Lumina is a 500 cMpc radiation-hydrodynamic simulation predicting late, stellar-driven hydrogen reionization ending near z≈4.75 and AGN-driven helium reionization nearly complete by z=3.
Detection of helium lines in Balmer-dominated shocks of Type Ia SNRs reveals enhanced helium in some remnants and challenges shock models, enabling new constraints on progenitor environments.
Direct collapse black holes born at z=25.7 grow at half-Eddington rate to produce overmassive black hole galaxies at z~10 with M_BH/M_* ~0.01, matching JWST observations of GN-z11, UHZ1, and GHZ9 through initial star-formation suppression and later Pop III supernova metal blowout.
XRISM observations show the core of Abell 2199 is kinematically coherent with low turbulence, where turbulent heating may offset ~20% of radiative cooling losses.
Galaxies become less concentrated, more asymmetric and less clumpy toward lower stellar masses, with bar fraction declining to zero near 10^8 solar masses and CAS parameters losing separating power in the dwarf regime.
Machine learning on simulated images identifies that flux eruption events cause more diffuse, polarized, lower-flux millimeter emission with decreased Q-U loop rotation rate, achieving ~80% accuracy with random forests on summary statistics.
A homogenized ICL definition applied to Horizon-AGN, TNG100, Gizmo-Simba and Hydrangea yields consistent z=0 fractions of 0.1-0.2 with no significant redshift evolution and dominant contributions from satellites of 10^10.5-10^11.5 solar masses.
X-ray non-detection of little red dots requires both Compton-thick gas columns (~1e25 cm^-2) and intrinsically weak X-ray emission with bolometric correction k_bol,X ≳ 30.
A simulation study finds that a hot gas halo at galaxy total mass ~10^12.5 solar masses suppresses cool gas accretion, driving a redshift-independent turnover in the stellar-to-total mass ratio via reduced in-situ star formation efficiency.
New ALMA CO(1-0) data at 100-pc resolution reveal jet-induced molecular cloud disruption in NGC 1316, producing high extended gas fraction, broad lines, and elevated line ratios near the jet.
TNG50 simulation analysis finds early-forming halos show higher stellar mass, metallicity, lower CGM gas mass and sSFR at z=0, with mass-dependent CGM metallicity reversal and cold-gas kinematics differences.
The TNG SAM reproduces TNG hydro simulation gas and metal flows plus galaxy and halo properties within 30% accuracy out to z=6 via five targeted updates to the Santa Cruz SAM calibrated on stellar feedback-dominated galaxies.
Cooler CGM phases traced by Ca II and Mg II exhibit steeper radial equivalent width profiles than the warmer C IV phase, with host-type differences and stellar-mass dependence.
Halo-driven transient rapid growth followed by thermodynamic suppression explains over-massive black holes and Little Red Dots as precursors to standard SMBH-galaxy coevolution.
The paper identifies underproduction of oxygen in low-mass simulated dwarf galaxies as the likely cause of missing OVI in the CGM, based on comparisons across two simulation suites.
Horizon-AGN shows galaxy and black hole merger rates both rise with stellar mass and fall with redshift, peaking near z=2-3, establishing a direct evolutionary link from galaxy interactions to black hole coalescences.
Spectra of the western eROSITA bubbles reveal two uniform components at 0.60 keV and 0.21 keV with sub-solar abundances, plus a geometrical model constraining horizontal size to ~6 kpc but leaving vertical extent uncertain.
UV background suppresses NEI in galaxy haloes, restoring equilibrium shock thresholds and producing extended absorption columns for OVI, CIV, and HI beyond the virial radius.
A large collaboration compiles and compares merger rate predictions for massive black holes across multiple galaxy formation models to forecast LISA detections and quantify uncertainties.
XRISM data show a ~2 keV cooler gas phase with 300-400 km/s dispersion and bulk motion in the central Perseus cluster, distinct from the single-temperature gas beyond 60 kpc.
COLIBRE calibrates supernova and AGN feedback parameters in multi-phase ISM cosmological simulations using emulator-based fitting to reproduce the z=0 galaxy stellar mass function and size-stellar mass relation at three resolutions.
High-resolution simulations produce compact galaxies where gas inflows and dynamical processes accumulate enough mass in 10 Myr to form ~10^6 solar mass central black holes under 10% feedback efficiency.
GRRMHD simulations of CEM-adapted tori find thermal instability in 17-46 days with spin-dependent X-ray decline and soft excess matching AT2021ehb observations.
