023). Gravitational lensing effects of supermassive black holes in cluster environments. Monthly Notices of the Royal Astronomical Society, 518(1), 54-65. https://doi.org/10.1093/mnras/stac3098

This study explores the gravitational lensing effects of supermassive black holes (SMBHs) in galaxy clusters. While the presence of central SMBHs in galaxies is firmly established, recent work from high-resolution simulations predict the existence of...

Ages of Quiescent Member Galaxies at 0.3 < z < 1.4. Astrophysical Journal, 934(2), https://doi.org/10.3847/1538-4357/ac7c0c

Using stellar population synthesis models to infer star formation histories (SFHs), we analyze photometry and spectroscopy of a large sample of quiescent galaxies that are members of Sunyaev–Zel'dovich (SZ)-selected galaxy clusters across a wide rang...

We investigate the strong-lensing cluster Abell 370 (A370) using a wide Integral Field Unit (IFU) spectroscopic mosaic from the Multi-Unit Spectroscopic Explorer (MUSE). IFU spectroscopy provides significant insight into the structure and mass conten... Read More about Pilot-WINGS: An extended MUSE view of the structure of Abell 370.
