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.

The ram pressure stripped radio tails of galaxies in the Coma cluster (2020)
Journal Article

Previous studies have revealed a population of galaxies in galaxy clusters with ram pressure stripped (RPS) tails of gas and embedded young stars. We observed 1.4 GHz continuum and H I emission with the Very Large Array in its B-configuration in two... Read More about The ram pressure stripped radio tails of galaxies in the Coma cluster.

The Regulation of Galaxy Growth along the Size–Mass Relation by Star Formation, as Traced by Hα in KMOS3D Galaxies at 0.7 ≲ z ≲ 2.7. Astrophysical Journal, 892(1), Article 1. https://doi.org/10.3847/1538-4357/ab7914

We present half-light sizes measured from $\,{\rm{H}}\alpha $ emission tracing star formation in 281 star-forming galaxies from the $\,{\mathrm{KMOS}}^{3{\rm{D}}}$ survey at $\,0.7\lesssim z\lesssim 2.7$. Sizes are derived by fitting 2D exponential d... Read More about The Regulation of Galaxy Growth along the Size–Mass Relation by Star Formation, as Traced by Hα in KMOS3D Galaxies at 0.7 ≲ z ≲ 2.7.

The Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) is a blind narrow-band Hα + [NII] imaging survey of the Virgo cluster carried out with MegaCam at the Canada-French-Hawaii telescope. We use a new set of data extracted from VESTIG... Read More about A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE): VI. Environmental quenching on HII-region scales.

Direct Detection of Black Hole-driven Turbulence in the Centers of Galaxy Clusters (2020)

Supermassive black holes (SMBHs) are thought to provide energy that prevents catastrophic cooling in the centers of massive galaxies and galaxy clusters. However, it remains unclear how this "feedback" process operates. We use high-resolution optical... Read More about Direct Detection of Black Hole-driven Turbulence in the Centers of Galaxy Clusters.
