Probing the cosmic web with fast radio bursts: II. Scintillation
Sharon Lapiner, Nir Mandelker, Paz Beniamini +1
We consider the formation of multiphase gas in cosmic web objects (CWOs) through cooling and fragmentation within the shock-heated medium of cosmic sheets and filaments, and the ci…
Probing the Cosmic Web with Fast Radio Bursts. I. Scattering
Sharon Lapiner, Nir Mandelker, Paz Beniamini +1
We study the formation of multiphase gas in the post-accretion-shock regions of cosmic sheets, filaments, and the circumgalactic medium (CGM) of haloes, i.e., cosmic web objects (C…
The Structure and Dynamics of Massive High- Cosmic-Web Filaments: Three Radial Zones in Filament Cross-Sections
Yue Samuel Lu, Nir Mandelker, S. Peng Oh +5
We analyse the internal structure and dynamics of cosmic-web filaments that connect massive high- haloes. Our analysis is based on a high-resolution AREPO cosmological simulatio…
Thermal Instabilities and Shattering in the High-Redshift WHIM: Convergence Criteria and Implications for Low-Metallicity Strong HI Absorbers
Nir Mandelker, Frank C. van den Bosch, Volker Springel +5
Using a novel suite of cosmological simulations zooming in on a Mpc-scale intergalactic sheet or "pancake" at z~3-5, we conduct an in-depth study of the thermal properties and HI c…
Ly Blobs from Cold Streams Undergoing Kelvin-Helmholtz Instabilities
Nir Mandelker, Frank C. van den Bosch, Daisuke Nagai +3
We present an analytic toy model for the radiation produced by the interaction between the cold streams thought to feed massive halos at high redshift and their hot CGM. We begin b…
An analytic solution for the minimal bathtub toy model: challenges in the star-formation history of high-z galaxies
Avishai Dekel, Nir Mandelker
We study the minimal ``bathtub" toy model as an analytic tool for capturing key processes of galaxy evolution and identifying robust successes and challenges in reproducing observa…
