The HDUV Survey: A Revised Assessment of the Relationship between UV Slope and Dust Attenuation for High-redshift Galaxies [PDF]

, 2017
We use a newly assembled sample of 3545 star-forming galaxies with secure spectroscopic, grism, and photometric redshifts at z = 1.5–2.5 to constrain the relationship between UV slope (β) and dust attenuation (LIR/LUV ≡ IRX).

The erratic dynamical life of black hole seeds in high-redshift galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2019
The dynamics of black hole seeds in high redshift galaxies is key to understand their ability to grow via accretion and to pair in close binaries during galactic mergers.

The physics of Lyman α escape from high-redshift galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Lyman-alpha (Ly{\alpha}) photons from ionizing sources and cooling radiation undergo a complex resonant scattering process that generates unique spectral signatures in high-redshift galaxies. We present a detailed Ly{\alpha} radiative transfer study of a

RECONCILING THE STELLAR AND NEBULAR SPECTRA OF HIGH-REDSHIFT GALAXIES [PDF]

, 2016
We present a combined analysis of rest-frame far-UV (FUV; 1000–2000 Å) and rest-frame optical (3600–7000 Å) composite spectra formed from very deep Keck/LRIS and Keck/MOSFIRE observations of a sample of 30 star-forming galaxies with , selected to be ...

Searching for high-z DSFGs with NIKA2 and NOEMA [PDF]

EPJ Web of Conferences, 2022
As the possible progenitors of passive galaxies at z=2-3, dusty starforming galaxies (DSFGs) at z>4 provide a unique perspective to study the formation, assembly, and early quenching of massive galaxies in the early Universe.

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.

Nearly all the sky is covered by Lyman-α emission around high-redshift galaxies [PDF]

Nature, 2018
Galaxies are surrounded by large reservoirs of gas, mostly hydrogen, that are fed by inflows from the intergalactic medium and by outflows from galactic winds.

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-

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.

Relativistic jet feedback in high-redshift galaxies – I. Dynamics [PDF]

, 2016
We present the results of three dimensional relativistic hydrodynamic simulations of interaction of AGN jets with a dense turbulent two-phase interstellar medium, which would be typical of high redshift galaxies.
