Dissecting the Nuclear Structure of NGC 5548 with XRISM. I. Physical Properties of the Highly Ionized Outflows

01/09/2026 - High-Energy

We present a detailed spectral analysis of an X-Ray Imaging and Spectroscopy Mission (XRISM) observation of the prototypical Seyfert 1 galaxy NGC 5548. XRISM’s Resolve microcalorimeter reveals, for the first time, highly ionized outflows in this active galactic nucleus (AGN) through the detection of Fe XXV and Fe XXVI absorption lines in the Fe K…

Super-resolving Herschel: A deep-learning-based deconvolution and denoising technique: I. First application at 500 µm in the COSMOS field

01/09/2026 - Low-Energy

Aims. Dusty star-forming galaxies (DSFGs) dominate the far-infrared (FIR) and sub-millimetre (sub-mm) number counts, but singledish surveys at these wavelengths suffer from poor angular resolution, making identifications of multi-wavelength counterparts difficult. Prior driven deblending techniques require extensive fine-tuning and struggle to process large fields. This work aims to develop a fast and reliable deep-learning-based deconvolution…

Polarized reflectance in China from DPC-2/GF-5(02) polarimetric satellite measurements: dataset and model inter-comparison

01/09/2026 - Aerosols and clouds

The Bidirectional Polarization Distribution Function (BPDF) is essential in quantitative remote sensing, particularly for understanding the anisotropy of land surface polarization properties. The widely-used BRDF-BPDF dataset claimed to not corrected for aerosol scattering, which lay a hidden problem for BPDF modeling. In our work, we conducted aerosol correction based on Chinese polarimetric data DPC-2/GF-5(02), and…
