Chasing Lyman alpha-emitting galaxies at z = 8.8
Peter Laursen, Jesper Sommer-Larsen, Bo Milvang-Jensen +2
With a total integration time of 168 hours and a narrowband (NB) filter tuned to Lyman alpha at z = 8.8, the UltraVISTA survey has set out to find some of the most distant galaxies…
Intergalactic Transmission and its Impact on the Lyα Line
Peter Laursen, Jesper Sommer-Larsen, Alexei O. Razoumov
We study the intergalactic transmission of radiation in the vicinity of the Lyα wavelength. Simulating sightlines through the intergalactic medium (IGM) in detailed cosmological hy…
Ionizing radiation from z=4-10 galaxies
Alexei O. Razoumov, Jesper Sommer-Larsen
We compute the escape of ionizing radiation from galaxies in the redshift interval z=4-10, i.e., during and after the epoch of reionization, using a high-resolution set of galaxies…
DLA kinematics and outflows from starburst galaxies
Alexei O. Razoumov
We present results from a numerical study of the multiphase interstellar medium in sub-Lyman-break galaxy protogalactic clumps. Such clumps are abundant at z=3 and are thought to b…
Can gravitational infall energy lead to the observed velocity dispersion in DLAs?
Alexei O. Razoumov, Michael L. Norman, Jason X. Prochaska +3
The median observed velocity width v_90 of low-ionization species in damped Ly-alpha systems is close to 90 km/s, with approximately 10% of all systems showing v_90 > 210 km/s at z…
Modeling Lyman continuum emission from young galaxies
Alexei O. Razoumov, Jesper Sommer-Larsen
Based on cosmological simulations, we model Lyman continuum emission from a sample of 11 high-redshift star forming galaxies spanning a mass range of a factor 20. Each of the 11 ga…
