Can the intergalactic medium cause a rapid drop in Lyman alpha emission at z>6?
Andrei Mesinger, Aycin Aykutalp, Eros Vanzella +3
The large cross-section of the Lyman alpha (Lya) line makes it a sensitive probe of the ionization state of the intergalactic medium (IGM). Here we present the most complete study…
The Response of Metal Rich Gas to X-Ray Irradiation from a Massive Black Hole at High Redshift: Proof of Concept
A. Aykutalp, J. H. Wise, R. Meijerink +1
Observational studies show that there is a strong link between the formation and evolution of galaxies and the growth of supermassive black holes (SMBH) at their centers. However,…
Testing the Proposed Connection between Dark Energy and Black Holes
A. Aykutalp, M. Spaans
In 1997, an extension of general relativity was proposed that predicts the dark energy density Λ to vary linearly with the total number of macroscopic black holes in the universe.…
The complexity that the first stars brought to the Universe: Fragility of metal enriched gas in a radiation field
Aycin Aykutalp, Marco Spaans
The initial mass function (IMF) of the first (Population III) stars and Population II (Pop II) stars is poorly known due to a lack of observations of the period between recombinati…
The impact of metallicity and X-rays on star formation
Marco Spaans, Aycin Aykutalp, Seyit Hocuk
Star formation is regulated through a variety of feedback processes. In this study, we treat feedback by metal injection and a UV background as well as by X-ray irradiation. Our ai…
