A consistent and robust measurement of the thermal state of the IGM at 2 ≤ z ≤ 4 from a large sample of Ly α forest spectra
We characterise the thermal state of the intergalactic medium (IGM) in ten
redshift bins in the redshift range $2 \leq z \leq 4$ with a sample of 103 high
resolution, high S/N Ly$\alpha$ forest spectra using four different...
The host galaxies of FeLoBAL quasars at z ∼ 0.9 are not dominated by recent major mergers

Theoretical models have suggested an evolutionary model for quasars, in which most of luminous quasars are triggered by major mergers. It is also postulated that reddening as well as powerful outflows indicate an early phase...
Gas around galaxy haloes - III
Modern theories of galaxy formation predict that galaxies impact on their gaseous surroundings, playing the fundamental role of regulating the amount of gas converted into stars. While star-forming galaxies are believed to...
