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.
Mid-infrared lines near Sgr A* exhibit no detectable variability during flares, because light-crossing and recombination timescales in the extended gas suppress responses, so the lines cannot constrain instantaneous UV flux.
GRRT simulations show that raising the dilaton parameter shrinks the bright ring while increasing its width and brightness, disk thickness reduces diameter and width with weaker brightness impact, and both affect allowed ranges versus EHT Sgr A* data and the polarization coefficient beta2.

Bright ring features and polarization structures in Kerr-Sen black hole images illuminated by radiatively inefficient accretion flows
GRRT simulations show that raising the dilaton parameter shrinks the bright ring while increasing its width and brightness, disk thickness reduces diameter and width with weaker brightness impact, and both affect allowed ranges versus EHT Sgr A* data and the polarization coefficient beta2.
