Turbulence in the multi-phase circumgalactic medium: bridging TNG50 and idealized kpc-scale simulations
Jonas Biba, Dylan Nelson
The circumgalactic medium (CGM) is the extended multi-phase gaseous halo surrounding a galaxy. To study how its dynamics are shaped by the interplay of radiative cooling and turbul…
Studying the absorption signatures of H I Lyman-α in the warm-hot circumgalactic medium with TNG50
P. Aparicio Marcos, P. Richter, M. Sparre +2
In this study, we investigate the spectral signatures of neutral hydrogen Lyman- absorption arising from the warm-hot gas component of the circumgalactic medium (CGM) around $z=…
Analysis of synthetic OVI absorption associated with galaxy groups in SIMBA and TNG50 simulations
Tanmay Singh, Sanchayeeta Borthakur, Dylan Nelson +2
We compare OVI absorption in synthetic spectra from galaxy groups in the SIMBA and TNG50 cosmological hydrodynamic simulations against those observed from the COS-IGrM survey. We s…
Two Channels of Metal-Rich Compact Stellar System Formation: Starbursts under High Ram Pressure versus Tidal Stripping
Yuan Bian, Min Du, Victor P. Debattista +9
Most galaxies follow well-defined scaling relations of metallicity and stellar mass; however, some outliers at the low mass end of the observed galaxy population exhibit unusually…
