When summed up, all of the dusty, star-forming galaxies in the Universe produce an infrared radiation field that has an equal energy density as the direct starlight emission from all galaxies visible at ultraviolet and optical wavelengths. The bulk of this infrared extragalactic background light ...
1) star-forming galaxies 恒星形成星系1. Our aims are to study the oxygen abundance of the star-forming galaxies , to study the estimating methods and the calibration relations. 本论文主要研究了恒星形成星系的氧丰度,测量方法以及定标关系。
We determine the intrinsic, 3-dimensional shape distribution of star-forming galaxies at 0 1e10 Msol) disks are the most common geometric shape at all z < 2. Lower-mass galaxies at z>1 possess a broad range of geometric shapes: the fraction of elongated (prolate) galaxies increases toward...
<italic>Context.</italic> The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy surveys allow now to study these processes in great detail at intermediate redshif
Star-forming galaxies rule gamma-ray sky4 November 2021 Diffuse sky Fermi–LAT’s five-year sky map, indicating the various diffuse components that make up 80% of all photons detected. Credit: NASA The diffuse photon background that fills the universe does not limit itself to the attention-...
Dwarf galaxies are the least massive, most abundant and most widely distributed type of galaxy. Hence, they are key to testing theories of galaxy and Universe evolution. Dwarf galaxies sufficiently close to have their gas and stellar components studied i
"In most distant starburst galaxies, stars are actively formed in the center. So it is surprising to find off-center clouds," said Tadaki. With the new observations, the researchers found that the monster galaxy was powered by "an extremely gas-heavy disk that is somehow kept stable until ...
Lyman-alpha (Lya) photons that escape the interstellar medium of star-forming galaxies may be resonantly scattered by neutral hydrogen atoms in the circumgalactic and intergalactic media, thereby increasing the angular extent of the galaxy's Lya emission. We present predictions of this extended, low...
Results show that while most SED parameters decrease with radius, the emissivity index beta also decreases with radius in some galaxies, but in others is increasing, or rising in the inner regions and falling in the outer ones. Despite the fixed grain emissivity (average beta~ 2.1) of the ...
