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.…
Uncertainty-Aware Deep Learning for the Ly Forest: CNN-Based Absorber Detection and Characterization
Paryag Sharma, Vikram Khaire, Ting-Yun Cheng +2
The Ly forest is a powerful probe of the intergalactic medium and small-scale matter distribution, but deriving absorber properties traditionally requires computationally expen…
NISER-IUCAA New Simulations of JWST GAlaxies and Quasars(NINJA): Properties of galaxies at
Ranit Behera, Raghunathan Srianand, Nishikanta Khandai +1
We present the NINJA suite of cosmological hydrodynamical simulations developed to investigate galaxy formation and evolution at in the era of JWST. Using our fiducia…
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…
E-XQR-30: Evidence for an Increase in the Ionization State of Metal Absorbers from z~6 to z~2
Stephanie Rowlands, R. L. Davies, E. Ryan-Weber +15
We investigate the evolution of the ionization state of metal-enriched gas in and around galaxies near the epoch of reionization using a sample of 488 metal absorption systems at 4…
Efficient Modelling of Lyman-α opacity fluctuations during late reionization epoch
Barun Maity, Frederick Davies, Prakash Gaikwad
The Lyman- forest opacity fluctuations observed from high-redshift quasar spectra have been proven to be extremely successful in order to probe the late phase of the reionizati…
