Estimation of distribution functions, their jumps and interval probabilities under measurement error
Kairat Mynbaev, Carlos Martins-Filho, Chad Brown
We consider the classical additive measurement-error model , where the latent random variable has unknown distribution and the error has a known distribution.…
Ringing of the Reionization: A first direct measurement of the intergalactic pressure smoothing scale at redshift z>4.2 as imprinted onto small-scale peculiar velocities in the Lyman-alpha forest
Vid IrÅ¡iÄ, Matteo Viel, Martin G. Haehnelt +3
The epoch of reionization leaves detectable imprints in the thermal history of the Universe. In particular, the fast ionization fronts passing over cold gas in the cosmic web overp…
Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at with the 21-cm forest power spectrum
Tomáš Šoltinský, Arnab Chakraborty, Girish Kulkarni +10
Neutral regions of the intergalactic medium (IGM) during the Epoch of Reionization (EoR) remain largely unexplored due to the limitations of existing probes. Owing to discoveries o…
The impact of source and survey modelling on the connection between [O III] emitters and Ly forest transmission at z ~ 6
Luke Conaboy, James S. Bolton, Laura C. Keating +3
James Webb Space Telescope (JWST) surveys of [O III]-emitting galaxies are offering fresh insight into the connection between galaxies and the intergalactic medium at redshift z ~…
Post-inflationary axion constraints from the Lyman- forest
Olga Garcia-Gallego, Vid IrÅ¡iÄ, Matteo Viel +2
Among the most compelling cold dark matter candidates, the axion has recently been subject to a wide range of astrophysical studies aiming to constraints its properties. We present…
An improved model for the effect of correlated Si-III absorption on the one-dimensional Lyman- forest power spectrum
Ke Ma, James S. Bolton, Vid Irsic +2
We present an analysis of Si III absorption and its effect on the 1D Ly forest power spectrum using the Sherwood-Relics hydrodynamical simulation suite. In addition to oscillat…
