Studying Gamma‐ray Blazars With The GLAST‐LAT

Thanks to its sensitivity, the GLAST LAT should detect many more (upwards of a thousand) gamma‐ray blazars than currently known. This large blazar sample will enable detailed population studies to be carried out. Moreover, the LAT large field‐of‐view combined with the scanning mode will provide a very uniform exposure over the sky, allowing a constant monitoring of all detected blazars and flare alerts to be issued. Major specific issues regarding the blazar phenomenon that the LAT data should shed light on thanks to these capabilities are discussed, as well as the different approaches foreseen to address them. The associated data required in other bands, to be collected in contemporaneous/simultaneous multiwavelength campaigns are mentioned as well.
