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…

Gaseous Dynamical Friction: a Numerical Study of Extended Perturbers
Ben Morton, Sadegh Khochfar, Jose Oñorbe
The process of momentum and energy transfer between a massive body and a background medium it is moving through is known as dynamical friction (DF). It is key to our understanding…

Hidden Figures in the Sky: Evolution of low-surface brightness galaxies from a hydro-dynamical perspective
D. Stoppacher, P. Tissera, Y. Rosas-Guevara +2
Low-surface brightness galaxies (LSBGs) are defined as galaxies with central surface brightness levels fainter than the night sky, making them challenging to observe. A key open qu…
