Radio Properties of Narrow-Line and Broad-Line Seyfert 1 Galaxies

K. É. Gabányi, S. Komossa, A. Mezősi +2

Narrow-line Seyfert 1 (NLS1) galaxies host active galactic nuclei (AGN) with narrow optical emission lines of the broad-line region. This is often explained with a relatively lower…

Deep Hierarchical Knowledge Loss for Fault Intensity Diagnosis

Yu Sha, Shuiping Gou, Bo Liu +8

Fault intensity diagnosis (FID) plays a pivotal role in intelligent manufacturing while neglecting dependencies among target classes hinders its practical deployment. This paper in…

Exploring giant barium stars: ratio and elemental abundances of carbon, nitrogen, and oxygen

M. P. Roriz, N. A. Drake, N. Holanda +4

Barium (Ba) stars belong to binary systems that underwent mass transfer events. As a consequence, their envelopes were enriched with material synthesized in the interiors of their…

A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk

Julie Imig, Jon A. Holtzman, Gail Zasowski +23

The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…

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

Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28

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…

Reconstructing the Milky Way chemical map with Galactic Chemical Evolution tool OMEGA+ from SDSS-MWM

Viola Hegedűs, Szabolcs Mészáros, Blanka Világos +4

We obtain two-infall galactic chemical evolution (GCE) models simulating the chemical evolution of the Milky Way as constrained by a golden sample of stellar abundances o…
