SIMULATION STUDY OF THE ENERGETIC NEUTRAL ATOM (ENA) IMAGING MONITORING OF THE GEOMAGNETOSPHERE ON A LUNAR BASE

open access: yesSolar-Terrestrial Physics, 2021
Since the moon’s revolution cycle is exactly the same as its rotation cycle, we can only see the moon always facing Earth in the same direction. Based on the clean particle radiation environment of the moon, a neutral atomic telemetry base station could ...

The GBT Diffuse Ionized Gas Survey (GDIGS): Discrete Sources

open access: yesThe Astrophysical Journal, 2023
The Green Bank Telescope Diffuse Ionized Gas Survey (GDIGS) traces ionized gas in the Galactic midplane by observing radio recombination line (RRL) emission from 4 to 8 GHz. The nominal survey zone is 32.°3 > ℓ > −5°, ∣ b ∣ < 0.°5. Here, we analyze GDIGS

On the Formation of Double Neutron Stars in the Milky Way: Influence of Key Parameters

open access: yesThe Astrophysical Journal
The detection of gravitational wave events has stimulated theoretical modeling of the formation and evolution of double compact objects (DCOs). However, even for the most studied isolated binary evolution channel, there exist large uncertainties in the ...

On the Existence, Rareness, and Uniqueness of Quenched H i-rich Galaxies in the Local Universe

open access: yesThe Astrophysical Journal
Using data from ALFALFA, xGASS, H i -MaNGA, and the Sloan Digital Sky Survey (SDSS), we identify a sample of 47 “red but H i -rich” (RR) galaxies with near-UV (NUV) − r > 5 and unusually high H i -to-stellar mass ratios. We compare the optical properties

Yet Another Sunshine Mystery: Unexpected Asymmetry in GeV Emission from the Solar Disk

open access: yesThe Astrophysical Journal
The Sun is one of the most luminous γ -ray sources in the sky and continues to challenge our understanding of its high-energy emission mechanisms. This study provides an in-depth investigation of the solar disk γ -ray emission, using data from the Fermi ...

Detection of Pairwise Kinetic Sunyaev–Zel’dovich Effect with DESI Galaxy Groups and Planck in Fourier Space

open access: yesThe Astrophysical Journal Supplement Series
We report a ∼5.2 σ detection of the kinetic Sunyaev–Zel’dovich (kSZ) effect in Fourier space, by combining the DESI galaxy groups and the Planck data.

A Fast Radio Burst in a Compact Galaxy Group at z ∼ 1

open access: yesThe Astrophysical Journal Letters
FRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations of the field of FRB 20220610A. The imaging reveals seven extended sources, one of

Radial Evolution of the Near-Sun Solar Wind: Parker Solar Probe Observations

open access: yesThe Astrophysical Journal Letters
A statistical study of the radial evolution of the solar wind within 0.3 au is shown in this Letter based on Parker Solar Probe observations. We show the radial distribution of the main solar wind parameters, including the solar wind speed V _sw ...
