[1902.01408] Metallicity calibrations for diffuse ionised gas and …
2019年2月4日 · Using integral field spectroscopic data of 24 nearby spiral galaxies obtained with the Multi-Unit Spectroscopic Explorer (MUSE), we derive empirical calibrations to determine …
The origin of the H$α$ line profiles in simulated disc galaxies
2024年1月8日 · We investigate the relative contribution of diffuse and dense Hα emitting gas, corresponding to DIG (ρ ≲ 0.1 cm−3, T ∼ 8 000 K) and HII regions (ρ ≳ 10 cm−3, T ∼ 10 000 …
diffuse ionized gas. The Ha/FUV ratio is higher in HII regions than in the DIG, possibly indicating that an older population ionizes the DIG. The broad-band colors support this conclusion. The …
The Hardness of the Radiation in the Warm Ionized Medium
Here, we use Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS) data to investigate the ionic abundance ratio y + = He + /H + in HII regions and the DIG. GDIGS was …
The origin of the Hα line profiles in simulated disc galaxies
2024年9月9日 · We investigate the relative contribution of diffuse and dense Hα emitting gas, corresponding to diffuse ionised gas (DIG; ρ ≲ 0.1 cm −3, T ∼ 8 000 K) and HII regions (ρ ≳ …
(PDF) The diffuse ionized gas (DIG) in star-forming ... - ResearchGate
2021年9月6日 · The Diffuse Ionized Gas (DIG) contributes to the nebular emission of galaxies, resulting in emission line flux ratios that can be significantly different from those...
The nature of diffuse ionised gas in star-forming galaxies
2024年5月22日 · The state of the DIG in star-forming galaxies is driven by recent star formation, not a secondary source of ionisation. It is thought that the diffuse ionised gas (DIG) is ionised …
[2404.19003] Implications on star-formation-rate indicators from HII ...
2024年4月29日 · Abstract: We examine the connection between diffuse ionised gas (DIG), HII regions, and field O and B stars in the nearby spiral M101 and its dwarf companion NGC 5474 …
The Impact of HII Regions on the Interstellar Medium of our Galaxy
Using Green Bank Telescope (GBT) pointed radio recombination line (RRL) data of a subset of Galactic HII regions and fully-sampled RRL maps from the GBT Diffuse Ionized Gas Survey …
spectral properties of HII regions and DIG in M31, we chose several targets for spectroscopic observation. This paper presents the optical spectrophotometric results of a sample of 44 …
