How Solar Soft X-Ray Irradiance Is Affected by the Size of Field of View

The Astrophysical Journal, 2023
Soft X-ray images of the Sun obtained with multiple broadband filters provide a simple and useful method to calculate averaged coronal temperature and emission measure, from which we can further calculate solar X-ray irradiance in physical units, e.g ...

The reversal of the Sun’s magnetic field in cycle 24

Solar-Terrestrial Physics, 2016
Analysis of synoptic data from the Vector Spectromagnetograph (VSM) of the Synoptic Optical Long-term Investigations of the Sun (SOLIS) and the NASA/NSO Spectromagnetograph (SPM) at the NSO/Kitt Peak Vacuum Telescope facility shows that the reversals of ...

Two Massive, Compact, and Dust-obscured Candidate z ≃ 8 Galaxies Discovered by JWST

The Astrophysical Journal, 2023
We present a search for extremely red, dust-obscured, z > 7 galaxies with JWST/NIRCam+MIRI imaging over the first 20 arcmin ^2 of publicly available Cycle 1 data from the COSMOS-Web, CEERS, and PRIMER surveys.

The presence of a systematic error in SDO/HMI data

Solar-Terrestrial Physics, 2018
In this paper, we came to the conclusion that there is a systematic error in SDO/HMI (Helioseismic and Magnetic Imager aboard the Solar Dynamics Observatory) vector magnetic data, which reveals itself in a deviation from the radial direction of the knot ...

LINC00355 promoted the progression of lung squamous cell carcinoma through regulating the miR-466/LYAR axis

Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas, 2020
LINC00355 has been reported aberrantly over-expressed and associated with poor prognosis in various types of cancer. However, reports regarding the effect of LINC00355 on lung squamous cell carcinoma (SCC) are rare.

Investigating seasonal features of electron temperature enhancement regions in the subauroral ionosphere

Solar-Terrestrial Physics, 2019
The electron temperature enhancement is known to occur in the main ionospheric trough during geomagnetic disturbances. In this paper, we study fea-tures of the formation of the electron temperature (Te) enhancement in the subauroral ionosphere by ...
