Journal Article
Conroy, C., Johnson, B. D., van Dokkum, P., Deason, A., Tacchella, S., Belli, S., …Emami, R. (2024). Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST. The Astrophysical Journal, 968(2), Article 129. https://doi.org/10.3847/1538-4357/ad414a

We report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 (M * = 5 × 109 M ⊙; d = 35 Mpc) in deep JWST NIRCam imaging from the Blue Jay Survey. The F200W–F444W color provides robust star–galaxy separati... Read More about Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST.

Impacts of Bar-driven Shear and Shocks on Star Formation (2024)
Journal Article
Kim, T., Gadotti, D. A., Querejeta, M., Pérez, I., Zurita, A., Neumann, J., van de Ven, G., Méndez-Abreu, J., de Lorenzo-Cáceres, A., Sánchez-Blázquez, P., Fragkoudi, F., Martins, L. P., Silva-Lima, L. A., Kim, W.-T., & Park, M.-G. (2024). Impacts of Bar-driven Shear and Shocks on Star Formation. The Astrophysical Journal, 968(2), Article 87. https://doi.org/10.3847/1538-4357/ad410e

Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and change the gas properties. For four barred galaxies, we present Hα velocity gradient maps th... Read More about Impacts of Bar-driven Shear and Shocks on Star Formation.

ARTEMIS emulator: exploring the effect of cosmology and galaxy formation physics on Milky Way-mass haloes and their satellites (2024)
Journal Article

Monthly Notices of the Royal Astronomical Society, 532(2), 1223-1240. https://doi.org/10.1093/mnras/stae1378

We present the new ARTEMIS emulator suite of high-resolution (baryon mass of 2.23 × 104h−1 M⊙) zoom-in simulations of Milky Way-mass systems. Here, three haloes from the original ARTEMIS sample have been rerun multiple times, systematically varying p...

First evidence of a connection between cluster-scale diffuse radio emission in cool-core galaxy clusters and sloshing features (2024)
Journal Article
Biava, N., Bonafede, A., Gastaldello, F., Botteon, A., Brienza, M., Shimwell, T. W., …Tasse, C. (2024). First evidence of a connection between cluster-scale diffuse radio emission in cool-core galaxy clusters and sloshing features. Astronomy & Astrophysics, 686, Article A82. https://doi.org/10.1051/0004-6361/202348045

Context. Radio observations of a few cool-core galaxy clusters have revealed the presence of diffuse emission on cluster scales, similar to what was found in merging clusters in the form of radio halos. These sources might suggest that a minor merger... Read More about First evidence of a connection between cluster-scale diffuse radio emission in cool-core galaxy clusters and sloshing features.
