Speaker: Dr. Lucyna Kedziora-Chudczer
Summary: Most galaxies harbour extremely massive black holes in their inner parts. In some so called Active Galaxies, powerful jets are generated due to accretion of matter onto the central black hole. Many such objects show strong and rapid variability of their light emission, observed across the whole electromagnetic spectrum.
Lucyna will describe what this variability can teach us about the Active Galaxies. Lucyna will also discuss what we can learn about the interstellar and intergalactic medium from observations of quasar variability in radio wavelengths.
