WebJun 6, 2024 · The recently-discovered Outer Scutum-Centaurus ( OSC) spiral arm is the most distant known arm comprised of molecular gas in the Milky Way, lying about 15 kpc from the center of the Galaxy and warping up to 4 degrees above the Galactic plane at its peak. In this study, we use the VLA radio telescope array to observe 12 HII regions in the OSC ... WebJan 4, 2016 · To answer the OP's query of how to identify the HII regions, first get a .fits file of the galaxy (included in CdC or make one from the ESO Digitized Sky Survey), then display the .fits file and the HII catalogues in a planetarium program (CdC is shown as an example). The image of an individual region can be looked up in

WebThis is in the visible red light spectrum. HII regions are known to have very strong H-Alpha lines, confirming that these transitions do take place quite frequently. Similar to how hydrogen atoms decay into its ground state, other gases in the HII regions will experience the same types of transitions.

The minimum … WebJun 28, 2014 · You probably recall that emission nebulae are commonly referred to as "HII regions". Electrons that have been stripped from the hydrogen atoms can rejoin atoms and resume the process of Balmer decays all over again. This ongoing process is what gives us the reddish-colored nebulae. So that's the technical explanation. You were warned! circumscribing relationship

An H II region or HII region is a region of interstellar atomic hydrogen that is ionized. It is typically in a molecular cloud of partially ionized gas in which star formation has recently taken place, with a size ranging from one to hundreds of light years, and density from a few to about a million particles per cubic … See more The term H II is pronounced "H two" by astronomers. "H" is the chemical symbol for hydrogen, and "II" is the Roman numeral for 2. It is customary in astronomy to use the Roman numeral I for neutral atoms, II for singly … See more The precursor to an H II region is a giant molecular cloud (GMC). A GMC is a cold (10–20 K) and dense cloud consisting mostly of molecular hydrogen. GMCs can exist in a stable state for long periods of time, but shock waves due to supernovae, collisions between … See more Notable Galactic H II regions include the Orion Nebula, the Eta Carinae Nebula, and the Berkeley 59 / Cepheus OB4 Complex. The Orion Nebula, about 500 pc (1,500 light-years) from Earth, is part of OMC-1, a giant molecular cloud that, if visible, would be seen to fill most … See more A few of the brightest H II regions are visible to the naked eye. However, none seem to have been noticed before the advent of the telescope in the early 17th century. Even Galileo did not notice the Orion Nebula when he first observed the star cluster within … See more Stars form in clumps of cool molecular gas that hide the nascent stars. It is only when the radiation pressure from a star drives away its … See more Physical properties H II regions vary greatly in their physical properties. They range in size from so-called ultra-compact (UCHII) regions perhaps only a See more As with planetary nebulae, estimates of the abundance of elements in H II regions are subject to some uncertainty. There are two different ways of determining the abundance of … See more WebBesides the true HII regions, there are also many "misclassifications" in the Sharpless Catalog, such as reflection nebula (often in connection to HII emission nebula), large planetary nebula, supernova remnants, Wolf-Rayet-Bubbles (such as Sh 308 to the right), or the two Maffei galaxies. ...
