THE PROGENITORS OF THE COMPACT EARLY-TYPE GALAXIES AT HIGH REDSHIFT [PDF]
, 2013 We use GOODS and CANDELS images to identify progenitors of massive (M > 1010 M☉) compact early-type galaxies (ETGs) at z ∼ 1.6. Because merging and accretion increase the size of the stellar component of galaxies, if the progenitors are among known star ...

Creation Field Cosmological Model with Variable Cosmological Term (Λ) in Bianchi Type III Space‐Time
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The paper is devoted to the study of cosmological models with time‐varying cosmological term (Λ) in the presence of creation field in the framework of Bianchi type III space‐time. To obtain deterministic model of the universe, we have assumed Λ ∝ 1/R3, where R is the scale factor, for steady state cosmology and creation field, and shear (σ) is ...

THE COEVOLUTION OF SUPERMASSIVE BLACK HOLES AND MASSIVE GALAXIES AT HIGH REDSHIFT [PDF]
, 2013 We exploit the recent, wide samples of far-infrared (FIR) selected galaxies followed up in X-rays and of X-ray/optically selected active galactic nuclei (AGNs) followed up in the FIR band, along with the classic data on AGNs and stellar luminosity ...

The MaGICC volume: reproducing statistical properties of high-redshift galaxies [PDF]
, 2013 We present a cosmological hydrodynamical simulation of a representative volume of the Universe, as part of the Making Galaxies in a Cosmological Context (MaGICC) project. MaGICC uses a thermal implementation for supernova and early stellar feedback. This

CONTAMINATION OF BROADBAND PHOTOMETRY BY NEBULAR EMISSION IN HIGH-REDSHIFT GALAXIES: INVESTIGATIONS WITH KECK'S MOSFIRE NEAR-INFRARED SPECTROGRAPH [PDF]
, 2013 Earlier work has raised the potential importance of nebular emission in the derivation of the physical characteristics of high-redshift Lyman break galaxies.

Galaxy bulges at mid- and high-redshift [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractBulges are a major galaxy component in the nearby universe, and are one of the primary features that differentiates and defines galaxies. The origin of bulges can be directly probed in part by examining distant galaxies to search for high redshift bulges, and to study the properties of bulges in formation.

Interpreting the observed UV continuum slopes of high-redshift galaxies [PDF]
, 2013 The observed UV continuum slope of star-forming galaxies is strongly affected by the presence of dust. Its observation is then a potentially valuable diagnostic of dust attenuation, particularly at high redshift where other diagnostics are currently ...

Radiative transfer in a clumpy universe: The colors of high-redshift galaxies
, 1995 We assess the effects of the stochastic attenuation produced by intervening QSO absorption systems on the broadband colors of galaxies at cosmological distances.
