Filaments connecting haloes are a long-standing prediction of cold-dark-matter theories. Here we present a detection of the cosmic web emission connecting two quasar-host galaxies at redshift z ≈ 3.22 in the MUSE Ultra Deep Field (MUDF), observed wit...

The Large Survey Project (LSP) “MeerKAT Absorption Line Survey” (MALS) is a blind H I 21 cm and OH 18 cm absorption line survey in the L- and UHF-bands, primarily designed to better determine the occurrence of atomic and molecular gas in the circumga...

We present a study of the environment of 27 z = 3–4.5 bright quasars from the MUSE Analysis of Gas around Galaxies (MAGG) survey. With medium-depth Multi Unit Spectroscopic Explorer (MUSE) observations (4 h on target per field), we characterize the e... Read More about MUSE analysis of gas around galaxies (MAGG) – III.

Monthly Notices of the Royal Astronomical Society, 499(4), 5022-5046. https://doi.org/10.1093/mnras/staa3147

We present a study of the metal-enriched cool halo gas traced by Mg II absorption around 228 galaxies at z ∼ 0.8–1.5 within 28 quasar fields from the MUSE Analysis of Gas around Galaxies survey. We observe no significant evolution in the Mg II equiva... Read More about MUSE Analysis of Gas around Galaxies (MAGG) - II: Metal-enriched halo gas around z ∼ 1 galaxies.

Journal Article
Klitsch, A., Zwaan, M., Smail, I., Péroux, C., Biggs, A., Chen, C.-C., Ivison, R., Popping, G., Lagos, C., Béthermin, M., Swinbank, A., Hamanowicz, A., & Dutta, R. (2020).

Measurements of the cosmic far-infrared background (CIB) indicate that emission from many extragalactic phenomena, including star formation and black hole accretion, in the Universe can be obscured by dust. Resolving the CIB to study the population o... Read More about ALMACAL VII: First Interferometric Number Counts at 650 μm.
