Active Galactic Nuclei

Active Galactic Nuclei. Very small angular size: point like High luminosity: compared to host galaxies Broad-band continuum emission: radio to TeV Strong emission lines: unlike stars or galaxies Broad lines ( ??/? ~ 0.05) Narrow lines ( ??/? ~ 0.002) Variability: some are highly variable

Searching for pulsars

Searching for pulsars. Radio astronomy at Green Bank. Background. Pulsars are rapidly spinning neutron stars They are slightly more massive than our sun (1.4 Mo), but much smaller (10 to 20 km in diameter) Their discovery came as a surprise to astronomers in the 1960s
