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…
Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
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…
