New publicly available X-ray table models RXToPo and RXagn1 with realistic AGN geometries (torus, polar cone, disk, BLR) generated via RefleX and tested on NGC 424.
MHD collapse simulations define an Envelope-Disk Transition Zone (ENDTRANZ) where a jump in the j-r profile occurs due to positive gravitational torques, with a corresponding jump detected in ALMA observations of L1527 IRS.
Self-gravitating disks heated by stars reach a universal optical effective temperature of 4000-4500 K independent of accretion rate, black hole mass, and viscosity, explaining Little Red Dots.
Optical continuum lags in NGC 4395 remain stable at 5-15 minutes over multi-year baselines with negligible diffuse continuum contribution.
Cold compact circumbinary rings evolve into highly eccentric disks with suppressed accretion and dominant variability at ~0.1 times the binary orbital frequency via a stream impact mechanism.
VLBA multi-frequency imaging reveals a relativistic, well-collimated jet of ~745 pc in a z=3.4 super-Eddington radio-loud quasar, distinct from low-redshift analogues.
Seyfert galaxy slab coronae show a nearly constant Compton y-parameter of 0.414, implying regulation by slab radiative equilibrium.
Larger black holes in TDEs accrete more material and launch faster winds, with unbound mildly relativistic winds for higher viscosity parameters and bound convective outflows for lower ones.
Realistic black hole dynamics in Astrid reduce baryonic suppression of the matter power spectrum at low redshifts compared to repositioning schemes used in other simulations.
Thermal instability triggers cyclic MRI activity in protoplanetary disks, enabling dust self-accumulation and planetesimal formation near 1 au with enough mass for multiple super-Earths.
Radiative transfer modeling of protostellar ices shows absorption originates mainly from 1000-2000 au at the cavity-envelope transition, with apparent CO2/H2O and CO/H2O ratios potentially underestimated due to line-of-sight effects.
Elliptical BLR geometries cause the virial factor f to vary by over an order of magnitude and induce ~0.18 dex scatter in the R-L relation, challenging attributions of RM uncertainties to non-virial motions or radiation pressure.
A 2D Monte Carlo dust evolution simulation shows that a planet-induced pressure bump reproduces the observed compositions and formation ages of carbonaceous chondrites, implying formation in a single long-lived dust trap outside Jupiter's orbit.
A new observable signature from frame-dragging processes near spinning black holes enables testing Einstein gravity and spin measurement via X-ray polarimetry.
Multi-wavelength data on V1094 Sco support a hybrid origin for its ring-gap structures consisting of planet-disk interaction at ~100 au and secular gravitational instability at 170-230 au in a low-turbulence disk.
Reconnection in transrelativistic AGN coronae can energize protons to tens of PeV, producing a neutrino spectrum consistent with NGC 1068 observations without tuning the proton spectral slope.
EP J174942.2-384834 is classified as a very faint X-ray transient black hole candidate based on its hard X-ray spectra, optical/UV brightening correlated with X-rays, and lack of radio emission.
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.
Disk formation simulations reproduce carbonaceous chondrule oxygen isotopes with moderate radial infall or ice-depleted parental clouds, but ordinary chondrules inside the snow line remain difficult to explain under the modeled conditions.
General-relativistic ray-tracing shows that non-flat accretion disk geometries systematically bias iron Kα-derived black hole spin, coronal height, and inclination estimates when fit with flat-disk models.
Turbulent infall onto class 0 disks sublimates prior CAIs and allows re-condensation during cooling, explaining their brief 100 kyr formation episode.
Turbulent torques modeled as a Gaussian around the linear torque can push gas-induced dephasing in LISA EMRIs above the detection threshold for Eddington ratios above 0.3 and sufficient turbulence strength.
XRISM measurements indicate turbulent dissipation from jets struggles to balance cooling in cluster atmospheres except possibly in limited inner regions of systems like Hydra A.
