DMSC: Dynamic Multi-Scale Coordination Framework for Time Series Forecasting

Kavli Affiliate: Zhuo Li | First 5 Authors: Haonan Yang, Haonan Yang, , , | Summary: Time Series Forecasting (TSF) faces persistent challenges in modeling intricate temporal dependencies across different scales. Despite recent advances leveraging different decomposition operations and novel architectures based on CNN, MLP or Transformer, existing methods still struggle with static decomposition strategies, […]

Theoretical Diagnostics for the Physical Conditions in Active Galactic Nuclei under the View of JWST

Kavli Affiliate: Claudio Ricci | First 5 Authors: Lulu Zhang, Lulu Zhang, , , | Summary: With excellent spectral and angular resolutions and, especially, sensitivity, the JWST allows us to observe infrared emission lines that were previously inaccessible or barely accessible. These emission lines are promising for evaluating the physical conditions in different galaxies. Based […]

Revisiting the Proper Motions of M31 and M33 Using Massive Supergiant Stars with Gaia DR3

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Hao Wu, , , | Summary: The proper motions (PMs) of M31 and M33 are key to understanding the Local Group’s dynamical evolution. However, measurement discrepancies between Gaia blue and red samples, regarding whether the transverse velocity is remarkable, introduce significant ambiguity. In this work, […]

Mapping the Distant and Metal-Poor Milky Way with SDSS-V

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Vedant Chandra, Vedant Chandra, , , | Summary: The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way’s stellar halo. We describe the stellar parameter pipeline for the SDSS-V halo survey, which simultaneously models spectra, broadband photometry, […]

The Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial $B$-modes

Kavli Affiliate: Susan E. Clark | First 5 Authors: Yiqi Liu, Yiqi Liu, , , | Summary: We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, $r$, in the context of the Simons Observatory, using a cross-spectrum component separation analysis. Employing a suite of simulations with realistic Galactic dust emission, we […]

Discovery of a Little Red Dot candidate at $zgtrsim10$ in COSMOS-Web based on MIRI-NIRCam selection

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Takumi S. Tanaka, Takumi S. Tanaka, , , | Summary: JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is crucial for understanding the formation of […]
