From dark matter halos to pre-stellar cores: High resolution follow-up of cosmological Lyman-Werner simulations
Lewis R. Prole, Anna T. P. Schauer, Paul C. Clark +3
Molecular hydrogen allows cooling in primordial gas, facilitating its collapse into Population III stars within primordial halos. Lyman-Werner (LW) radiation from these stars can e…
Dwarf galaxy formation with and without dark matter-baryon streaming velocities
Anna T. P. Schauer, Michael Boylan-Kolchin, Katelyn Colston +4
We study how supersonic streaming velocities of baryons relative to dark matter -- a large-scale effect imprinted at recombination and coherent over Mpc scales -- affects…
On the probability of the extremely lensed =6.2 Earendel source being a Population~III star
Anna T. P. Schauer, Volker Bromm, Niv Drory +1
The recent discovery of the extremely lensed Earendel object at is remarkable in that it is likely a single star or stellar multiple, observed within the first billion year…
Formation of proto-globular cluster candidates in cosmological simulations of dwarf galaxies at
Omid Sameie, Michael Boylan-Kolchin, Philip F. Hopkins +8
We perform cosmological hydrodynamical simulations to study the formation of proto-globular cluster candidates in progenitors of present-day dwarf galaxies $(M_{\rm vir} \approx 10…
Metal Mixing in Minihalos: The Descendants of Pair-Instability Supernovae
Mattis Magg, Anna T. P. Schauer, Ralf S. Klessen +3
The lack of observations of abundance patterns originating in pair-instability supernovae has been a long-standing problem in relation to the first stars. This class of supernovae…
Globular Clusters and Streaming Velocities: Testing the new formation channel in high-resolution cosmological simulations
Anna T. P. Schauer, Volker Bromm, Michael Boylan-Kolchin +2
The formation of globular clusters and their relation to the distribution of dark matter have long puzzled astronomers. One of the most recently-proposed globular cluster formation…
The influence of streaming velocities and Lyman-Werner radiation on the formation of the first stars
Anna T. P. Schauer, Simon C. O. Glover, Ralf S. Klessen +1
The first stars in the Universe, the so-called Population III stars, form in small dark matter minihaloes with virial temperatures ~K. Cooling in these miniha…
The Ultimately Large Telescope -- what kind of facility do we need to detect Population III stars?
Anna T. P. Schauer, Niv Drory, Volker Bromm
The launch of the James Webb Space Telescope will open up a new window for observations at the highest redshifts, reaching out to z~15. However, even with this new facility, the fi…
Shape and Spin of Minihaloes. II: The Effect of Streaming Velocities
Maik Druschke, Anna T. P. Schauer, Simon C. O. Glover +1
Models of the decoupling of baryons and photons during the recombination epoch predict the existence of a large-scale velocity offset between baryons and dark matter at later times…
Constraining the non-gravitational scattering of baryons and dark matter with early cosmic structure formation
Boyuan Liu, Anna T. P. Schauer, Volker Bromm
We derive new constraints on the non-gravitational baryon-dark-matter scattering (BDMS) by evaluating the mass thresholds of dark matter (DM) haloes in which primordial gas can coo…
Constraining First Star Formation with 21cm-Cosmology
Anna T. P. Schauer, Boyuan Liu, Volker Bromm
Within standard CDM cosmology, Population III (Pop III) star formation in minihalos of mass M provides the first stellar sources of…
The Influence of Streaming Velocities on the Formation of the First Stars
Anna T. P. Schauer, Simon C. O. Glover, Ralf S. Klessen +1
How, when and where the first stars formed are fundamental questions regarding the epoch of Cosmic Dawn. A second order effect in the fluid equations was recently found to make a s…
Shape and Spin of Minihaloes: From Large Scales to the Centres
Maik Druschke, Anna T. P. Schauer, Simon C. O. Glover +1
The spin and shape of galaxies at the present day have been well-studied both observationally and theoretically. At high redshifts, however, we have to rely on numerical simulation…
The formation of direct collapse black holes under the influence of streaming velocities
Anna T. P. Schauer, John Regan, Simon C. O. Glover +1
We study the influence of a high baryonic streaming velocity on the formation of direct collapse black holes (DCBHs) with the help of cosmological simulations carried out using the…
Lyman-Werner Escape Fractions from the First Galaxies
Anna T. P. Schauer, Bhaskar Agarwal, Simon C. O. Glover +6
Direct collapse black holes forming in pristine, atomically-cooling haloes at may act as the seeds of supermassive black holes (BH) at high redshifts. In order to…
Lyman-Werner UV Escape Fractions from Primordial Halos
Anna T. P. Schauer, Daniel J. Whalen, Simon C. O. Glover +1
Population III stars can regulate star formation in the primordial Universe in several ways. They can ionize nearby halos, and even if their ionizing photons are trapped by their o…
The Mystery of the -Bump -- A new Signature for Major Mergers in Early-type Galaxies?
Anna T. P. Schauer, Rhea-Silvia Remus, Andreas Burkert +1
The stellar velocity dispersion as a function of the galactocentric radius of an early-type galaxy can generally be well approximated by a power law . However, some o…
