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…
A Magnetized Black Hole Envelope Model for Little Red Dots
Shinsuke Takasao, Kohei Inayoshi
Recent observations have revealed a unique class of active galactic nuclei (AGNs), termed little red dots (LRDs). These objects are hypothesized to be powered by massive black hole…
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…
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…
Spontaneous Formation of Outflows Powered by Rotating Magnetized Accretion Flows in a Galactic Center
Shinsuke Takasao, Yuri Shuto, Keiichi Wada
We investigate how magnetically driven outflows are powered by a rotating, weakly magnetized accretion flow onto a supermassive black hole using axisymmetric magnetohydrodynamic si…
