A young star-forming galaxy at z = 3.5 with an extended Ly\, halo seen with MUSE
Vera Patrício, Johan Richard, Anne Verhamme +12
Spatially resolved studies of high redshift galaxies, an essential insight into galaxy formation processes, have been mostly limited to stacking or unusually bright objects. We pre…
Constraining the lifetime and opening angle of quasars using fluorescent Lyman emission: the case of Q0420-388
Elena Borisova, Simon J. Lilly, Sebastiano Cantalupo +3
A toy model is developed to understand how the spatial distribution of fluorescent emitters in the vicinity of bright quasars could be affected by the geometry of the quasar bi-con…
Extended Lyman alpha haloes around individual high-redshift galaxies revealed by MUSE
L. Wisotzki, R. Bacon, J. Blaizot +22
We report the detection of extended Ly alpha emission around individual star-forming galaxies at redshifts z = 3-6 in an ultradeep exposure of the Hubble Deep Field South obtained…
Probing the end of reionization with the near-zones of z > 6 QSOs
Laura C. Keating, Martin G. Haehnelt, Sebastiano Cantalupo +1
QSO near-zones are an important probe of the the ionization state of the IGM at z ~ 6-7, at the end of reionization. We present here high-resolution cosmological 3D radiative trans…
Quasar Quartet Embedded in Giant Nebula Reveals Rare Massive Structure in Distant Universe
Joseph F. Hennawi, J. Xavier Prochaska, Sebastiano Cantalupo +1
All galaxies once passed through a hyperluminous quasar phase powered by accretion onto a supermassive black hole. But because these episodes are brief, quasars are rare objects ty…
Deep HeII and CIV Spectroscopy of a Giant Lyman alpha Nebula: Dense Compact Gas Clumps in the Circumgalactic Medium of a z~2 Quasar
Fabrizio Arrigoni Battaia, Joseph F. Hennawi, J. Xavier Prochaska +1
The recent discovery by Cantalupo et al. (2014) of the largest (~500 kpc) and luminous Ly-alpha nebula associated with the quasar UM287 (z=2.279) poses a great challenge to our cur…
