Spitzer-selected z > 1.3 protocluster candidates in the LSST deep-drilling fields (2023)
Journal Article
Gully, H., Hatch, N., Bahé, Y., Balogh, M., Bolzonella, M., Cooper, M. C., …Wilson, G. (2024). Spitzer-selected z > 1.3 protocluster candidates in the LSST deep-drilling fields. Monthly Notices of the Royal Astronomical Society, 527(4), 10680-10696. https://doi.org/10.1093/mnras/stad3885

We have identified 189 candidate z > 1.3 protoclusters and clusters in the LSST Deep Drilling Fields. This sample will enable the measurement of the metal enrichment and star formation history of clusters during their early assembly period through th...

The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters (2023)
Journal Article
Edward, A. H., Balogh, M. L., Bahé, Y. M., Cooper, M. C., Hatch, N. A., Marchioni, J., …Xie, L. (2024). The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters. Monthly Notices of the Royal Astronomical Society, 527(3), 8598–8617. https://doi.org/10.1093/mnras/stad3751

We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between 2.0 < z < 2.5 in the COSMOS field, down to a mass limit of 10 9.5 M⊙. We use existing photometric redshifts with a statistical background subtraction,... Read More about The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters.

COALAS II. Extended molecular gas reservoirs are common in a distant, forming galaxy cluster (2023)
Journal Article
Chen, Z., Dannerbauer, H., Lehnert, M., Emonts, B. H. C., Gu, Q., Allison, J. R., …Ziegler, B. (2024). COALAS II. Extended molecular gas reservoirs are common in a distant, forming galaxy cluster. Monthly Notices of the Royal Astronomical Society, 527(3), 8950–8972. https://doi.org/10.1093/mnras/stad3128

This paper presents the results of 475 hours of interferometric observations with the Australia Telescope Compact Array towards the Spiderweb protocluster at (z=2.16). We search for large, extended molecular gas reservoirs among 46 previously detecte... Read More about COALAS II. Extended molecular gas reservoirs are common in a distant, forming galaxy cluster.

Intracluster light in the core of z ∼ 2 galaxy proto-clusters (2023)
Journal Article
Werner, S. V., Hatch, N. A., Matharu, J., Gonzalez, A. H., Bahé, Y. M., Mei, S., …Wylezalek, D. (2023). Intracluster light in the core of z ∼ 2 galaxy proto-clusters. Monthly Notices of the Royal Astronomical Society, 523(1), 91-104. https://doi.org/10.1093/mnras/stad1410

Intracluster light is thought to originate from stars that were ripped away from their parent galaxies by gravitational tides and galaxy interactions during the build up of the cluster. The stars from such interactions will accumulate over time, so s... Read More about Intracluster light in the core of z ∼ 2 galaxy proto-clusters.

A cosmic stream of atomic carbon gas connected to a massive radio galaxy at redshift 3.8 (2023)
Journal Article
Emonts, B. H., Lehnert, M. D., Yoon, I., Mandelker, N., Villar-Martín, M., Miley, G. K., …Guillard, P. (2023). A cosmic stream of atomic carbon gas connected to a massive radio galaxy at redshift 3.8. Science, 379(6639), 1323-1326. https://doi.org/10.1126/science.abh2150

The growth of galaxies in the early Universe is driven by accretion of circum- and intergalactic gas. Simulations have predicted that steady streams of cold gas penetrate the dark matter halos of galaxies and provide the raw material necessary to sus...
