Convective Magnetic Flux Emergence Simulations from the Deep Solar Interior to the Photosphere: Comprehensive Study of Flux Tube Twist

The Astrophysical Journal
The emergence of magnetic flux from the deep convection zone plays an important role in solar magnetism, such as the generation of active regions and triggering of various eruptive phenomena, including jets, flares, and coronal mass ejections.

Quiescent Solar Wind Regions in the Near-Sun Environment: Properties and Radial Evolution

The Astrophysical Journal
Regions of magnetic fields with near-radial, Parker-spiral-like geometry known as quiescent regions have been observed in Parker Solar Probe data. These regions have very low δ B /〈∣ B ∣〉 compared to nonquiescent solar wind at the same heliocentric ...

Superlattice cathodes endow cation and anion co-intercalation for high-energy-density aluminium batteries

Nature Communications
Conventionally, rocking-chair batteries capacity primarily depends on cation shuttling. However, intrinsically high-charge-density metal-ions, such as Al3+, inevitably cause strong Coulombic ion-lattice interactions, resulting in low practical energy ...

Determining the Magnetic Field in the Galactic Plane from New Arecibo Pulsar Faraday Rotation Measurements

The Astrophysical Journal
We develop a new method for studying the Galactic magnetic field along the spiral arms using pulsar Faraday rotation measures (RMs). Our new technique accounts for the dot-product nature of Faraday rotation and also splits the associated path integral ...

Radiative Pressure on Fractal Dust Grains in Oxygen-rich AGB Stars

The Astrophysical Journal
There is still considerable debate on the exact composition of grains formed in the outflows of O-rich, asymptotic giant branch stars. Estimates of the expected condensation distances based on radiative transfer calculations show that iron-free silicates

FAST H i 21 cm Study of Blueberry Galaxies

The Astrophysical Journal Letters
Green Peas (GPs) and blueberry galaxies (BBs) are thought to be local analogs ( z < 0.1) of high redshift Ly α emitters. H i study of these can help us understand the star formation in the primordial Universe.

Simulations of the Collision between a Debris Stream and an Outer Dusty Torus: A Possible Channel for Forming a Fast-rise and Long-delay Radio Outburst in Tidal Disruption Events

The Astrophysical Journal
A geometrically thick dusty torus structure is believed to exist in the nuclear regions of galaxies (especially in active galactic nuclei). The debris stream from a tidal disruption event (TDE) will possibly collide with the dusty torus and produce a ...

Temporal Evolution of a Network Jet’s Physical Properties Inferred from FISS/GST and IRIS Observations

The Astrophysical Journal
Small-scale jets, such as chromospheric and transition region (TR) network jets, are of great interest regarding coronal heating and solar wind acceleration. Spectroscopic analysis based on multiple spectral lines with different formation temperatures is

Multiwavelength Long-term Studies of Radio Galaxy NGC 1275

The Astrophysical Journal
It is widely considered that the processes of an interaction between the energy and radiation, which are generated in the active galactic nuclei (AGN) by accretion onto their central massive black hole with the gas in the host galaxy, take a great part ...

A Quasar-anchored Protocluster at z = 6.6 in the ASPIRE Survey. I. Properties of [O iii] Emitters in a 10 Mpc Overdensity Structure

The Astrophysical Journal
A SPectroscopic survey of bIased halos in the Reionization Era is a quasar legacy survey primarily using JWST to target a sample of 25 z  > 6 quasars with NIRCam slitless spectroscopy and imaging. The first study in this series found evidence of a strong
