Why Do Starburst Galaxies 'Burst'? ALMA Sees Super Stellar Nurseries at Heart of Sculptor Galaxy
Starburst Galaxies Burst Super Stellar Nurseries Heart of Sculptor Galaxy
2015/3/4
Starburst galaxies transmute gas into new stars at a dizzying pace – up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while others...
Genesis and evolution of dust in galaxies in the early Universe I. Modeling dust evolution in starburst galaxies
galaxies high-redshift – galaxies starburst – galaxies evolution – ISM evolution – quasars general – stars massive
2010/11/16
Aims. The aim is to elucidate the astrophysical conditions required for generating large amounts of dust in massive starburst galaxies at high redshift.
Diffuse Hard X-ray Emission in Starburst Galaxies as Synchrotron from Very High Energy Electrons
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The origin of the diffuse hard X-ray emission of starburst galaxies is a long-standing problem. We suggest that synchrotron emission of 10 - 100 TeV electrons and positrons can contribute significantl...
Gamma-rays from Pulsar Wind Nebulae in Starburst galaxies (HEAD 2010)
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/29
Recently, two nearby prominent starburst galaxies, M82 and NGC253, have been detected as point-like sources with gamma-ray telescopes at TeV energies [1] [2]. It has been claimed that these detections...
Gamma-rays from pulsar wind nebulae in starburst galaxies
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
Recently, gamma ray emission at TeV energies has been detected from the starburst galaxies NGC253 [1] and M82 [2].
PAH and Emission Line Ratios in AGN and Starburst Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We study the Polycyclic Aromatic Hydrocarbons (PAH) bands, ionic emission lines, and Mid-infrared continuum properties, in a sample of 171 emission line galaxies taken from literature plus 15 new acti...
