Discovery of magnetic-field-tunable density modulations and spin tilting in a layered altermagnet

Communications Materials
Altermagnets recently emerged as a new class of magnetic materials, arising from specific spin crystal symmetries. They exhibit a spin-polarized electronic band structure similar to ferromagnets, yet possess zero net magnetization, promising exotic ...

Measuring Dwarf Galaxy Intrinsic Abundance Scatter with Mid-resolution Spectroscopic Surveys: Calibrating APOGEE Abundance Errors

The Astrophysical Journal
The first generations of stars left their chemical fingerprints on metal-poor stars in the Milky Way and its surrounding dwarf galaxies. While instantaneous and homogeneous enrichment implies that groups of conatal stars should have the same element ...

Panic at the ISCO: Time-varying Double-peaked Broad Lines from Evolving Accretion Disks Are Common among Optically Variable AGNs

The Astrophysical Journal
About 3%–10% of Type I active galactic nuclei (AGNs) have double-peaked broad Balmer lines in their optical spectra originating from the motion of gas in their accretion disk.

Kinematics and Untwisting Motion of an Intriguing Jet-like Prominence Eruption

The Astrophysical Journal
We aim to investigate the blowout jet-like prominence eruption, which occurred on 2023 October 6, with the help of imaging and spectroscopic observations. Firstly, the prominence rises slowly at a speed of 33 km s ^−1 , followed by a fast rise (i.e., 338
