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…
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…
A compact group lens modeled with GIGA-Lens: Enhanced inference for complex systems
F. Urcelay, E. Jullo, L. F. Barrientos +2
In the era of large-scale astronomical surveys, fast modeling of strong lens systems has become increasingly vital. While significant progress has been made for galaxy-scale lenses…
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…
