Summary: TEHRAN (FNA)- New research has provided a deeper insight into emission line
galaxies, used in several ongoing and upcoming surveys, to help us further understand the composition and fate of the universe.
Indian Institute of Astrophysics (IIA), Bengaluru is the lead institute for the development of Visible Emission Line
Coronagraph (VELC) and Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune is developing the Solar Ultraviolet Imager (SUIT) payload for Aditya-L1 mission.
For emission line
data, standard AnalaR grade salts of lanthanides were used.
This research is funded by a National Science Foundation Major Research Instrumentation grant to enable coronal emission line
observations during the 2017 Great American Solar Eclipse.
Harkness for the first time obtained the spectrum of the solar corona at the occasion of a solar eclipse in North America in 1869, and discovered an emission line
emitted by the corona at a wavelength of 530.

The researchers have used the spatial and velocity information provided by this data to create the first high-resolution, fully 3-D model of the Homunculus Nebula and the new model contains none of the assumptions about the cloud's symmetry found in previous studies, which was developed using only a single emission line
of near-infrared light emitted by molecular hydrogen gas.

It is detected in nearly all galaxies that are seen from a time more than 1,000,000,000 years from the Big Bang, but getting closer than that, the hydrogen emission line
, for some reason, becomes increasingly difficult to see.
H-Alpha light is a spectral line centred on 656nm, and although it is the strongest emission line
of ionised hydrogen, our eyes are not very sensitive to the deep red.
A USB-powered Hg/Ne/Ar emission line
source, available separately, works seamlessly with proprietary hardware and software to ensure high calibration accuracy.
Gas tightly bound to an ejected black hole would stay with the hole and rotate rapidly, producing a broad emission line
showing up as a fat rather than narrow peak.
