Discovery of dual “little red dots” indicates excess clustering on kilo-parsec scales

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku, Junya Arita, Hollis B. Akins | Summary: “Little Red Dots” (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST). They are characterized by a red color in the rest-frame optical band, compact morphology, […]

Algorithmic Strategies for Sustainable Reuse of Neural Network Accelerators with Permanent Faults

Kavli Affiliate: Ke Wang | First 5 Authors: Youssef A. Ait Alama, Sampada Sakpal, Ke Wang, Razvan Bunescu, Avinash Karanth | Summary: Hardware failures are a growing challenge for machine learning accelerators, many of which are based on systolic arrays. When a permanent hardware failure occurs in a systolic array, existing solutions include localizing and […]

X-ray properties of coronal emission in radio quiet Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Sibasish Laha, Claudio Ricci, John C. Mather, Ehud Behar, Luigi C. Gallo | Summary: Active galactic nuclei (AGN) are powerful sources of panchromatic radiation. All AGN emit in X-rays, contributing around $sim 5-10%$ of the AGN bolometric luminosity. The X-ray emitting region, popularly known as the corona, […]

On the Relation between the Inclination Angle of the Accretion Disk and the Broad-line Region in Active Galactic Nuclei

Kavli Affiliate: Luis C. Ho | First 5 Authors: Rong Du, Luis C. Ho, Yuanze Ding, Ruancun Li, | Summary: Models of active galactic nuclei often invoke a close physical association between the broad-line region and the accretion disk. We evaluate this theoretical expectation by investigating the relationship between the inclination angle of the BLR […]

Meissner Effect and Nonreciprocal Charge Transport in Non-Topological 1T-CrTe2/FeTe Heterostructures

Kavli Affiliate: Ke Wang | First 5 Authors: Zi-Jie Yan, Zi-Jie Yan, , , | Summary: Interface-induced superconductivity has recently been achieved by stacking a magnetic topological insulator layer on an antiferromagnetic FeTe layer. However, the mechanism driving this emergent superconductivity remains unclear. Here, we employ molecular beam epitaxy to grow a 1T-CrTe2 layer, a […]

Dynamical evolution of massless particles in star clusters with NBODY6++GPU-MASSLESS: I. Free-floating MLPs

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Flammini Dotti, M. B. N. Kouwenhoven, Peter Berczik, Qi Shu, Rainer Spurzem | Summary: Context. Low-mass bodies, such as comets, asteroids, planetesimals, and free-floating planets, are continuously injected into the intra-cluster environment after expulsion from their host planetary systems. These can be modeled as massless particles […]

MoDULA: Mixture of Domain-Specific and Universal LoRA for Multi-Task Learning

Kavli Affiliate: Ran Wang | First 5 Authors: Yufei Ma, Zihan Liang, Huangyu Dai, Ben Chen, Dehong Gao | Summary: The growing demand for larger-scale models in the development of textbf{L}arge textbf{L}anguage textbf{M}odels (LLMs) poses challenges for efficient training within limited computational resources. Traditional fine-tuning methods often exhibit instability in multi-task learning and rely heavily […]
