Observations of a Possible Transient Magnetically Arrested Accretion State in a Nearby Quasar: OQ208
Brian Punsly, Cormac Reynolds, Paola Marziani +12
OQ208 is a nearby, partially obscured quasar (z=0.077) that is a young, bright, parsec scale radio source. We assemble archival and new high frequency VLBA and VLA observations and…
Investigating the origin of radio emission in candidate super-Eddington accreting black holes
Marie-Lou Gendron-Marsolais, Paola Marziani, Marco Berton +8
Recent works show that the radio power of quasars accreting at very high rates can reach surprisingly high values. These studies suggest that this radio emission might originate fr…
The scaling relations of galaxies with different morphology: comparison among WINGS, MANGA and Illustris data samples
Mauro D'Onofrio, Francesco Brevi, Cesare Chiosi +1
We present a panoramic view of several scaling relations (ScRs) of galaxies of different morphology. The ScRs are obtained from the data of two large surveys (WINGS and MANGA). We…
Monitoring AGNs with H Asymmetry. V. Long-term Variation and Evolution of the Broad H Emission-Line Profiles
Feng-Na Fang, Pu Du, Michael S. Brotherton +40
The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal varia…
Where to search for supermassive binary black holes
Paola Marziani, Edi Bon, Natasa Bon +1
Supermassive binary black holes (SMBBHs) are the anticipated byproducts of galaxy mergers and play a pivotal role in shaping galaxy evolution, gravitational wave emissions, and acc…
The role of dry mergers in shaping the scaling relations of galaxies
Mauro D'Onofrio, Cesare Chiosi, Francesco Brevi
In the context of the hierarchical formation of galaxies, we investigated the role played by mergers in shaping the scaling relations of galaxies, that is the projections of their…
