Rest-frame Ultraviolet Variability of Quasars in the Cosmic Himalayas Overdensity
Some high-redshift overdensities show an enhanced incidence of AGNs, suggesting that large-scale environment may influence supermassive black hole fuelling and triggering. Whether environment also affects AGN variability remains unclear. Using the Cosmic Himalayas (CH), an extreme concentration of 11 type 1 quasars at...
