Stars were born in significantly denser regions in the early Universe [PDF]
, 2014 The density of the warm ionized gas in high-redshift galaxies is known to be higher than what is typical in local galaxies on similar scales. At the same time, the mean global properties of the high- and low-redshift galaxies are quite different.

Constraining Cosmic Evolution of Type Ia Supernovae [PDF]
, 2007 We present the first large-scale effort of creating composite spectra of high-redshift type Ia supernovae (SNe Ia) and comparing them to low-redshift counterparts.

Variable G versus the Accelerated Expansion of the Universe
Open Astronomy, 2017 It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the ...

Measurement of redshift dependent cross correlation of HSC clusters and Fermi $\gamma$ rays [PDF]
, 2019 The cross-correlation study of the unresolved $\gamma$-ray background (UGRB) with galaxy clusters has a potential to reveal the nature of the UGRB. In this paper, we perform a cross-correlation analysis between $\gamma$-ray data by the Fermi Large Area ...
