Extensible/rule based query rewrite optimization in Starburst

Hamid Pirahesh, Joseph M. Hellerstein, Waqar Hasan
1992 Proceedings of the 1992 ACM SIGMOD international conference on Management of data - SIGMOD '92  
We present a suite of rewrite rules used in Starburst to transform queries into equivalent queries for faster execution, and also describe the production rule engine which is used by Starburst to choose  ...  and execute these rules.  ...  Many extensions have been added to Starburst [LLPS91], including XNF, a system supporting complex object queries which often generates extremely complicated SQL queries.  ...

Starbursts in isolated galaxies

Ch. Theis, J. Köppen
2009 Astronomy and Astrophysics  
The impact of the stellar birth function, the initial mass function (IMF), the stellar feedback and the interstellar medium (ISM) model are investigated.  ...  Starbursts and substantial variations in the star formation histories are a common phenomenon in galaxies.  ...  We thank Jay Gallagher, Simone Recchi, and Shu-ichiro Inutsuka for stimulating discussions on starbursts and induced star formation.  ...

Starbursts in Isolated Galaxies?

AChandraX-ray survey of nearby dwarf starburst galaxies - II. Starburst properties and outflows

Jürgen Ott, Fabian Walter, Elias Brinks
2005 Monthly notices of the Royal Astronomical Society  
The number of X-ray point sources appears to be a function of the current star formation rate and the blue luminosity of the hosts.  ...  The power law index of the combined cumulative X-ray point source luminosity function is alpha=0.24+/-0.06, shallower than that of more massive starburst galaxies (alpha=0.4-0.8) and of non-starburst galaxies  ...  ACKNOWLEDGEMENTS We would like to thank Dominik Bomans, John Cannon, Deidre Hunter, Chip Kobulnicky, Vince McIntyre, and Stefanie Mühle for providing optical, Hα and H i images of the galaxies.  ...

THE ENVIRONMENTS OF STARBURST AND POST-STARBURST GALAXIES ATz= 0.4-0.8

Bianca M. Poggianti, Alfonso Aragón-Salamanca, Dennis Zaritsky, Gabriella De Lucia, Bo Milvang-Jensen, Vandana Desai, Pascale Jablonka, Claire Halliday, Gregory Rudnick, Jesus Varela, Steven Bamford, Philip Best (+7 others)
2009 Astrophysical Journal  
Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star formation activity ended  ...  Our observations are consistent with previous suggestions that cluster k+a galaxies are observed in a transition phase as massive S0 and Sa galaxies, evolving from star-forming later types to passively  ...  Even more significant is to look at the incidence of poststarbursts and dusty starburst candidates among the active population as a function of local density (Figure 13 ).  ...

The starbursts in the Milky Way [article]

The Fossil Starburst in M82

Richard de Grijs, Robert W. O'Connell, John S. Gallagher III
2001 Astronomical Journal  
This region, M82 "B," has been suspected to be a fossil starburst site in which an intense episode of star formation occurred over 100 Myr ago, and our new observations confirm this intepretation.  ...  After correcting the cluster luminosity function to a fiducial age of 50 Myr, we find that the bright end is characterized by a power-law slope with alpha = -1.2 +/- 0.3.  ...  The di †erence between F555W m ST (F814W) [ 23.5 and Johnson V is F555W[V^0.02 to 0.05 for A0V to O5V spectral types, and between F814W and Cousins I is F814W[I D [1.1 to [1.2 for similar spectral-type  ...

Multi-phase outflows in post starburst E+A galaxies – I. General sample properties and the prevalence of obscured starbursts [article]

Dalya Baron, Hagai Netzer, Dieter Lutz, J. Xavier Prochaska, Ric I. Davies
2021 arXiv   pre-print
Using IRAS-FIR observations, we study the star formation in these systems and find that many systems selected to have post starburst signatures in their optical spectrum are in fact obscured starbursts  ...  E+A galaxies are believed to be a short phase connecting major merger ULIRGs with red and dead elliptical galaxies.  ...  While there are no O or B-type stars in post starburst galaxies, there may be enough A-type stars to heat the dust and produce a significant FIR emission.  ...
