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 […]

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 […]

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 […]

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 […]

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 […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Masafusa Onoue, Masafusa Onoue, , , | Summary: Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec rest-frame optical spectra and NIRCam imaging from JWST of two galaxies at z>6, […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Anthony J. Taylor, Steven L. Finkelstein, Dale D. Kocevski, Junehyoung Jeon, Volker Bromm | Summary: We present a sample of 50 H-alpha detected broad-line active galactic nuclei (BLAGN) at redshifts 3.5<z<6.8 using data from the CEERS and RUBIES surveys. We select these sources directly from JWST/NIRSpec G395M/F290LP […]

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 […]
