We present the full public release of all data from the TNG50, TNG100 and TNG300 simulations of the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gravo-magnetohydrodynamical simulations run with the moving-mesh code Arepo. TNG includes a comprehensive model for galaxy formation physics, and each TNG simulation self-consistently solves for the coupled evolution of dark matter, cosmic gas, luminous stars, and supermassive blackholes from early time to the present day, z=0. Each of the flagship runs -- TNG50, TNG100, and TNG300 -- are accompanied by lower-resolution and dark-matter only counterparts, and we discuss scientific and numerical cautions and caveats relevant when using TNG. Full volume snapshots are available at 100 redshifts; halo and subhalo catalogs at each snapshot and merger trees are also released. The data volume now directly accessible online is ~1.1 PB, including 2,000 full volume snapshots and ~110,000 high time-resolution subbox snapshots. Data access and analysis examples are available in IDL, Python, and Matlab. We describe improvements and new functionality in the web-based API, including on-demand visualization and analysis of galaxies and halos, exploratory plotting of scaling relations and other relationships between galactic and halo properties, and a new JupyterLab interface. This provides an online, browser-based, near-native data analysis platform which supports user computation with fully local access to TNG data, alleviating the need to download large simulated datasets.

The mass-dependent interplay of active galacitc nuclei and supernova feedback in shaping the $L_{\rm X}$--$T$ relation of early-type galaxies
Mass-dependent coupling of AGN winds and supernovae, including a metal-lifting fountain in dwarfs, explains the steep L_X-T relation of early-type galaxies.

The COLIBRE-SKIRT pipeline: Calibration-free dust radiative transfer postprocessing for cosmological simulations
The COLIBRE-SKIRT pipeline reproduces the observed low-redshift cosmic SED without calibrating the post-processing, using live dust from the simulation and a new 'split & scale' grain-size mapping.

Ubiquitous Corotation of Dark Matter Halos: Implications for Direct Detection
Dark matter in simulated Milky Way analogues preferentially corotates with the baryonic disk, suppressing predicted direct-detection rates for light WIMPs, reducing directional modulation, and producing a 21% astrophy...

A study of the large-scale formation in the environment of A3266: Infalling groups, filaments, and a premerger cold front
A 3.6σ X-ray filament of length ~1.1 Mpc connects A3266 to a cool-core NW group that hosts a premerger cold front, with filament gas hotter and denser than pristine WHIM.

Identifying backsplash galaxies using machine learning
Machine learning trained on The Three Hundred simulations identifies backsplash galaxies in cluster outskirts with ~75% purity/completeness, and has been applied to HI-tail galaxies in Virgo.

Too many quiescent late-type galaxies or a matter of misclassification?
Quiescent late-type galaxies in SDSS morphological catalogues are overestimated by a factor of ~2 due to misclassified edge-on S0 galaxies.

The role of filaments in the large-scale conformity signal
Filamentary regions of the cosmic web are the primary contributors to the residual large-scale conformity signal of low-mass central galaxies in both SAG and TNG300.

AGN Feedback Models and AGN Demographics II: Comparing Predictions of Radiative and Total Feedback to Observations
EAGLE, SIMBA, and TNG100 all fail to reproduce observed trends in which galaxies host radiatively efficient AGN, and EAGLE matches only after a factor-of-ten normalization adjustment.

Fuelling the central region of galaxies with misaligned gas accretion
Kinematically misaligned gas accretion sustains main-sequence-level star formation only below ~1e10 Msun; above that, central gas is present but dilution by pre-existing mass keeps specific star formation low.

Probabilistic redshift estimation of unresolved galaxies from multi-band background light maps
Conditional normalising flows trained on mock multi-band images recover the redshift distribution of unresolved galaxies with sub-percent accuracy in mean and width, under idealized simulation-matched conditions.

Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years
Combining FAST and DESI data for 2.5 million galaxies shows cosmic atomic hydrogen density declined by only a factor of 1.35 over 4.5 Gyr, far less than the 2.46-fold decline in star formation.

Intrinsic alignment of disks and ellipticals across hydrodynamical simulations
With consistent shape and morphology definitions, disk-galaxy intrinsic alignments are positive in TNG300 and EAGLE, positive or null in Horizon-AGN, and negative only for reduced shapes at z=1 with |v/σ| disk selecti...

Tracing Large-Scale Structure Morphology with Multiwavelength Line Intensity Maps
CO(1-0) line intensity maps trace the cosmic web's filaments and sheets more strongly than HI 21-cm maps, and SKA2-Mid could recover this structure at z~1.4.

The Concordance of Weak Lensing and Escape Velocity Mass Estimates for Galaxy Clusters
A revised escape velocity mass estimator yields weak lensing and escape masses for 46 clusters that agree within 0.02 dex, with a correlation of 0.68.

Missing baryons recovered: a measurement of the gas fraction in galaxies and groups with the kinematic Sunyaev-Zel'dovich effect and CMB lensing
CMB lensing mass calibration of DESI galaxies, combined with kSZ gas profiles, measures gas fractions that reach the cosmic baryon fraction at large radii but drop to about 30 percent near the virial radius.

Baryonic Feedback across Halo Mass: Impact on the Matter Power Spectrum
Group-scale halos (M200m ~ 10^13-10^14 Msun) drive most of the baryonic suppression of small-scale matter clustering, contributing about 10 of the ~20% total reduction in power.
