Anomalous Microwave Emission from Star Forming Regions
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation. These detections, in combination with statistical constraints on its presence on large angular scales in the diffuse ISM, have provided strong observational ...

Spectral Properties of Some IRAS Starburst Galaxies at HI 21-cm statistic study [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 Many research deal with physical properties of HI gas in all types of galaxies.The 21cm data analysis allows to measure spectral and radio properties for galaxies, so it allows to study physical operation that assistant in starformation. We interest here

SYNCHRONIZED FORMATION OF STARBURST AND POST-STARBURST GALAXIES IN MERGING CLUSTERS OF GALAXIES [PDF]
The Astrophysical Journal, 2010 We propose that synchronized triggering of star formation in gas-rich galaxies is possible during major mergers of cluster of galaxies, based on new numerical simulations of the time evolution of the physical properties of the intracluster medium (ICM) during such a merger event.

RELATIONSHIP BETWEEN STAR FORMATION RATE AND BLACK HOLE ACCRETION AT z = 2: THE DIFFERENT CONTRIBUTIONS IN QUIESCENT, NORMAL, AND STARBURST GALAXIES [PDF]
, 2015 We investigate the co-evolution of the black hole accretion rate (BHAR) and the star formation rate (SFR) in 1.5 < z < 2.5 ?> galaxies displaying a greater diversity of star-forming properties compared to previous studies.

Overtone Transition 2ν1 of HCO+ and HOC+: Origin, Radiative Lifetime, Collisional Quenching
ChemPhysChem, Volume 25, Issue 21, November 4, 2024.The C−H/O−H stretch vibration overtone of one of the simplest molecular ion isomeric systems HCO+/HOC+ is studied in a cryogenic ion trap experiment. Moreover, our comprehensive “zero background” method enables the determination of radiative lifetimes and select quenching reaction rates at the same time.

Properties of the Hii Regions Derived Using Integral Field Spectroscopy
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 Here we review some of our more recent results on the observed properties of Hii regions using Integral Field Spectroscopy. In particular, we illustrate the use of this technique to study in detail the ionization conditions across the nebulae for galactic Hii regions (focused on the Orion Nebula) and the statistical study of large samples of ...

Cosmic axion background propagation in galaxies
Physics Letters B, 2016 Many extensions of the Standard Model include axions or axion-like particles (ALPs). Here we study ALP to photon conversion in the magnetic field of the Milky Way and starburst galaxies. By modelling the effects of the coherent and random magnetic fields,

Starbursts in barred spiral galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 1998 This paper presents optical long-slit spectroscopic observations of 105 barred Markarian IRAS galaxies. These observations are used to determine the spectral type of emission-line regions in the nucleus and along the bar of the galaxies, in order to define a homogeneous sample of Starburst Nucleus Galaxies (SBNGs). Our selection criteria have been very

Local starburst galaxies and their descendants. Statistics from the Sloan Digital Sky Survey [PDF]
, 2015 Despite strong interest in the starburst phenomenon in extragalactic astronomy, the concept remains ill-defined. Here we use a strict definition of starburst to examine the statistical properties of starburst galaxies in the local universe.
