Bayesian luminosity function estimation in multi-depth datasets with selection effects: A case study for Lyman emitters
Davide Tornotti, Matteo Fossati, Michele Fumagalli +3
We present a hierarchical Bayesian framework designed to infer the luminosity function of any class of object by jointly modelling data from multiple surveys with varying depth, co…

The MUSE Ultra Deep Field: A 5 Mpc stretch of the z 4 cosmic web revealed in emission
Davide Tornotti, Michele Fumagalli, Matteo Fossati +7
We detect Ly emission from a ~5 Mpc-long (comoving) portion of the cosmic web hosting an overdensity () of 19 Ly emitters (LAEs) at within the MU…

High-definition imaging of a filamentary connection between a close quasar pair at z=3
Davide Tornotti, Michele Fumagalli, Matteo Fossati +16
Filaments connecting halos are a long-standing prediction of cold dark matter theories. We present a detection of the cosmic web emission connecting two quasar-host galaxies at red…
