Galaxy Manifold: Characterizing and understanding galaxies with two parameters
Suchetha Cooray, Tsutomu T. Takeuchi, Daichi Kashino +3
We report the discovery of a two-dimensional Galaxy Manifold within the multi-dimensional luminosity space of local galaxies. The multi-dimensional luminosity space is constructed…
An Empirical Estimation of the Galaxy Radio Number Counts model at 3~GHz and the Effect of Gravitational Lensing
K. T. Kono, T. T. Takeuchi
We analyzed the evolution of 3GHz luminosity function of radio selected galaxies through cosmic time, up to about 1 Gyr after Big Bang, with making use of the VLA-COSMOS3GHz large…
Constraining the luminosity function of active galactic nuclei through the reionization observations in the SKA era
Kai T. Kono, Taichi Takeuchi, Hiroyuki Tashiro +2
Ultraviolet (UV) and X-ray photons from active galactic nuclei (AGNs) can ionize hydrogen in the intergalactic medium (IGM). We solve radiative transfer around AGNs in high redshif…
Constructing a multivariate distribution function with a vine copula: toward multivariate luminosity and mass functions
Tsutomu T. Takeuchi, Kai T. Kono
The need for a method to construct multidimensional distribution function is increasing recently, in the era of huge multiwavelength surveys. We have proposed a systematic method t…
