Magnetising galaxies with cold inflows
Nicolas Ledos, Evangelia Ntormousi, Shinsuke Takasao +1
High-redshift () galaxies accrete circumgalactic gas through cold streams. Recent high-resolution MHD simulations of these streams showed a significant amplification of t…
Stability and Ly emission of Cold Stream in the Circumgalactic Medium: impact of magnetic fields and thermal conduction
Nicolas Ledos, Shinsuke Takasao, Kentaro Nagamine
Cold streams of gas with temperatures around play a crucial role in the gas accretion on to high-redshift galaxies. The current resolution of cosmological simulatio…
Cosmic ray heating of cold streams: Implications for the gas supply and growth of massive galaxies
Ellis R. Owen, Nicolas Ledos, Evangelia Ntormousi +3
Recent observations have demonstrated the presence of cosmic rays (CRs) in cosmic-web filaments. Cold streams supply gas inflows from these filaments into massive galaxies during t…
The hydrodynamical response of cold circumgalactic clouds to quasar radiation
Nicolas Ledos, Sebastiano Cantalupo, Titouan Lazeyras +8
Recent simulations increasingly resolve the small-scale structure of the circumgalactic medium (CGM), but the dynamical impact of ionising radiation on its cold K component…
A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
Infrared Imaging using thermally stable HgTe/CdS nanocrystals
Huichen Zhang, Yoann Prado, Rodolphe Alchaar +20
Transferring the nanocrystals (NCs) from the laboratory environment toward practical applications has raised new challenges. In the case of NCs for display and lightning, the focus…
