An Intermediate Mass Black Hole Hidden Behind Thick Obscuration

Kavli Affiliate: Claudio Ricci | First 5 Authors: Peter G. Boorman, Daniel Stern, Roberto J. Assef, Abhijeet Borkar, Murray Brightman | Summary: Recent models suggest approximately half of all accreting supermassive black holes (SMBHs; $M_{rm BH}$ $gtrsim$ 10$^{5}$ M$_{odot}$) are expected to undergo intense growth phases behind Compton-thick ($N_{rm H}$ $>$ 1.5 $times$ 10$^{24}$ cm$^{-2}$) […]

The NuSTAR Local AGN $N_{rm H}$ Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe

Kavli Affiliate: Claudio Ricci | First 5 Authors: Peter G. Boorman, Poshak Gandhi, Johannes Buchner, Daniel Stern, Claudio Ricci | Summary: Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compton-thick gas column densities of $N_{rm H}$ $>$ […]

Mind the kinematics simulation of planet-disk interactions: time evolution and numerical resolution

Kavli Affiliate: Ruobing Dong | First 5 Authors: Kan Chen, Ruobing Dong, , , | Summary: Planet-disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated. To explore this, we conduct 3D hydrodynamic simulations using the code FARGO3D to study […]
