29. Photometric redshifts for AGN

Raphael Shirley

25/07/2024, 09:30

Photometric redshifts play a crucial role in all areas of extragalactic astronomy. Applying standard methods to AGN has shown there are specific challenges due to the features of typical spectral energy distributions. In this talk I will present an overview of the current state of the art and talk about prospects for future development. Machine learning methods applied to both catalogue and...

23. CONSTRAINING PHOTOMETRIC REDSHIFTS OF QUASARS USING VARIABILITY

Quasars are known for their intrinsic variability which is stochastic at several time scales. Studying these objects in very large samples helps to improve the statistics and allows systematic studies of the time scales of variability and their relation with the physical mechanisms driving these flux changes. With the upcoming large time domain photometric surveys such as the Vera C. Rubin...

28. Photometric redshifts for high-z quasars in the era of LSST

Though only making up 0.1% of all known quasars, high redshift (z>5) quasars are vital to understanding the formation and evolution of galaxies, the growth of supermassive black holes, and the changing ionisation state of the early Universe. The Vera Rubin Observatory Legacy Survey of Space and Time (LSST) is expected to increase the number of known high-z quasars from ~1000 to 10,000,...
