MUSE Analysis of Gas around Galaxies (MAGG) -- VII. Emission line galaxies near strong blended Ly$\alpha$ absorption systems at $z\gtrsim3$

Davide Tornotti, Marta Galbiati, Matteo Fossati, Matthew Pieri, Michele Fumagalli

Strong blended Lyα absorption systems at z greater than 3 show a clear spatial and velocity correlation with nearby Lyα emitting galaxies.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find a strong correlation with LAEs within a projected distance of R≤300 kpc and line-of-sight velocity separation of |Δv|≤300 km s−1. The association rate increases significantly with decreasing flux, a trend that persists also at smaller separations (R<100 kpc).

C2weakest assumption

That the chosen flux thresholds and velocity windows isolate physically associated systems rather than projection effects or unrelated absorbers, with the correlation arising from genuine CGM connections.

C3one line summary

Strong blended Lyα absorbers cluster with Lyα emitting galaxies at z>3 within 300 kpc and 300 km/s, confirming they trace the circumgalactic medium interface.
