MUSEQuBES: Calibrating the redshifts of Ly α emitters using stacked circumgalactic medium absorption profiles

Sowgat Muzahid, Joop Schaye, Raffaella Anna Marino +17

Lyman (Ly) emission lines are typically found to be redshifted with respect to the systemic redshifts of galaxies, likely due to resonant scattering of Ly photons. Here w…

The resolved size and structure of hot dust in the immediate vicinity of AGN

GRAVITY Collaboration, J. Dexter, J. Shangguan +42

We use VLTI/GRAVITY near-infrared interferometry measurements of 8 bright, Type 1 AGN to study the size and structure of hot dust heated by the central engine. We partially resolve…

New criteria for the selection of galaxy close pairs from cosmological simulations: evolution of the major and minor merger fraction in MUSE deep fields

E. Ventou, T. Contini, N. Bouché +8

It is still a challenge to assess the merger fraction of galaxies at different cosmic epochs in order to probe the evolution of their mass assembly. Using the Illustris cosmologica…
