OPUS: Occupancy Prediction Using a Sparse Set

Kavli Affiliate: Ke Wang | First 5 Authors: Jiabao Wang, Zhaojiang Liu, Qiang Meng, Liujiang Yan, Ke Wang | Summary: Occupancy prediction, aiming at predicting the occupancy status within voxelized 3D environment, is quickly gaining momentum within the autonomous driving community. Mainstream occupancy prediction works first discretize the 3D environment into voxels, then perform classification […]

A Two-zone Accretion Disk in the Changing-look Active Galactic Nucleus 1ES 1927+654: Physical Implications for Tidal Disruption Events and Super-Eddington Accretion

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ruancun Li, Luis C. Ho, Claudio Ricci, Benny Trakhtenbrot, | Summary: The properties of slim accretion disks, while crucial for our understanding of black hole growth, have yet to be studied extensively observationally. We analyze the multi-epoch broad-band spectral energy distribution of the changing-look active galactic […]

Modeling ALMA Observations of the Warped Molecular Gas Disk in the Red Nugget Relic Galaxy NGC 384

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh, Kyle M. Kabasares, Benjamin D. Boizelle | Summary: We present 0$.!!^{primeprime}{22}$-resolution CO(2$-$1) observations of the circumnuclear gas disk in the local compact galaxy NGC 384 with the Atacama Large Millimeter/submillimeter Array (ALMA). While the majority of the disk […]

Massive Star Formation Starts in Sub-virial Dense Clumps Unless Resisted by Strong Magnetic Fields

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Yueluo Wang, Fengwei Xu, , | Summary: The initial conditions are critical for understanding high-mass star formation, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 candidate high-mass starless clumps (HMSCs), here we investigate the dynamical state of […]

Extremely Dense Gas around Little Red Dots and High-redshift AGNs: A Non-stellar Origin of the Balmer Break and Absorption Features

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Roberto Maiolino, , , | Summary: The James Webb Space Telescope (JWST) has uncovered low-luminosity active galactic nuclei (AGNs) at high redshifts of $zgtrsim 4-7$, powered by accreting black holes (BHs) with masses of $sim 10^{6-8}~M_odot$. These AGN populations are considered crucial for understanding early […]

Low-energy critical behavior in two-dimensional tilted semi-Dirac semimetals driven by fermion-fermion interactions

Kavli Affiliate: Jing Wang | First 5 Authors: Wen Liu, Wen-Hao Bian, Xiao-Zhuo Chu, Jing Wang, | Summary: Employing the renormalization group approach, we carefully investigate the critical behavior of two-dimensional tilted semi-Dirac semimetals induced by the fermion-fermion interactions in the low-energy regime. After incorporating all one-loop corrections, we derive the coupled RG equations of […]

No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time

Kavli Affiliate: Linhua Jiang | First 5 Authors: Danyang Jiang, Masafusa Onoue, Linhua Jiang, Samuel Lai, Eduardo Banados | Summary: The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expected different enrichment […]

Two Channels of Metal-Rich Compact Stellar System Formation: Starbursts Under High Ram Pressure vs. Tidal Stripping

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yuan Bian, Min Du, Victor P. Debattista, Dylan Nelson, Mark A. Norris | Summary: Most galaxies follow well-defined scaling relations of metallicity and stellar mass; however, some outliers at the low mass end of the observed galaxy population exhibit unusually high metallicity for their mass. Understanding […]

A novel standard candle: collapsing axion stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Haoran Di, Lijing Shao, Zhu Yi, Shi-Bei Kong, | Summary: The Hubble constant, $H_0$, is a crucial parameter in cosmology. However, various cosmic observations have produced differing posterior values for $H_0$, resulting in what is referred to as the $H_0$ tension. To resolve this discrepancy, utilizing other […]
