ALMA visits the QSO MUSEUM: Connecting molecular gas and the cool circumgalactic medium around 37 z~3 quasars
Jelena Ritter, Fabrizio Arrigoni Battaia, Bo Peng +7
Extended Ly emission is ubiquitous around quasars and traces the cool circumgalactic medium, providing insights into halo gas dynamics and active galactic nucleus feedback. Howe…
Constraining the nature of active galactic nuclei through circumgalactic Lya emission at z=2-3
Shiwu Zhang, Zheng Cai, Fabrizio Arrigoni Battaia +8
We present a comprehensive analysis of circumgalactic Lya nebulae around 59 unobscured and 26 obscured quasars at z=2-3, observed with the Keck Cosmic Web Imager (KCWI), to constra…
RUBIX: Differentiable forward modelling of galaxy spectral data cubes for gradient-based parameter estimation
Anna Lena Schaible, Ufuk Ãakır, Tobias Buck +5
Although integral-field spectroscopy enables spatially resolved spectral studies of galaxies, bridging particle-based simulations to observations remains slow and non-differentiabl…
Testing the AGN unified model with simulated emission lines from the circumgalactic medium (CGM)
Shiwu Zhang, Zheng Cai, Aura Obreja +5
The CGM around unobscured AGN has received much attention in recent years. Comparatively, nebulae associated with obscured AGN are less studied. Here, we simulate the Ly, H…
QSO MUSEUM III: the circumgalactic medium in Ly emission around 120 quasars covering the SDSS parameter space. Witnessing the instantaneous AGN feedback on halo scales
Jay González Lobos, Fabrizio Arrigoni Battaia, Aura Obreja +3
Recent surveys show that quasars are surrounded by Hydrogen Lyman- (Ly) glows with diverse emission levels and extents. These seem to depend on the activity of embedd…
Bridging Simulations and Observations: New Insights into Galaxy Formation Simulations via Out-of-Distribution Detection and Bayesian Model Comparison
Lingyi Zhou, Stefan T. Radev, William H. Oliver +3
Cosmological simulations are a powerful tool to advance our understanding of galaxy formation and many simulations model key properties of real galaxies. A question that naturally…
