The Caltech comb
produces spectral lines in the infrared, making it ideal for studying red dwarf stars, the most common stars in the Milky Way.
Argus + will routinely
produce spectral line maps of key species such as CO, HCN, and HCO + with a spatial dynamic range (map area / pixel size) of 104 to 105.
Not exact matches
But Kusenko says the observation will be difficult to interpret: «The problem is to distinguish this [
spectral]
line from all sorts of ordinary
lines produced by gas in the cluster.»
ALMA creates both a visual picture and a spectrum for every pixel of its images,
producing tens of thousands of
spectral lines in every field of view it observes.
The scientists were thus able to transfer the genetic information from the known fluorescent protein eqFP615 into the DT40 chicken B cell
line in order to
produce protein variants of the new infrared marker Amrose with different
spectral properties.
When hydrogen gas is heated by the ultraviolet emissions of new stars, it
produces a
spectral signature called the Lyman - alpha
line.
The Argus millimeter - wave camera on the GBT
produces data cubes of the emission from
spectral lines with high
spectral and spatial resolution.
Magnetic transients have traditionally been explained as artifacts
produced when flare emission contaminates the
spectral line profile, leading to false reversals of the Stokes V profile.
I also understand to about the same extent, how those
spectral lines can have a «fine structure»
producing several
lines instead of one; due to refinements first proposed by Arnold Sommerfeld and others.
