The Horizon-AGN simulation: evolution of galaxy properties over cosmic time [PDF]
, 2016 We compare the predictions of Horizon-AGN, a hydro-dynamical cosmological simulation that uses an adaptive mesh refinement code, to observational data in the redshift range 0 6.

CONSTRAINTS ON BLACK HOLE/HOST GALAXY CO-EVOLUTION AND BINARY STALLING USING PULSAR TIMING ARRAYS [PDF]
, 2016 Pulsar timing arrays are now setting increasingly tight limits on the gravitational wave background from binary supermassive black holes (SMBHs). But as upper limits grow more constraining, what can be implied about galaxy evolution? We investigate which

It is not easy being green: the evolution of galaxy colour in the EAGLE simulation [PDF]
, 2016 We examine the evolution of intrinsic u-r colours of galaxies in the EAGLE cosmological hydrodynamical simulations, which has been shown to reproduce the observed redshift z=0.1 colour-magnitude distribution well.

3D-HST+CANDELS: THE EVOLUTION OF THE GALAXY SIZE–MASS DISTRIBUTION SINCE z = 3 [PDF]
, 2014 Spectroscopic+photometric redshifts, stellar mass estimates, and rest-frame colors from the 3D-HST survey are combined with structural parameter measurements from CANDELS imaging to determine the galaxy size–mass distribution over the redshift range 0 ...

Introducing the Illustris Project: the evolution of galaxy populations across cosmic time [PDF]
, 2014 We present an overview of galaxy evolution across cosmic time in the Illustris Simulation. Illustris is an N-body/hydrodynamical simulation that evolves 2*1820^3 resolution elements in a (106.5Mpc)^3 box from cosmological initial conditions down to z=0 ...

Strong Progenitor Age Bias in Supernova Cosmology and Alignment with DESI BAO
UniverseSupernova (SN) cosmology is based on the assumption that the luminosity of type Ia SNe, after the luminosity standardization process, remains invariant with progenitor age.

The origin and evolution of the galaxy mass–metallicity relation [PDF]
, 2015 We use high-resolution cosmological zoom-in simulations from the Feedback in Realistic Environment (FIRE) project to study the galaxy mass–metallicity relations (MZR) from z=0–6.

New Insight on Galaxy Formation and Evolution from Keck Spectroscopy of the Hawaii Deep Fields [PDF]
, 1996 We present the results of spectroscopic studies with the LRIS spectrograph on Keck of two of the Hawaii deep survey fields. The 393 objects observed cover an area of 26.2 square arcmin and constitute a nearly complete sample down to K = 20, I = 23, and B

Dust-regulated galaxy formation and evolution: a new chemodynamical model with live dust particles [PDF]
, 2015 Interstellar dust plays decisive roles in the conversion of neutral to molecular hydrogen (H_2), the thermodynamical evolution of interstellar medium (ISM), and the modification of spectral energy distributions (SEDs) of galaxies.

CIGALE: a python Code Investigating GALaxy Emission [PDF]
Astronomy & Astrophysics, 2018 Context. Measuring how the physical properties of galaxies change across cosmic times is essential to understand galaxy formation and evolution. With the advent of numerous ground-based and space-borne instruments launched over the past few decades we ...
