We use H I absorption along the lines-of-sight to the Q0107 quasar triplet in order to model potential disc and outflow structures in the circumgalactic medium of intervening galaxies at z ≲ 1, as well as the intergalactic medium on scales of up to a...

CUBES is a high efficiency spectrograph designed for a Cassegrain focus of the Very Large Telescope and is expected to be in operation in 2028. It is designed to observe point or compact sources in a spectral range from 300 to 405nm. CUBES will provi...

Probing the parameters of the intergalactic medium using quasars (2022)
Journal Article
Dalton, T., Morris, S. L., Fumagalli, M., & Gatuzz, E. (2022). Probing the parameters of the intergalactic medium using quasars. Monthly Notices of the Royal Astronomical Society, 513(1), 822-834. https://doi.org/10.1093/mnras/stac814

We continue our series of papers on intergalactic medium (IGM) tracers using quasi-stellar objects (QSOs), having examined gamma-ray bursts (GRBs) and blazars in earlier studies. We have estimated the IGM properties of hydrogen column density (⁠NHXIG... Read More about Probing the parameters of the intergalactic medium using quasars.
