PPT-Demographics of SDSS Quasars in Two-Dimension

Yue Shen Carnegie Observatories In collaboration with Brandon Kelly UCSB M otivation T he abundance and clustering of quasars are key to understand the evolution of quasarsSMBHs in the hierarchical structure formation paradigm . Lesson Objectives. To appreciate that some galaxies emit far more energy at some wavelengths that can be explained simply in terms of ‘starlight’.. To recall the types of active galaxies.. To show an understanding of the mechanism for producing large quantities of radiation from active galaxies.. Constraining Dark Energy with intermediate-. redshift. probes. Hubert . Lampeitl.

They still really don’t know.. Because of the initial ambiguity surrounding the Quasars they . M87. Hercules A radio jets. Active Galactic Nuclei (AGNs) and Supermassive Black Holes.

VG. So we want a color magnitude diagram for AGN so that by looking at the color of an AGN we can get its luminosity. But AGN have no fusion, why would we expect a color-magnitude relation?. The gas that accretes onto the black hole is still hot and so must follow the Blackbody Radiation law. . . 2016. Lauren Solomon. Manager of Consumer Policy & Programs.
