Galaxy merger statistics and inferred bulge-to-disk ratios in cosmological SPH simulations
formation spiral elliptical
2014/12/24
We construct merger trees for galaxies identified in a cosmological hydrodynamic simulation and use them to characterize predicted merger rates as a function of redshift, galaxy mass, and merger mass ...
An AzTEC 1.1 mm survey of the GOODS-N field - I. Maps, catalogue and source statistics
detectors sub-millimetre
2014/12/23
We have conducted a deep and uniform 1.1 mm survey of the Great Observatories Origins Deep Survey-North (GOODS-N) field with AzTEC on the James Clerk Maxwell Telescope. Here, we present the first resu...
Primordial Non-Gaussianity and Extreme-Value Statistics of Galaxy Clusters
Primordial Non-Gaussianity Extreme-Value Statistics Galaxy Clusters
2011/10/20
What is the size of the most massive object one expects to find in a survey of a given volume? In this paper, we present a solution to this problem using Extreme-Value Statistics. We calculate the pro...
Chi-square versus median statistics in SNIa data analysis
Chi-square versus median statistics SNI data analysis
2011/10/12
In this paper we compare the performances of the chi-square and median likelihood analysis in the determination of cosmological constraints using type Ia supernovae data. We perform a statistical anal...
On the pulse-width statistics in radio pulsars. II. Importance of the core profile components
stars:pulsars:general – stars:neutron – stars:rotation
2011/9/27
We performed a statistical analysis of half-power pulse-widths of the core components in average pulsar profiles. We confirmed an existence of the lower bound of the distribution of half-power pulse-w...
