FIRE-2 simulations show per-galaxy tidal disruption rates peak near z=2.5 at 4e-4 per year, correlate with SFR and central density, and remain high in satellite galaxies at early times.
Primordial black holes captured by stars lead to either quiet consumption or explosive disruption via disk formation, producing transients and high-spin remnants with potentially observable event rates.
Discovery of the highest-redshift non-jetted TDE at z=1.037 with constant ~19,000 K blackbody temperature and peak luminosity ~8e44 erg/s.
J1105+1452 transitioned to a megahertz peaked-spectrum source with a new compact jet of radius ~0.68 pc, apparent velocity ~0.64c, and Doppler factor ~12, while X-ray emission stayed disk-corona dominated.
SPH simulations of zero-energy partial TDEs find fallback ~t^{-9/4}, optical luminosities 10^{42-44} erg/s at 10^4 K and radii 10-100 au, indicating many detected TDEs may be partial rather than full.
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.
Machine learning on precursor emission in 366 GRBs yields a simple prompt-only index EPI that separates merger-driven from collapsar-driven bursts at a threshold of 6.2.
EP251023a is a new extragalactic fast X-ray transient whose optical light curve is interpreted as a rare magnetar-powered internal plateau with derived upper limits on spin period and magnetic field.
First blind optical identification of a z=0.153 sub-luminous GRB afterglow with Ic-BL SN, yielding a volumetric rate consistent with on-axis high-luminosity long GRBs.
The curved spectrum of the young pulsar halo LHAASO J0248+6021 is explained by a time-dependent energy-loss bump in the electron spectrum that remains close to the cutoff, unifying it with the shifted bump observed in the older Geminga halo.
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.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.
M-EPDet reports 98.31% recall for genuine sources while rejecting 92.99% of instrumental artifacts and 98.18% of cosmic ray events, reducing candidate volume by 99.25% in EP-WXT on-orbit data.
Forecasts show that ~66 optical GRBs can achieve σ_w ≈ 0.47 in wCDM using Dainotti relations, matching Planck precision and enabling independent high-redshift tests of dark energy.
Discovery of an eclipsing neutron star LMXB with clocked bursts, orbital period 6.483 hr, companion mass 0.6-0.8 Msun, and helium burst indications from energy ratio 120-130.
The paper provides observing strategies, detection forecasts, and predictions for using SKA and VLBI to study radio emission from tidal disruption events around supermassive black holes.
SKA+VLBI will deliver microarcsecond astrometry, polarimetry, and rapid multi-frequency imaging to track jets and accretion in X-ray binaries on AU scales.
Overview of SKAO's role in radio follow-up of GW events, GRB afterglows, and kilonovae for system characterization and population studies.
