A 25-year Chandra catalog of 100 Sgr A* X-ray flares confirms that brighter flares are spectrally harder and strengthens prior correlations with duration and fluence.
30-year kinematic monitoring of 27 Galactic center Wolf-Rayet stars identifies five binary candidates and infers a binary fraction of 0.56 ± 0.18.
Black-bounce solutions are obtained from a self-interacting 3-form field in GR plus scalar, producing two families that are globally regular with asymmetric horizons and different scalar behaviors.
DAMPE independently detects the Fermi bubbles at 26 sigma and the Galactic center GeV excess at 7 sigma, with the excess spectrum and morphology matching Fermi-LAT and fitting a 50 GeV dark matter particle annihilating to b quarks.
MOG produces distinct orbital precession and sky-projected deviations for S-stars that grow with the parameter α and can resemble dark matter effects while remaining testable against GR.
Synthetic EHT data from semi-analytic jet models show that the 2022 array configuration enables robust recovery of faint horizon-scale jet emission in M87* when jet intensity exceeds a determined lower limit.
EHT angular diameter data yield upper bounds on the holonomy correction b (e.g., b ≤ 0.1319M at a=0 for M87*) showing nonzero b remains consistent with observations for RHCBH spacetimes.
New VLBA parallaxes for four masers refine the Perseus arm position and pitch angle in the first Galactic quadrant, with extrapolation showing intersection with the Sagittarius arm at 200° azimuth and 5.6 kpc radius.
