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…

Cold Stream Penetration of Virial Shocks: Fragmentation, Coagulation, and Disruption in the Hot Circumgalactic Medium

Zhiyuan Yao, Nir Mandelker, S. Peng Oh

Cold streams penetrating virial shocks of massive halos along cosmic web filaments are expected to fuel galaxy growth at high redshift, yet the physical processes governing their p…

Feedback-Free Star Formation in Clusters within a Galaxy Simulated at High Resolution in Cosmic Dawn

Hou-Zun Chen, Zhaozhou Li, Avishai Dekel +3

We perform a cosmological zoom-in simulation of a massive galaxy ( at ) using the GIZMO code. By employing resolution and a $3.4\…

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…

Statistical Properties of Cold Streams In Massive Star-Forming Halos in TNG50

Isabel Medlock, Daisuke Nagai, Nir Mandelker +4

Cold, dense streams of gas are predicted to penetrate deeply into massive halos (> 10^12 Msun) at cosmic noon (z=4-2), fueling galaxies to sustain high star formation rates. We inv…

Impact of Cosmic Filaments on Galaxy Morphological Evolution and Predictions of Early Cosmic Web Structure for Roman

Farhanul Hasan, Haowen Zhang, Viraj Pandya +10

We leverage the IllustrisTNG cosmological simulations to test how the large-scale cosmic web shapes galaxy morphology and to forecast the early cosmic web structure that the Nancy…
