Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: This paper presents a comprehensive study on the asymptotically optimal repair of Reed-Solomon (RS) codes with small sub-packetization, specifically tailored for rack-aware distributed storage systems. Through the utilization of multi-base expansion, we introduce a novel approach that leverages monomials […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Benny Trakhtenbrot, Benny Trakhtenbrot, , , | Summary: We use the narrow [Ne v] $lambda$3427 emission line detected in the recently published JWST spectra of two galaxies, at z = 6.9 and 5.6, to study the key properties of the active galactic nuclei (AGN) and the supermassive […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: , , , , | Summary: We present a detailed analysis of the most luminous and obscured Active Galactic Nuclei (AGNs) detected in the ultra-hard X-ray band (14-195 keV) by Swift/BAT. Our sample comprises 21 X-ray luminous (log $L_X/rm erg,s^-1>44.6$, 2-10 keV) AGNs at $z<0.6$, optically classified […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Xiaojing Lin, Xiaojing Lin, , , | Summary: JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0.1-0.2$, initially selected from the SDSS database, with follow-up optical/near-IR spectroscopy […]

Kavli Affiliate: Ke Wang | First 5 Authors: Xiao-Xiong Zeng, Xiao-Xiong Zeng, , , | Summary: In this paper, we investigate the power and efficiency of energy extraction through magnetic reconnection in the Kerr-Sen-AdS$_4$ black hole, with a primary focus on both the circular orbit and plunging region. We plot the allowed regions for energy […]

Kavli Affiliate: Ke Wang | First 5 Authors: Amirhossein Ansari, Amirhossein Ansari, , , | Summary: Recent advancements in Vision-Language Models like CLIP have enabled zero-shot OOD detection by leveraging both image and textual label information. Among these, negative label-based methods such as NegLabel and CSP have shown promising results by utilizing a lexicon of […]
