A Measurement of the Thermal and Ionization State of the IGM at
Teng Hu, Vikram Khaire, Joseph F. Hennawi +4
We apply a machine-learning-based inference method that exploits the joint Doppler parameter-column density (b-NHI) distribution from Lya forest decomposition to measure the therma…
Finding Halos in the Lyman- forest I. Introducing a hierarchical absorption framework
Duarte Muñoz Santos, Matthew M. Pieri, Dylan Nelson +3
It has been demonstrated that one can track down galaxies in absorption 'hidden' in the Lyman- forest through the use of 'strong, blended Lyman-' (or SBLA) absorption. Specif…
Searching for the Imprints of AGN Feedback on the Lyman Alpha Forest Around Luminous Red Galaxies
Vikram Khaire, Teng Hu, Joseph F. Hennawi +3
We explore the potential of using the low-redshift Lyman- (Ly) forest surrounding luminous red galaxies (LRGs) as a tool to constrain active galactic nuclei (AGN) feedback mo…
Measurements of the Thermal and Ionization State of the Intergalactic Medium during the Cosmic Afternoon
Teng Hu, Vikram Khaire, Joseph F. Hennawi +4
We perform the first measurement of the thermal and ionization state of the intergalactic medium (IGM) across 0.9 < z < 1.5 using 301 \lya absorption lines fitted from 12 HST STIS…
The Impact of the WHIM on the IGM Thermal State Determined from the Low- Lyman- Forest
Teng Hu, Vikram Khaire, Joseph F. Hennawi +4
At , shock heating caused by large-scale velocity flows and possibly violent feedback from galaxy formation, converts a significant fraction of the cool gas ($T\sim 1…
Can the Low Redshift Lyman Alpha Forest Constrain AGN Feedback Models?
Vikram Khaire, Teng Hu, Joseph F. Hennawi +2
We investigate the potential of low-redshift Lyman alpha (Ly) forest for constraining active galactic nuclei (AGN) feedback models by analyzing the Illustris and IllustrisTNG si…
Measuring the thermal and ionization state of the low- IGM using likelihood free inference
Teng Hu, Vikram Khaire, Joseph F. Hennawi +6
We present a new approach to measure the power-law temperature density relationship and the UV background photoionization rate of the IGM base…
