Radio-to-Far-Infrared Spectral Energy Distribution and Photometric Redshifts for Dusty Starburst Galaxies
galaxies photometric
2014/12/26
As a logical next step in improving the radio-to-submillimeter spectral index as a redshift indicator, we have investigated a technique of using the entire radio-to-far-infrared spectral energy distri...
We present an X-ray study of our nearest starburst galaxy IC 10, based on XMM–Newton and Chandra observations. A list of 73 XMM–Newton and 28 Chandra detections of point-like X-ray sources in the fiel...
We report the spectroscopic confirmation of a submillimeter galaxy (SMG) at z = 4.547 with an estimated LIR = (0.5-2.0) × 1013 L. The spectra, mid-IR, and X-ray properties indicate the bolometric lumi...
OBSERVATIONS OF STARBURST GALAXIES WITH FAR-ULTRAVIOLET SPECTROGRAPHIC EXPLORER: GALACTIC FEEDBACK IN THE LOCAL UNIVERSE
starburst halos
2014/12/22
We have analyzed FUSE (905-1187 ? spectra of a sample of 16 local starburst galaxies. These galaxies cover almost three orders of magnitude in star-formation rates and over two orders of magnitude in ...
Far-infrared line imaging of the starburst ring in NGC 1097 with the Herschel/PACS spectrometer
Seyfert nucleus interstellar medium
2014/12/20
NGC 1097 is a nearby SBb galaxy with a Seyfert nucleus and a bright starburst ring. We study the physical properties of the interstellar medium (ISM) in the ring using spatially resolved far-infrared ...
THE REDSHIFT AND NATURE OF AzTEC/COSMOS 1: A STARBURST GALAXY AT z = 4.6*
broadband narrowband photometry
2014/12/20
Based on broadband/narrowband photometry and Keck DEIMOS spectroscopy, we report a redshift of z = 4.64+0.06 –0.08 for AzTEC/COSMOS 1, the brightest submillimeter galaxy (SMG) in the AzTEC/COSMOS fiel...
Constraining Stellar Feedback: Ionized Gas Structures In Local Starburst Galaxies
Pure sciences Ionized gas structures Interstellar medium Starburst galaxies Stellar feedback
2014/12/9
Stellar feedback, i.e., the return of mechanical energy from supernova explosions, and massive star and AGN winds to the interstellar medium, is one of the fundamental processes that shape galaxy evol...
A multifrequency view of starburst galaxies
starburst galaxies – high-energy photons –cosmic rays – molecular ions
2011/10/12
During the past few years, first observations of starburst galaxies at >GeV energies could be made with the Fermi Gamma-ray Space Telescope (GeV range) and Imaging Air Cherenkov Telescopes (TeV range)...

The massive binary population the starburst cluster Westerlund 1
2011/1/13
We present initial results from a long-baseline radial velocity survey for massive binaries in the cluster Westerlund 1. Four systems are examined: the dust-producing WC binary W239, the double-lined...
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.
Shaken, Not Stirred: The Disrupted Disk of the Starburst Galaxy NGC 253
galaxies individual (NGC 253) – galaxies evolution – galaxies
2010/11/15
Near-infrared images obtained with WIRCam on the Canada-France-Hawaii Telescope are used to investigate the recent history of the nearby Sculptor Group spiral NGC 253, which is one of the nearest star...
Starburst radio galaxies: general properties, evolutionary histories and triggering
galaxies active – galaxies jets – galaxies starburst – galaxies:interactions
2010/11/12
In this paper we discuss the results of a programme of spectral synthesis modelling of
a sample of starburst radio galaxies in the context of scenarios for the triggering of the
activity and the evo...
W49A: A starburst triggered by expanding shells
massive star formation starburst giant molecular cloud UC Hii region molecular bubble
2010/11/11
Aims. W49A is a giant molecular cloud which harbors some of the most luminous embedded clusters in the Galaxy. However, the explanation for this starburst-like phenomenon is still under debate.
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...
Comparison of AGN and Nuclear Starburst Activity in Seyfert 1 and 2 Galaxies over a Wide Luminosity Range Based on Near-infrared 2-4 micrometer Spectroscopy
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present near-infrared K- (1.9-2.5 micrometer) and L- (2.8-4.2 micrometer) band spectroscopy of 22 Seyfert nuclei. We use two methods to investigate the presence of nuclear starbursts.
