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

The most luminous, merger-free AGN show only marginal correlation with bar presence

The role of large-scale bars in the fuelling of active galactic nuclei (AGN) is still debated, even as evidence mounts that black hole growth in the absence of galaxy mergers cumulatively dominated and may substantially influence disc (i.e., merger-f

Galaxy Zoo: Kinematics of strongly and weakly barred galaxies

Autor: Géron, Tobias, Smethurst, Rebecca J., Lintott, Chris, Kruk, Sandor, Masters, Karen L., Simmons, Brooke, Mantha, Kameswara Bharadwaj, Walmsley, Mike, Garma-Oehmichen, L., Drory, Niv, Lane, Richard R.

We study the bar pattern speeds and corotation radii of 225 barred galaxies, using IFU data from MaNGA and the Tremaine-Weinberg method. Our sample, which is divided between strongly and weakly barred galaxies identified via Galaxy Zoo, is the larges

Supermassive black holes in merger-free galaxies have higher spins which are preferentially aligned with their host galaxy

Autor: Beckmann, R. S., Smethurst, R. J., Simmons, B. D., Coil, A., Dubois, Y., Garland, I. L., Lintott, C. J., Martin, G., Peirani, S., Pichon, C.

Here we use the Horizon-AGN simulation to test whether the spins of SMBHs in merger-free galaxies are higher. We select samples using an observationally motivated bulge-to-total mass ratio of < 0.1, along with two simulation motivated thresholds sele
