Formation of SMBH seeds in Pop III star clusters through collisions : the importance of mass loss
P. J. Alister Seguel, D. R. G. Schleicher, T. C. N. Boekholt +2
Runaway collisions in dense clusters may lead to the formation of supermassive black hole (SMBH) seeds, and this process can be further enhanced by accretion, as recent models of S…
The 3D structure of CO depletion in high-mass prestellar regions
S. Bovino, S. Ferrada-Chamorro, A. Lupi +3
Disentangling the different stages of the star-formation process, in particular in the high-mass regime, is a challenge in astrophysics. Chemical clocks could help alleviating this…
The role of gas fragmentation during the formation of supermassive black holes
Matías Suazo, Joaquín Prieto, Andrés Escala +1
We have performed cosmological hydrodynamic simulations to study the effect of fragmentation on the SMBH seed mass in the direct collapse formation scenario. We considered differen…
Intermittent fragmentation and statistical variations during gas collapse in magnetised atomic cooling haloes
Philipp Grete, Muhammad A. Latif, Dominik R. G. Schleicher +1
Observations reveal the presence of supermassive black holes (SMBH) as early as ~700 million years after the Big Bang. Their formation path is still subject to current debate. We e…
Discovery of a nitrogen-enhanced mildly metal-poor binary system: Possible evidence for pollution from an extinct AGB Star
José G. Fernández-Trincado, Ronald Mennickent, Mauricio Cabezas +13
We report the serendipitous discovery of a nitrogen-rich, mildly metal-poor ([Fe/H]=-1.08) giant star in a single-lined spectroscopic binary system found in the SDSS-IV Apache Poin…
A timeline for massive star-forming regions via combined observation of o-HD and ND
A. Giannetti, S. Bovino, P. Caselli +6
Context: In cold and dense gas prior to the formation of young stellar objects, heavy molecular species (including CO) are accreted onto dust grains. Under these conditions H…
