Are High-redshift Galaxies Hot? Temperature of z > 5 Galaxies and Implications for Their Dust Properties [PDF]
, 2017 Recent studies have found a significant evolution and scatter in the relationship between the UV spectral slope (βUV) and the infrared excess (IRX; LIR/LUV) at z > 4, suggesting different dust properties of these galaxies.

Self-consistent proto-globular cluster formation in cosmological simulations of high-redshift galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We report the formation of bound star clusters in a sample of high-resolution cosmological zoom-in simulations of z ≥ 5 galaxies from the Feedback In Realistic Environments project.

The [CII] 158 micron line emission in high-redshift galaxies [PDF]
, 2017 The [CII] fine structure transition at 158 microns is the dominant cooling line of cool interstellar gas, and is the brightest of emission lines from star forming galaxies from FIR through meter wavelengths.

Measuring dynamical masses from gas kinematics in simulated high-redshift galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Advances in instrumentation have recently extended detailed measurements of gas kinematics to large samples of high-redshift galaxies. Relative to most nearby, thin disc galaxies, in which gas rotation accurately traces the gravitational potential, the

On the Number of Galaxies at High Redshift [PDF]
Galaxies, 2015 The number of galaxies at a given flux as a function of the redshift, z, is derived when the z-distance relation is non-standard. In order to compare different models, the same formalism is also applied to the standard cosmology. The observed luminosity function for galaxies of the zCOSMOS catalog at different redshifts is modeled by a new luminosity ...

Structural and Morphological Properties of Ultraluminous Infrared Galaxies at 1 < z < 3
Open Astronomy, 2015 Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR > 1012L⊙) at 1 < z < 3. Their rest-
