The evolution of the number density of galaxies in the universe, and thus also the total number of galaxies, is a fundamental question with implications for a host of astrophysical problems including galaxy evolution and cosmology. However there has never been a detailed study of this important measurement, nor a clear path to answer it. To address this we use observed galaxy stellar mass functions up to z _ 8 to determine how the number densities of galaxies changes as a function of time and… Expand

Metallicity of stars formed throughout the cosmic history based on the observational properties of star forming galaxies
Metallicity is one of the crucial factors that determine stellar evolution. To characterize the properties of stellar populations one needs to know the fraction of stars forming at different… Expand
Evolution of the galaxy stellar mass functions and UV luminosity functions at z = 6−9 in the Hubble Frontier Fields
We present new measurements of the evolution of the galaxy stellar mass functions (GSMF) and UV luminosity functions (UV LF) for galaxies from $z=6-9$ within the Frontier Field cluster… Expand
The Universal Rotation Curve of Dwarf Disc Galaxies Created by the Most Massive Disc Galaxies
According to the Scale-Symmetric Theory (SST), visible mass (or baryonic mass) of most massive disc galaxies is about 0.85 multiplied by both 12 powers of ten and the solar mass. Calculated within… Expand
The COSMOS2015 galaxy stellar mass function . Thirteen billion years of stellar mass assembly in ten snapshots
We measure the stellar mass function (SMF) and stellar mass density of galaxies in the COSMOS field up to z ~ 6. We select them in the near-IR bands of the COSMOS2015 catalogue, which includes… Expand
Major mergers are not the dominant trigger for high-accretion AGNs at z = 2
Research over the past decade has shown diminishing empirical evidence for major galaxy mergers being a dominating or even important mechanism for the growth of supermassive black holes in galaxies… Expand
Terrestrial planets across space and time
The study of cosmology, galaxy formation and exoplanets has now advanced to a stage where a cosmic inventory of terrestrial planets may be attempted. By coupling semi-analytic models of galaxy… Expand
The Multi-Bang Universe: The Never-Ending Realm of Galaxies
A new cosmological model is proposed for the dynamics of the Universe and the formation and evolution of galaxies. It is shown that the matter of the Universe contracts and expands in cycles, and… Expand
What can we learn from pulsar timing arrays (or not) : constraining astrophysical parametric models with gravitational waves
Super massive black holes have been found in the centre of massive galaxies, which have also been observed to merge. Consequently, the central black holes should also form a binary and merge when… Expand
Constraining the era of helium reionization using fast radio bursts
The discovery of fast radio bursts (FRBs) about a decade ago opened up new possibilities for probing the ionization history of the Intergalactic Medium (IGM). In this paper we study the use of FRBs… Expand
The effect of the environment-dependent IMF on the formation and metallicities of stars over the cosmic history
Recent observational and theoretical studies indicate that the stellar initial mass function (IMF) varies systematically with the environment (star formation rate - SFR, metallicity). Although the… Expand
