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 $N_{rm H}$ $>$ […]

Tracking the jet-like corona of black hole Swift J1727.8-1613 during a flare state through Type-C quasi-periodic oscillations

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jie Liao, Ning Chang, Lang Cui, Pengfei Jiang, Didong Mou | Summary: Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients typically manifest in the low-hard and hard-intermediate states. This study presents a detailed spectral and temporal analysis of the black hole candidate Swift J1727.8-1613 using […]

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 […]

Beyond the Phase Ordering Problem: Finding the Globally Optimal Code w.r.t. Optimization Phases

Kavli Affiliate: Ke Wang | First 5 Authors: Yu Wang, Hongyu Chen, Ke Wang, , | Summary: In this paper, we propose a new concept called textit{semantically equivalence} wrt textit{optimization phases} textit{(sep)}, which defines the set of programs a compiler considers semantically equivalent to the input using a set of optimization phases. We show both […]

Giant and Tunable Bosonic Quantum Interference Induced by Two-Dimensional Metals

Kavli Affiliate: Ke Wang | First 5 Authors: Kunyan Zhang, Rinu Abraham Maniyara, Yuanxi Wang, Arpit Jain, Maxwell T. Wetherington | Summary: Harnessing quantum interference among bosons provides significant opportunities as bosons often carry longer coherence time than fermions. As an example of quantum interference, Fano resonance involving phonons or photons describes the coupling between […]
