The first power spectrum limit on the 21-cm signal of neutral hydrogen during the Cosmic Dawn at z=20-25 from LOFAR
B. K. Gehlot, F. G. Mertens, L. V. E. Koopmans +19
Observations of the redshifted 21-cm hyperfine line of neutral hydrogen from early phases of the Universe such as Cosmic Dawn and the Epoch of Reionization promise to open a new wi…
The neutral gas extent of galaxies as derived from weak intervening CaII absorbers
P. Richter, F. Krause, C. Fechner +2
(Abridged) We present a systematic study of weak intervening CaII absorbers at low redshift (z<0.5), based on the analysis of archival high resolution (R>45,000) optical spectra of…
On the starting redshift for cosmological simulations: Focusing on halo properties
Alexander Knebe, Christian Wagner, Steffen Knollmann +2
We systematically study the effects of varying the starting redshift z_i for cosmological simulations in the highly non-linear regime. Our primary focus lies with the (individual)…
