Probing the initial mass function of the first stars with transients
Alexanders Lazar, Volker Bromm
The emergence of the first, so-called Population III (Pop III), stars shaped early cosmic history in ways that crucially depends on their initial mass function (IMF). However, beca…
Detectability of Population III stellar remnants as X-ray binaries from tidal captures in the local Universe
Rabia Husain, Boyuan Liu, Volker Bromm
We assess the feasibility of detecting the compact object remnants from Population III (Pop III) stars in nearby dense star clusters, where they become luminous again as X-ray bina…
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…
Gravitational waves from the remnants of the first stars in nuclear star clusters
Boyuan Liu, Volker Bromm
We study Population III (Pop III) binary remnant mergers in nuclear star clusters (NSCs) with a semi-analytical approach for early structure formation. Within this framework, we ke…
Highly r-process enhanced stars in ultra-faint dwarf galaxies
Myoungwon Jeon, Gurtina Besla, Volker Bromm
Highly r-process enhanced metal-poor stars (MP r-II, and ) have been observed in ultra-faint dwarf (UFD) galaxy, specifically in Reticulum~I…
Stellar winds and metal enrichment from fast-rotating Population III stars
Boyuan Liu, Yves Sibony, Georges Meynet +1
Stellar winds from fast-rotating Population III (Pop III) stars have long been suspected to make important contributions to early metal enrichment, as features in the nucleosynthes…
