A Deep Study of the Spiral Galaxy W2246f
Evelyn J. Johnston, Sorya Lambert, Aparna Nair +10
In this era of large surveys and statistical studies of galaxies, the beauty in the details of individual galaxies is often lost. We present a deep study of the spiral galaxy W2246…
Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1
Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7
Context. Giant Low Surface Brightness galaxies, such as Malin 1, host extended discs exceeding 100 kpc. Their formation and evolution remain debated, with interactions with satelli…
Unveiling large-scale rotational motions in the intragroup medium at z~1 through gravitational-arc tomography
Cédric Ledoux, Fernanda Muñoz-Olivares, L. Felipe Barrientos +8
We present the first spatially resolved characterisation of the cool intragroup medium (IGrM) in a spectroscopically confirmed galaxy group at z=1.167. Using 30 independent sightli…
A z1 galactic-scale outflow transversally mapped to 50 kpc through gravitational-arc tomography
J. A. Hernández-Guajardo, L. F. Barrientos, S. López +12
We report spatially resolved measurements of cool gas traced by Mg II and Fe II absorption in the circumgalactic medium (CGM) of a star-forming galaxy at (G1). The fortuit…
