Massive black holes or stars first: the key is the residual cosmic electron fraction
Muhammad A. Latif, Sadegh Khochfar
Recent James Webb Space Telescope observations have unveiled that the first supermassive black holes (SMBHs) were in place at z 10, a few hundred Myrs after the Big Bang. Th…
Black hole formation in the context of dissipative dark matter
M. A. Latif, A. Lupi, D. R. G. Schleicher +3
Black holes with masses of dwell in the centers of most galaxies, but their formation mechanisms are not well known. A subdominant dissipative component o…
Assessing inflow rates in atomic cooling halos: implications for direct collapse black holes
M. A. Latif, M. Volonteri
Supermassive black holes are not only common in the present-day galaxies, but billion solar masses black holes also powered quasars. One efficient way to form such black…
Impact of baryonic streaming velocities on the formation of supermassive black holes via direct collapse
M. A. Latif, J. C. Niemeyer, D. R. G. Schleicher
Baryonic streaming motions produced prior to the epoch of recombination became supersonic during the cosmic dark ages. Various studies suggest that such streaming velocities change…
Magnetic fields during the formation of supermassive black holes
M. A. Latif, D. R. G. Schleicher, W. Schmidt
Observations of quasars at report the existence of a billion solar mass black holes. Comprehending their formation in such a short time scale is a matter of ongoing rese…
The characteristic black hole mass resulting from direct collapse in the early universe
M. A. Latif, D. R. G. Schleicher, W. Schmidt +1
Black holes of a billion solar masses are observed in the infant universe a few hundred million years after the Big Bang. The direct collapse of protogalactic gas clouds in primord…
The formation of massive Pop III stars in the presence of turbulence
M. A. Latif, D. R. G. Schleicher, W. Schmidt +1
Population III stars forming in the infant universe at z=30 heralded the end of the cosmic dark ages. They are presumed to be assembled in so-called minihaloes with virial temperat…
Massive black hole factories: Supermassive and quasi-star formation in primordial halos
Dominik R. G. Schleicher, Francesco Palla, Andrea Ferrara +2
Supermassive stars and quasi-stars (massive stars with a central black hole) are both considered as potential progenitors for the formation of supermassive black holes. They are ex…
Impact of an accurate modeling of primordial chemistry in high resolution studies
S. Bovino, T. Grassi, M. A. Latif +1
The formation of the first stars in the Universe is regulated by a sensitive interplay of chemistry and cooling with the dynamics of a self-gravitating system. As the outcome of th…
Black hole formation in the early universe
M. A. Latif, D. R. G. Schleicher, W. Schmidt +1
Supermassive black holes with up to a dwell in the centers of present-day galaxies, and their presence has been confirmed at z 6. Their formation at s…
The small scale dynamo and the amplification of magnetic fields in massive primordial haloes
M. A. Latif, D. R. G. Schleicher, W. Schmidt +1
While present standard model of cosmology yields no clear prediction for the initial magnetic field strength, efficient dynamo action may compensate for initially weak seed fields…
Magnetic fields during high redshift structure formation
Dominik R. G. Schleicher, Muhammad Latif, Jennifer Schober +6
We explore the amplification of magnetic fields in the high-redshift Universe. For this purpose, we perform high-resolution cosmological simulations following the formation of prim…
High resolution studies of massive primordial haloes
M. A. Latif, D. R. G. Schleicher, W. Schmidt +1
Atomic cooling haloes with virial temperatures K are the most plausible sites for the formation of the first galaxies and the first intermediate mass blac…
The implications of dust for high-redshift protogalaxies and the formation of binary disks
M. A. Latif, D. R. G. Schleicher, M. Spaans
Numerical simulations suggest that the first galaxies are formed in protogalactic halos with virial temperatures >= 10^4 K. It is likely that such halos are polluted with trace amo…
Lyman alpha emission from the first galaxies: Implications of UV backgrounds and the formation of molecules
M. A. Latif, Dominik R. G. Schleicher, M. Spaans +1
The Lyman alpha line is a robust tracer of high redshift galaxies. We present estimates of Lyman alpha emission from a protogalactic halo illuminated by UV background radiation fie…
Lyman alpha emission from the first galaxies: Signatures of accretion and infall in the presence of line trapping
M. A. Latif, Dominik. R. G. Schleicher, M. Spaans +1
The formation of the first galaxies is accompanied by large accretion flows and virialization shocks, during which the gas is shock-heated to temperatures of K, leading…
The Impact of Lyman alpha Trapping on the Formation of Primordial Objects
M. A. Latif, S. Zaroubi, M. Spaans
Numerous cosmological simulations have been performed to study the formation of the first objects. We present the results of high resolution 3-D cosmological simulations of primord…
