Recovering the effective impact parameters in integral-field absorption-line tomography
J. A. Hernández-Guajardo, L. F. Barrientos, C. Ledoux +3
Integral-field-unit (IFU) spectroscopy of extended background sources, such as gravitational arcs, delivers many closely spaced absorption sightlines through the circumgalactic med…
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…
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
Giant Low Surface Brightness galaxies (gLSBGs), such as Malin 1, host extended stellar and gaseous discs exceeding in radius. Their formation and evolution remai…
Mapping the spatial extent of HI-rich absorbers using MgII absorption along gravitational arcs
Trystyn A. M. Berg, Andrea Afruni, Cédric Ledoux +6
HI-rich absorbers seen within quasar spectra contain the bulk of neutral gas in the Universe. However, the spatial extent of these reservoirs are not extensively studied due to the…
First Detection of Molecular Gas in the Giant Low Surface Brightness Galaxy Malin 1
Gaspar Galaz, Jorge González-López, Viviana Guzmán +17
After over three decades of unsuccessful attempts, we report the first detection of molecular gas emission in Malin 1, the largest spiral galaxy observed to date, and one of the mo…
Transverse clues on the kpc-scale structure of the circumgalactic medium as traced by C IV absorption
S. Lopez, A. Afruni, D. Zamora +13
We present VLT/MUSE integral-field spectroscopy () of four giant gravitational arcs exhibiting strong C IV absorption at 8 intervening redshifts, $z_{abs}\approx 2…
A MUSE View of the Core of the Giant Low Surface Brightness Galaxy Malin 1
Evelyn J. Johnston, Gaspar Galaz, Matias Blaña +8
Aims. The central region of the Giant Low Surface Brightness galaxy Malin 1 has long been known to have a complex morphology with evidence of a bulge, disc, and potentially a bar h…
The ALMA-CRISTAL survey. Discovery of a 15 kpc-long gas plume in a Lyman- blob
M. Solimano, J. González-López, M. Aravena +24
Massive star-forming galaxies in the high-redshift universe host large reservoirs of cold gas in their circumgalactic medium (CGM). Traditionally, these reservoirs have been linked…
Directly constraining the spatial coherence of the circumgalactic medium
A. Afruni, S. Lopez, P. Anshul +9
One of the biggest puzzles regarding the circumgalactic medium (CGM) is the structure of its cool ( K) gas phase. While the kinematics of quasar absorption systems sugge…
MUSE observations of the giant low surface brightness galaxy Malin 1: Numerous HII regions, star formation rate, metallicity, and dust attenuation
Junais, P. M. Weilbacher, B. Epinat +6
Giant low-surface brightness (GLSB) galaxies are an extreme class of objects with very faint and extended gas-rich disks. Malin 1 is the largest GLSB galaxy known to date, but its…
