The Lyman- forest as a diagnostic of the nature of the dark matter
Antonella Garzilli, Andrii Magalich, Tom Theuns +4
The observed Lyman- flux power spectrum (FPS) is suppressed on scales below . This cutoff could be due to the high temperature, , and pressure, $p…
The broadening of Lyman-alpha forest absorption lines
Antonella Garzilli, Tom Theuns, Joop Schaye
We provide an analytical description of the line broadening of HI absorbers in the Lyman-alpha forest resulting from Doppler broadening and Jeans smoothing. We demonstrate that our…
The high-redshift (z>3) AGN population in the 4 Ms Chandra Deep Field South
F. Vito, C. Vignali, R. Gilli +10
We present results from a spectral analysis of a sample of high-redshift (z>3) X-ray selected AGN in the 4 Ms Chandra Deep Field South (CDF-S), the deepest X-ray survey to date. Th…
Constraining Star Formation and AGN in z~2 Massive Galaxies using High Resolution MERLIN Radio Observations
Caitlin M. Casey, Scott C. Chapman, Tom W. B. Muxlow +3
We present high spatial resolution MERLIN 1.4GHz radio observations of two high redshift (z~2) sources, RGJ123623 (HDF147) and RGJ123617 (HDF130), selected as the brightest radio s…
