Type Ic Supernovae are a type of supernova that exhibit strong Si II absorption lines in their optical spectra, similar to Type Ia supernovae. They are characterized by the absence of hydrogen and helium lines, and are known for their high luminosities and uniform temporal evolution. ...
We calculate the Type Ia supernova rates through an analytical formulation which rests upon the definition of the SN Ia rate following an instantaneous burst of star formation as a function of the time elapsed from the birth of the progenitor system to its explosion as a Type Ia supernova (...
Describe the different fates of the different types of stars. Also, explain the differences between Type I and Type II supernovae. Explain the difference between a phyllosilicate sheet and a layer. What are the differences between diamond and graphite?
where m is the apparent magnitude and M is the absolute magnitude of the measured supernova, while per definition we have the Hubble uncertainty parameter as h¯=H(z)100kms.Mpc with H(z) is the Hubble parameter. Now that we have a model, we will use 359 low- and intermediate redshi...
Recently there have been suggestions that the Type Ia supernova data can beexplained using only general relativity and cold dark matter with no darkenergy... RA Vanderveld,ÉÉ Flanagan,I Wasserman - 《Physical Review D》 被引量: 100发表: 2008年 Quasispherical gravitational collapse A previou...
Constraints on the model parameters were imposed from the updated 57 points of Hubble data sets, and 580 points of union 2.1 compilation supernovae data sets. The performed analysis did show that f(Q, T) gravity represents a promising approach for explaining the current cosmic acceleration, and...
