Exploring the Thermal State of the Low-Density Intergalactic Medium at z=3 with an Ultra-High Signal-to-Noise QSO Spectrum
A. Rorai, G. D. Becker, M. G. Haehnelt +11
At low densities the standard ionisation history of the intergalactic medium (IGM) predicts a decreasing temperature of the IGM with decreasing density once hydrogen (and helium) r…
Triple-ionised carbon associated with the low-density neutral hydrogen gas at 1.7 < z < 3.3: the integrated N(HI)-N(CIV) relation
Tae-Sun Kim, R. F. Carswell, C. Mongardi +4
From the Voigt profile fitting analysis of 183 intervening CIV systems at 1.7 < z < 3.3 in 23 high-quality UVES/VLT and HIRES/Keck QSO spectra, we find that a majority of CIV syste…
Major Cluster Mergers and the Location of the Brightest Cluster Galaxy
Hugo Martel, Fidèle Robichaud, Paramita Barai
Using a large N-body cosmological simulation combined with a subgrid treatment of galaxy formation, we study the formation and evolution of the galaxy and cluster population in a c…
Simulated star formation rate functions at z~4-7, and the role of feedback in high-z galaxies
Edoardo Tescari, Antonios Katsianis, Stuart Wyithe +5
We study the role of feedback from supernovae and black holes in the evolution of the star formation rate function (SFRF) of z~4-7 galaxies. We use a new set of cosmological hydrod…
Kinetic or thermal AGN feedback in simulations of isolated and merging disk galaxies calibrated by the M-sigma relation
Paramita Barai, Matteo Viel, Giuseppe Murante +2
(Abridged) We investigate two modes of coupling the feedback energy from a central AGN to the neighboring gas in galaxy simulations: kinetic - velocity boost, and thermal - heating…
Galactic Winds in Cosmological Simulations of the Circumgalactic Medium
Paramita Barai, Matteo Viel, Stefano Borgani +7
(Abridged) We explore new observationally-constrained sub-resolution models of galactic outflows and investigate their impact on the circumgalactic medium (CGM) over redshifts z =…
