Mapping the spatial extent of HI-rich absorbers using MgII absorption along gravitational arcs
Trystyn A. M. Berg, Andrea Afruni, Cédric Ledoux +6
HI-rich absorbers seen within quasar spectra contain the bulk of neutral gas in the Universe. However, the spatial extent of these reservoirs are not extensively studied due to the…
A lack of LAEs within 5Mpc of a luminous quasar in an overdensity at z=6.9: potential evidence of quasar negative feedback at protocluster scales
Trystan S. Lambert, R. J. Assef, C. Mazzucchelli +13
High-redshift quasars are thought to live in the densest regions of space which should be made evident by an overdensity of galaxies around them. However, campaigns to identify the…
Directly constraining the spatial coherence of the circumgalactic medium
A. Afruni, S. Lopez, P. Anshul +9
One of the biggest puzzles regarding the circumgalactic medium (CGM) is the structure of its cool ( K) gas phase. While the kinematics of quasar absorption systems sugge…
A Lyman-α protocluster at redshift 6.9
Weida Hu, Junxian Wang, Leopoldo Infante +21
Protoclusters, the progenitors of the most massive structures in the Universe, have been identified at redshifts of up to 6.6. Besides exploring early structure formation, searchin…
