Revealing the Impact of Quasar Luminosity on Giant Ly Nebulae
Ruari Mackenzie, Gabriele Pezzulli, Sebastiano Cantalupo +6
We present the results from a MUSE survey of twelve quasars, which were selected to be much fainter (20<i<23) than in previous studies of Giant Ly Nebulae around t…
The nature of CR7 revealed with MUSE: a young starburst powering extended Lyman- emission at z=6.6
Jorryt Matthee, Gabriele Pezzulli, Ruari Mackenzie +11
CR7 is among the most luminous Lyman- emitters (LAEs) known at and consists of at least three UV components that are surrounded by Lyman- (Ly) emission. Previous…
Probing the AGN Unification Model at redshift z 3 with MUSE observations of giant Ly nebulae
J. S. den Brok, S. Cantalupo, R. Mackenzie +7
A prediction of the classic active galactic nuclei (AGN) unification model is the presence of ionisation cones with different orientations depending on the AGN type. Confirmations…
Lyman-alpha transmission properties of the intergalactic medium in the CoDaII simulation
Max Gronke, Pierre Ocvirk, Charlotte Mason +10
The decline in abundance of Lyman- (Ly) emitting galaxies at is a powerful and commonly used probe to constrain the progress of cosmic reionization. We use the…
The MUSE Hubble Ultra Deep Field Survey XIV. The evolution of the Lya emitter fraction from z=3 to z=6
Haruka Kusakabe, Jeremy Blaizot, Thibault Garel +19
The Lya emitter (LAE) fraction, X_LAE, is a potentially powerful probe of the evolution of the intergalactic neutral hydrogen gas fraction. However, uncertainties in the measuremen…
Elevated ionizing photon production efficiency in faint high-equivalent-width Lyman-alpha emitters
Michael V. Maseda, Roland Bacon, Daniel Lam +16
While low-luminosity galaxies dominate number counts at all redshifts, their contribution to cosmic Reionization is poorly understood due to a lack of knowledge of their physical p…
