Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
Impact of radiation backgrounds on the formation of massive black holes
V. B. Díaz, D. R. G. Schleicher, S. Bovino +4
The presence of supermassive black holes (SMBHs) of a few billion solar masses at very high redshift has motivated us to study how these massive objects formed during the first bil…
Synthetic observations of HD towards high-mass starless cores
Joaquin. Zamponi F., Dominik R. G. Schleicher, Stefano Bovino +3
Young massive stars are usually found embedded in dense and massive molecular clumps and are known for being highly obscured and distant. During their formation process, deuteratio…
Star formation at high redshift
P. Fibla, S. Bovino, R. Riaz +4
We present here a three-dimesional hydrodynamical simulation for star formation. Our aim is to explore the effect of the metal-line cooling on the thermodynamics of the star-format…
Formation of the First Black Holes: Current observational status
Dominik R. G. Schleicher
In this chapter, we review the current observational status of the first supermassive black holes. It is clear that such a review can hardly be complete, due to the wealth of surve…
The formation of protostellar binaries in primordial minihalos
Rafeel Riaz, Stefano Bovino, Siegfried Vanaverbeke +1
The first stars are known to form in primordial gas, either in minihalos with about ~M or so-called atomic cooling halos of about ~M. Simulations have s…
Magnetic fields in star forming systems (I): Idealized synthetic signatures of dust polarization and Zeeman splitting in filaments
Stefan Reissl, Amelia M. Stutz, Robert Brauer +3
We use the POLARIS radiative transport code to generate predictions of the two main observables directly sensitive to the magnetic field morphology and strength in filaments: dust…
Collisions in Primordial Star Clusters: Formation Pathway for intermediate mass black holes
B. Reinoso, D. R. G. Schleicher, M. Fellhauer +2
Collisions were suggested to potentially play a role in the formation of massive stars in present day clusters, and have likely been relevant during the formation of massive stars…
H-band discovery of additional Second-Generation stars in the Galactic Bulge Globular Cluster NGC 6522 as observed by APOGEE and Gaia
José G. Fernández-Trincado, O. Zamora, Diogo Souto +34
We present elemental abundance analysis of high-resolution spectra for five giant stars, deriving Fe, Mg, Al, C, N, O, Si and Ce abundances, and spatially located within the innerm…
