Galaxy Zoo DESI: large-scale bars as a secular mechanism for triggering AGN

Autor: Garland, Izzy L., Walmsley, Mike, Silcock, Maddie S., Potts, Leah M., Smith, Josh, Simmons, Brooke D., Lintott, Chris J., Smethurst, Rebecca J., Dawson, James M., Keel, William C., Kruk, Sandor, Mantha, Kameswara Bharadwaj, Masters, Karen L., O'Ryan, David, Popp, Jürgen J., Thorne, Matthew R.

Despite the evidence that supermassive black holes (SMBHs) co-evolve with their host galaxy, and that most of the growth of these SMBHs occurs via merger-free processes, the underlying mechanisms which drive this secular co-evolution are poorly under
