Calibration of Electrically Short Antennas Using the l = 2 Spherical Harmonic Expansion Coefficients of the Radio Brightness Distribution on the Sky Between 0.5 and 6.8 MHz

Radio Science, Volume 60, Issue 8, August 2025.
Abstract A space‐borne radio‐frequency antenna is typically located in the vicinity of a conductive spacecraft body that influences its beam. Also, at wavelengths that greatly exceed the sizes of such an antenna and spacecraft, the antenna is expected to have the beam of an equivalent short dipole.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

An All-sky 3D Dust Map Based on Gaia and LAMOST

The Astrophysical Journal Supplement Series
We present a comprehensive 3D dust-reddening map covering the entire Milky Way, constructed by combining reddening estimates based on Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST) low-resolution spectra ( E ( B  −  V ) _LAMOST ) with ...

Interstellar Extinction of Planetary Nebulae [PDF]

Symposium - International Astronomical Union, 1993
We have compared the extinction of planetary nebulae (PN) as derived from the Balmer decrement and from the ratio of radio to Hβ fluxes.

Microalgae: A Solution for Food Security and Multiplanetary Farming

Food Frontiers, Volume 6, Issue 3, Page 1242-1251, May 2025.
ABSTRACT Human civilization is threatened by food insecurity and habitat loss owing to the cumulative effects of anthropogenic and natural factors. Thus, increasing food production while using fewer resources and exploring the potential of interstellar migration is essential.

Interstellar Silicon Depletion and the Ultraviolet Extinction

, 2017
Spinning small silicate grains were recently invoked to account for the Galactic foreground anomalous microwave emission. These grains, if present, will absorb starlight in the far ultraviolet (UV).

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST

The Astrophysical Journal Letters
Investigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).
