BLUEPRINT: Blue-dominant Lyman- emission as evidence of gas inflow in ultra-low-mass galaxies at z = 3

Tamal Mukherjee, Zhihui Li, Tayyaba Zafar +4

We report the detection of a clumpy, blue-dominated Ly emission at z = 3.066 located in the heart of a cosmic web filament in the MUSE eXtremely Deep Field (MXDF), spatially as…

HST's Deep Blue: extremely deep UV imaging to reveal the contributors to reionization

Ilias Goovaerts, Alexander Beckett, Matthew Hayes +12

Understanding galaxy evolution in the epoch of reionization and the effect these galaxies had on the transformation of the intergalactic medium from neutral to ionized, is a key go…

MUSE Analysis of Gas around Galaxies (MAGG) -- VII. Emission line galaxies near strong blended Ly absorption systems at

Marta Galbiati, Davide Tornotti, Michele Fumagalli +2

We investigate the connection between strong, blended Ly absorption systems (SBLAs) and Ly emitting galaxies (LAEs) at in 28 quasar fields from th…

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…
